7 Characteristics Associated with Long Life (and How to Cultivate Them)

Be Happy!As much as we focus on food and fitness as the “physical” arbiters of health and longevity, there appears to be much more to it. In fact, most research fails to find any grand commonalities in the diet and fitness patterns of the longest lived. From Okinawans with their sweet potatoes to Japanese centenarians with their dairy to the Ashkenazi with their higher rates of smoking, drinking, and lower rates of formal exercise to the 107 year old with her butter, no exercise, and mistrust of medicine to the supercentenarians with their liver, bacon, wine, chocolate, and eggs to the other supercentenarians with their caloric restriction. Sure, they’re generally not eating Twinkies and Panda Express, but the secret to longevity – at least as it’s practiced by living centenarians – does not lie in one specific diet.

So what is it? One main determinant appears to be whether you have certain alleles. You can’t change that (not yet anyway), but there are some things you can control. What you can affect – and what appears to have a big effect on, or at least a strong association with longevity – are personality traits and characteristics. How you see the world. How you engage life. How you interact with others. Now, to be sure, many personality traits are somewhat out of your conscious control, whether genetically determined or set in motion by events long-past, but that doesn’t mean you can’t try to cultivate or emulate them.

What are some of these characteristics?

Socially Connected

Perhaps one of the prime directives of the human is to be social. To have friends and loved ones upon whom you can lean when required or desired. I’m not necessarily talking about being the guy with a thousand Facebook friends who’s out every night living it up, or even the lady who always runs into someone she knows when out and about. Socially connected simply means having meaningful relationships with other people. It could be ten, twenty, or five. The point is that it helps to have actual, real friends and loved ones, and we’re probably evolutionarily driven to want and make them because they provide a benefit to survival.

Why might social connections support longevity? The research is ongoing, but I can think of a few reasons. First, people with meaningful relationships can call on them for help in times of need and hardship. Need some rent money or to pay for an important surgical procedure? You can probably count on friends and family to help. Recovering from said surgical procedure and need someone to help you get groceries and cook? Call a friend or family member. Need a ride? Call someone you know. If you don’t know anyone you can count on, your options will be limited.

Second, social isolation and loneliness are often associated with negative health patterns, like obesity, inactivity, and smoking. Plus, the socially isolated and lonely are more likely to have hypertension, elevated inflammatory markers, and increased blood clotting. In one study, people who had close friends in the same room with them had less of a blood pressure and heart rate increase in response to stress. Another study found that in people exposed to a cold virus, those with more social connections were less likely to actually get sick than those with fewer social connections.

It’s good to have friends. All else being equal, the person who’s happy with their relationships is probably going to live longer than the person who’s unhappy with or bereft of social connections.


  • Use social networks like Facebook and Meetup to arrange real life activities and augment your social lives. Make plans with friends and follow up on them. Join a Meetup group that sounds interesting and attend the events. It’s easy to let social media replace our social interactions, but it’s not a preordained inevitability.
  • Don’t be that person who regrets not calling/contacting their friends more. Some people truly have no friends or family, but that’s rare. More often than not, people just aren’t willing to make the effort, maybe because they don’t see the need, maybe because they’re lazy, maybe because they’re anxious, or maybe because they’re waiting for the other person to contact them. Be proactive in fostering and maintaining the relationships you already have.


According to health researchers Howard Friedman and Leslie Martin, conscientiousness is a big (perhaps the biggest) influence on longevity. Using data from a study that began in 1921 and followed a group of 1500 boys and girls into old age and beyond, the two found that the kids who were “prudent, persistent, planful” went on to live the longest lives, while the “cheerful and optimistic” children lived shorter lives. The former group tended to take fewer risks, be more responsible about their health, and cultivate a better social network. They also had more satisfying and successful professional lives. Overall, the persistent, industrious, organized, and disciplined “facets of conscientiousness” were most strongly associated with longevity.

This connection is well-researched. Conscientious people tend to be healthier and take better care of themselves. Childhood conscientiousness is linked to better health later on in life. Most of the connection between conscientiousness and longevity can be explained by obvious factors, like the fact that thoughtful people are more likely to care about their diet and other health-related behaviors and therefore make better health-related decisions, but not all of it. Conscientiousness, for example, also seems to go hand-in-hand with cognitive function and it may even be protective against Alzheimer’s and other diseases of cognitive degeneration. Those who are conscientious may also deal with stress better than those who are not, probably by virtue of being better prepared for it.

There’s got to be a balance, though, I’d imagine. What if conscientiousness veers into obsession? What if dedication to self-discipline devolves into self-flagellation? What if hard work becomes workaholicism and breaks up your marriage?


  • Practice, practice, practice. Make schedules and budgets. Plan out your day, and hew to the plan. If you aren’t naturally disciplined and organized, you can still become conscientious – it’s just gonna be a bit harder. 
  • Don’t just self-analyze. Ask others close to you about their perception of your conscientiousness, and adjust accordingly. After all, the original 1921 study analyzed the kids’ personalities by asking their parents, not the kids themselves.

Don’t Worry Too Much

Longer lived people (and waterfowl) are able to let things slide off their backs. They tend to be easy going and don’t get hung up on silly stuff as much. Consider the interplay with conscientiousness, however. Just as too much conscientiousness might manifest as obsessiveness and lead to poorer health and longevity, being too carefree might lead to poor decision-making and flagrant abuse of one’s health. A balance is likely best, where you don’t sweat the small stuff enough to heap unnecessary stress upon your back but take the important aspects of life seriously.


  • Don’t cry over spilled milk (unless it’s raw and comes from grass-fed Jersey cows, of course). Better yet, get down on the floor and lap it all up. 
  • Forgive people. If there’s something you’ve been mulling over, some perceived slight, some past transgression, consider forgiving that person and moving on. 
  • When you’re worked up about something, stop and ask yourself what exactly is bothering you so much. Get specific when you answer. You might just find there’s nothing there. 
  • Make a list of all the things you tend to worry about. Then, objectively analyze the relative “seriousness” of each item. Discard the items that aren’t very serious. Make specific plans to take care of the serious items that merit your attention. Once this is completed, you’ll have discarded the frivolous stressors and made plans to tackle the serious ones. The point is you’ll have less to worry about now.
  • Look into Stoicism. Here’s a decent representation of what it’s all about. You can’t control everything, and you have to be okay with that.
  • Explore stress-reducing herbs and teas.
  • Meditate.


Seemingly contrary to the other findings about optimistic kids dying earlier, some research suggests that optimism is a good predictor of longevity. Optimists are more resistant to stress, generally lead longer and healthier lives than pessimists, and, well, optimism seems to be encoded into our genome. According to neuroscientist Tali Sharot, “optimism was selected by evolution precisely because, on balance, positive expectations enhance the odds of survival.”

I wrote about this last year. Optimists, quite simply, are fighters. They’re fighters because they can see a point to it all, a light glimmering at the end of the tunnel, and so they continue on. They don’t give up, because why would you if things are going to work out? To an optimist, things only fail because you gave up on them. If you’re faced with a cancer diagnosis – say, lung cancer – and you’re an optimist, you’re more likely to survive longer.


  • Look at the bright side of a “bad” situation. That’s it. Just look at it. Perceive it. Observe it. Acknowledge it. When you do that in an objective way, you can’t help but feel a little better about the situation.
  • Throw yourself out there anyway. Things aren’t that bad. Trust me. When you actually go out and face it and it goes okay, you’ve just learned that things aren’t always as bad as you assume.
  • Get those small wins that lead to big success (and optimism).

Easy to Laugh

There’s considerable research that ease of laughter is a strong predictor of longevity. He who laughs most, laughs last, in other words. Laughter isn’t just enjoyable. It’s also really good for you. It reduces stress and improves natural killer cell (a part of your immune system responsible for fighting cancer and other diseases) activity. It lowers cortisol. While growth hormone is best known for its fat-burning effects, it can also have a negative impact in rheumatoid arthritis; laughter reduces the RA-associated growth hormone increase. Overall, laughter simply has “positive, quantifiable effects on certain aspects of health.”


  • Watch funny media. Whether you like Laurel and Hardy or Tim and Eric, find something that you determine generates a high level of mirthful activity in your brain and expose yourself to it, repeatedly. 
  • Watch standup. I recommend Louis CK.
  • Just laugh. This sounds obvious, but you don’t even have to find something funny in order to laugh. In the immortal words of George Costanza, “What is the point of opening your mouth and going ‘Ha-ha!’?” It’s that easy. Force yourself to laugh and the real feelings will likely follow. Do this once a day, minimum.
  • Try laughter yoga. It’s exactly what it sounds like.


In 2011, a study of older men and women found that those who were happiest throughout the day lived the longest. Interestingly, this association was independent of baseline health status or other variables, suggesting that momentary happiness “may be causally related to survival, or may be a marker of underlying biological, behavioral, or temperamental factors.” Even those with chronic diseases saw longevity benefits from being happy.

I think this comes down to something very simple: happy people have “something to live for.” They have a reason to get out of bed in the morning. Yeah, yeah, a meaningful career, grandkids, a loving spouse, a faithful dog – these are all good reasons to keep living. But when it comes down to it, if you can wake up confident in the fact that your day is going to be an enjoyable, happy one, you will live better and live longer.


  • Live life. Unless we’re talking chemically-induced happiness, happiness doesn’t just spring up out of nothing. You are happy because good things are happening in real, actual life. Maybe you just got a puppy or a girlfriend. Maybe you got a great new job. Maybe you’re reading a good book. Maybe you went on a hike and the flowers were blooming. The point is happiness is a reaction to happy events. You’re not really going to be able to “think yourself” happy. 
  • Do things that you know you’re going to enjoy and appreciate even if they require momentary unhappiness. You know how you’re always happy when you get up early enough to do some gardening (or hike, or work out, or clean the kitchen, or make a good breakfast) before it gets too hot (or late), but getting out of bed to actually do it is a short struggle that you usually lose? Just do it anyway. It’s not that bad. Play the long game.


Extraversion is a significant predictor of longevity, happiness, resistance to stress, and even mood regulation in the face of unpleasant situations. I tend to suspect that introverts might not live as long not because of something inherent to introverts, but because modern society is geared toward and favors extraversion. An introvert probably experiences more stress in response to social fundamentals, like job interviews, small talk, presentations, and anything else where extraversion helps. You can be introverted and completely comfortable with that fact and be totally fine, or at least minimize the downsides. But if you’re an introvert who’s unhappy, who’s envious of extroverts, you may suffer.

Also, extraversion is more “costly.” A study of older adults found that in order to maintain their psychological well-being, extraverts needed large social networks.


  • Act the part. Even though social interaction may be more difficult for introverts, “acting like” an extrovert can increase well-being just the same, even in introverts
  • Start a conversation at least once a day. Go up and talk to people.
  • Introversion does not imply social isolation. You may not be the life of the party, but you can still have quality relationships – perhaps just with fewer people.

That’s about it for today, folks. I hope this was a helpful post and that you can begin cultivating some of these traits in your own lives. Be sure to let me know what you think – any good anecdotes about the personalities of long-lived people you’ve known?

You want comments? We got comments:

Imagine you’re George Clooney. Take a moment to admire your grooming and wit. Okay, now imagine someone walks up to you and asks, “What’s your name?” You say, “I’m George Clooney.” Or maybe you say, “I’m the Clooninator!” You don’t say “I’m George of George Clooney Sells Movies Blog” and you certainly don’t say, “I’m Clooney Weight Loss Plan”. So while spam is technically meat, it ain’t anywhere near Primal. Please nickname yourself something your friends would call you.

      Bryan wrote on May 15th, 2013
      • That’s only the immediate effect of sugar. The long term effects of sugar consumption are an increase in stress and destabilization of mood-related neurotransmitters. It is also highly addictive which increases its tendency to induce stress long term.

        • This just happened to me. (Primal – 2 years with some major battles). Thanks to a sugar addiction that reared its ugly head I fell off the wagon HARD. My stress level and anxiety increased, my emotional stability went off kilter and I destabilized my mood-related neurotransmitters (I have GABA, DPLA, and 5-HTP with me right now and am doing a bit more research on a decent regimen until I’m fully repleted). YOU HIT THE NAIL ON THE HEAD. (I’m HIGHLY SENSITIVE to sugar). I triggered my Fibromyalgia AND Reactive Hypoglycemia. Could they be connected? My N=1 tells me yes since they always seem to show up around the same time. AND – thanks to 5-HTP I now have full neck movement for the first time in 2 months. And I know it was the 5-HTP because about 2 hours after my second pill on the second day my neck/shoulder pain and stiffness dissipated in a matter of minutes. My neck has been a pleasant warm. Body ache is pretty much gone. All this took 3 days of supplements. I didn’t eat a lot – no appetite – during this time but made a point to get some good protein when I did. And NO SUGAR!

    • They may be funny, but I’m not sure that type of humor is the life-extending one. I think you’ll get a lot farther with humor that makes you laugh off yourself rather than laughing off other people. Thoughts that promote understanding of yourself or others would be more beneficial than thoughts that promote the demeaning of other people.

        If you don’t mostly agree with their political point of view, much of the humor element is gone from the get go. I used to love Jon Stewart but then I changed my mind on several issues over the course of a decade. He is still funny to a certain extent, but I’ve become much more aware of how much the humor rests on mocking people he doesn’t agree with. When I watch a clip or two now I find myself in a half cringe/half laugh state.

        I tend to gravitate now more towards more universal/personal humor – laughing at the craziness that connects all of us. And of course, the best stuff is the crazy situations I get myself into. :)

  5. Being happy seems like the obvious one to me. If you manage that you’re likely taking care of many others. You’re probably avoiding stress, likely are optimistic and have meaningul relationships.

    Ohhhh and at all cost avoid the life suckers and life haters. The people who are just miserable, unhappy, and unwillinging to challenge or help their situation. No time for that!

    Luke wrote on May 15th, 2013
    • I believe “happiness” is just another emotion that we experience as human beings like joy, anger, sadness, fear, peace, contentment. It’s not possible to be happy all of the time therefore I strive to experience all of the positive emotions most of the time knowing that the negative ones will creep in from time to time and that’s OK. That’s life after all…

      Ara wrote on May 16th, 2013
  6. “You are happy because good things are happening in real, actual life.”

    What I’ve heard is that most (depressed) people think that once they have different feelings they’ll be able to do different things. But the opposite is true: You do different things, this causes you to have different thoughts which causes you to have different feelings. So do happy things, you’ll have happy thoughts and this will lead to happy feelings.

  8. These are all incredibly interesting to me. I’ve observed the same characteristics to be true – after profiling 23+ people that lived to 100, they almost always mentioned the same things:

    -Have fun, don’t stress
    -Be happy, do work you enjoy
    -Stay connected and be social
    – Never stop working

    … And just this overall relaxed feeling about life, a very Taoist kinda “Eh, what will happen will happen.”

    No doubt that many of us in the 21st century are killing ourselves by rushing and not taking time to smell the roses.

  9. “…the kids who were “prudent, persistent, planful” went on to live the longest lives, while the “cheerful and optimistic” children lived shorter lives

    Is it true that the former lived longer than the latter, or did it just seem that way? I prefer a shorter, cheerful and optimistic life.

    Jim wrote on May 15th, 2013
    • I think that was worded poorly, since being cheerful and optimistic are characteristics listed as being correlated with longevity. The way I interpreted it was that the “cheerful and optimistic” ones were those that didn’t think too much about what they were doing (e.g. Just eat as much sugar as you want? Sure, it’ll be fine.), while the “prudent, persistent, planful” people were the ones that tried to figure out the best way to live, set goals, and worked towards them. That doesn’t preclude them being cheerful and optomistic about it.

    • Harry, you and I seem to think a lot alike. I also see all the bad things in the world and used to despair of humanity. But then I spent some time cultivating a long-term view of life that didn’t just look at humanity, but rather life as a whole. We may have messed up our current incarnation of “civilisation”, but if you look at history, this has happened many many times before and humanity just carried on with something new. Even if we manage to wipe ourselves out and kill off most life on the planet, not to despair, even when 95% of life was wiped out, the creatures that evolved to take their place were better. Life is bigger than just us, just this planet, just humanity or the life on this planet. Spend some time watching documentaries on the universe and the natural history of the planet and start to see things in millions and billions of years, instead of human life times. It worked for me – I’m prudent (I’ve planned for what I will do if things go wrong) and I’m optimistic because I know that life continues, no matter what. And evolution always means something better is out there. Maybe not humans, maybe something much better than us.

The kids had school to attend, husband had a job to go to, but I had to make my own way or stay at home lonely and bored. I hated it at first, but now I’m quite grateful. I always say hello to strangers I pass while I’m out hiking or walking, even in a foreign country. They look at me a little strange, but usually greet me back – it’s wonderful!

      • Its not easy for introverts to feel confident among strangers, but it is possible. Having a job which forced me to interact on the phone with lots of manufacturers and then face clients that I have never met before really gave me confidence. Nobody cares about how you sound, or a mistake you might make. It really doesn’t matter in the long run. People will remember you and be happier if you reach out to them. It may feel really uncomfortable at first, but it does get easier, have faith.
        Maybe there is a club or organization that focuses on something you love in your community, find it and get involved. Each interaction will get easier and easier!

    • You’re not nessesarily an extrovert just because you walk into a room and say hello. I’m a very private person myself and I’m definitely not an extrovert however I think it’s nice manors to say hello when you come to work in the morning and smile to your colleagues. I generally go by the philosophy: leave your shit at home don’t bring it to work and bother your colleagues – and if it’s just bad that day- TELL THEM! That way they know you’re not dragging negatitivity around towards them and that you’re just having a bad day (everyone does at some point) I have no problem small talking either etc but I generally don’t like being forced into social gatherings or making presentations etc. where I feel exposed or can’t get my privacy. Theres studies that show introverts and extroverts recharge their energy differently – extroverts gain energy from being around people (the more the better) whereas introverts gain energy by being alone with their thoughts. Since society as the article states favors extroverts, introverts are under pressure to get enough alone space which generally means its easier to be extroverted. It would be cool if society actually appreciated both types. I’d like to link to this YouTube video of TED talks about how introverts actually benefits society – so maybe introverts should stop worrying and actually feel better about being what they are.

      There’s nothing wrong with being an introvert and we aren’t negative depressed people running around its just a different way of charging your energy and being more comfortable alone it doesn’t mean you aren’t social or don’t have friends.

      • Thank you! Being an INFJ and reading that last part was infuriating (ok, maybe annoying at best). Introverts trying to meet extrovert mold is likely the causative agent for why they don’t live as long. Since I’ve accepted my introvert side and actually “recharge”, I love and appreciate my friends and family so much more. Plus I don’t feel lonely because I’m “supposed” to be around people all the time.

    • Always annoying when people associate extraversion with happiness/health… as far as I know the only studies done on this basically equated the number of people’s contact info you have with the number of friends, which translated into more happiness.

      I wouldn’t be surprised if this whole longevity/extroversion thing is bullshit. Even Carl Jung back in his day noticed that society is very pro-extro & anti-introversion. Not much has changed since then, except asians seem to be more pro-introversion. This is sad; it means extroverts will never learn of their own weaknesses & forced to change like introverts do, while introverts will always be undervalued.

  13. I highly disagree with the assertion that you have to have happy “events” in your life to be happy. Happiness is a state of mind, and where does it come from if not from your mind? You can ONLY think yourself into happiness. Well, you could think yourself into happiness, or you can think yourself into sadness. The amount of work is the same, and the choice is up to you.

But perspective is key. I was a pessimist for most of my childhood and teenage years, even though I had a pretty good life. This attitude led to a lot of problems, until I learned that my circumstances did not have to determine whether I was happy or not. I have gradually taught my self to have an optimistic view of life, but it wasn’t easy.

  17. What are your thoughts on research by Dan Buettner and others into the commonalities among long-lived people in the so-called “Blue Zones” (including Okinawa)?

    He identified 9 common traits in these “longevity zones” – 1) move naturally, 2) have a purpose, 3) slow down/reduce stress, 4) don’t eat too much (until 80% full), 5) eat a largely plant based diet, 6) consume moderate amounts (1-2 glasses) of wine each day, 7) find belonging through faith/community, 8) put loved ones first, 9) surround yourself with people who support healthy behaviors.

    There is some overlap with your list, but it also goes a little further to adress other aspects of diet and lifestyle.

    Brian wrote on May 15th, 2013

          My great-grandfather was the longest lived of any of my relatives. Died in his 90’s. Ate pancakes, eggs, bacon, and smoked. Never saw a hospital until the last 2 months of his life. I’m sure he would have gotten a big chuckle out of being told to not eat meat because it was bad for him.

    • I hit the “Blue Zone” website and took a looked at the five they have there. The initial issue that stands out for me is community size. Most of the Blue Zones are tiny communities and that’s critical, to me anyway. It wouldn’t take much net immigration or out to skew their age numbers.

      For instance, I know that most Italian hill towns are on the verge of dying off. The young people are leaving for better prospects in urban Italy. Here’s a quote from the site “In a cluster of 17 white washed villages in island’s highland Nuoro, Province [Italy], you find nearly 10 times the number of centenarians per 1000 people than you do in America.”

      If these small villages are mostly only older people, then I would expect a much higher percentage of centenarians people even if they smoke, drink, and routinely throw themselves at rabid dogs. 😉 There’s no young people left to “dilute” percentage, because they’ve all left for other parts of the world. It’s a bit like visiting a nursing home and marveling at the extremely high percentage of people who made it past 65.

      I’m inclined to think that the whole “Blue Zone” is mostly just wishful thinking. It’s easy to find a tiny group that supports your nutritional/lifestyle thesis. I’ve seen it countless times on my Net travels. I’m more interested in what connects long lived healthy people across many cultures, rather than older communities.

      Amy wrote on May 15th, 2013
      • I read the book and some of the related research and felt that the issue of community size is well considered, though there are definitely a LOT of challenges to studying longevity. Some of the communities, like the 7th Day Adventists in Loma Linda, CA are actually rather large. This study, which is heavily referenced in the book, had 96,000 subjects:

        Like Mark’s article, the Blue Zones work is about trying to understanding the commonalities among communities with exceptional longevity. They started by identifying those places, the “blue zones” and then visiting them, conducting interviews, looking at diet, etc. Personally I think some of the conclusions are a little too qualitative, but some do have a quantitative research behind them.

  18. This really resonated with me. Growing up, I was actually the opposite of most of the things in the list. It wasn’t until I started taking steps to become more healthy that I noticed a change in how I feel. Never underestimate the power of a healthy diet on how the brain (and mind) functions. I truly believe what you eat can eventually affect how you feel and perceive yourself.

    Before I was eating healthy, I would try my hardest to feel normal–to be okay in social situations, to not feel anxious or irritable, etc. Willpower is not enough, in my opinion. Once I went primal, the first difference I noticed was in my mental health, and it’s only gotten better. I feel so much more balanced than I used to. Granted, I’m still somewhat introverted, but I feel much less anxious around people.

    But, if I go off the diet for a few days or I’m around chemicals (like paint), I will start to notice some of those unhealthy thought patterns creep back in. Since I know what is causing it, I can accept what I am feeling instead of blaming myself or feeling guilty about my feelings.

    However, I can only speak for my experiences; others may find it to be different for them.

    • I find this to be exactly true for myself as well, and I’m so glad that the PB has taken away my guilt from those bad decision moments because now I understand why I feel the way I do, which allows me to get back on track since I know I will feel better. I know Mark has explored this before, but the mind/body connection is so important to me; when I feed my body what it needs, my mind directly benefits, and makes me want to continue to do so. I cannot simply will myself to feel better when consuming SAD foods because their effects on my mind and body are just too much.

      I’m confident that currently being primal at least 70% of the time and constantly working to up that percentage, will have a huge effect on not only the longevity of my life but the quality as well. Grok on!

      • Anna,

        Thanks so much! I think other people don’t understand until they’ve lived through it. I used to get upset at people who were depressed because I didn’t understand how they were feeling. I thought they could just “go for a walk” or “think happy thoughts,” and they would feel better. Now, I know it really doesn’t have to do with your mind; it’s more of a brain thing. If your body is unhealthy, your brain will be, too.

        It’s refreshing to hear from other people with this viewpoint. Even in this community (where we don’t blame people for being “fat and lazy”), people still tend to blame people for their feelings.

        I find that since I have adopted my beliefs about the body/mind connection, I have a lot more compassion for people. I understand more of what they are going through and why they feel the way they do. I think that could be another word Mark could add to that list: compassionate. The more compassion and empathy we have for people, the less stressed and more content we will feel.

        • “I thought they could just “go for a walk” or “think happy thoughts,” and they would feel better…I find that since I have adopted my beliefs about the body/mind connection, I have a lot more compassion for people.”

          I must admit that I need to work on the compassion part. It’s hard though. The problem is that I grew up a Mother who spent most of her adult life “severely depressed”, even when she wasn’t.

          For the record, she is very much prone to depression. I’m very much convinced diet is on of the core issues. However, she early in her adult life she discovered that having mental health issues were a sort of “get out of jail free” card for her problems. The people she encountered were so compassionate (including my father) that they became enablers of some very negative habits.

          She never took even the most basic advise to improve her mood. (Like regular walks, etc) I can’t blame her for the low-fat craze, but even then, she knew sugar was problematic and still had a fair amount around the house when we were growing up.

          Apparently, no one on the “outside”, ie, everyone else knew anything about how hard her life was, or how it might be improved, etc. She is/was a true purple snowflake I guess.

          When she did finally get sick of feeling bad (or sick of taking meds), she would take the absolute worst advice because usually she took none at all. That led to some interesting adventures, including her initiating a divorce she came to regret 12 years later. But we all had to understand and accept her mostly selfish behavior because she was “severely depressed”.

          I absolutely believe her depressive fits are real and that they are rooted in her physical issues. Unfortunately, she is/was ironically content to be miserable and rely on the kindness of strangers. My own compassion towards her died away long ago.

          It is important that people take responsibility for their actions and emotions, if they feel crummy or even clinically depressed. Depression explains some sort term issues and people will forgive you if you consistently try to take action. Once it becomes a label and a lifestyle,though, it stinks.

I can’t help but feel that focusing on centenarians for clues to long life is like looking at A students for clues to the best teaching methods: A students get A’s regardless of how good (or bad) the learning environment.

  20. Actually there are others things that centenarians have in common.
    For one thing they all eat REAL food, regardless of the precise ratio of macro-nutrients. They tend to cook their own food, which of course means eating less processed and fast foods.
    Also, most super centenarians have a high fat diet.
    They also tend to be more active then most people, even if they don’t do intensive exercise, they spend less time sitting.
    Centenarians also have relatively low insulin, blood sugar and triglycerides for their age. While this can be largely explained by genetic factors, we are still able to achieve the same bio-markers regardless of our genetics by adhering to an appropriate paleo diet.

  21. I hate the advice to “try to act like an extrovert” for introverts. Like most introverts I was pushed all through my childhood, teens and 20s to be more social, but that’s just not me.

    Higher energy people and groups of people just suck the life out of me, mentally and physically. Imagine every day of your life being the stress equivalent of the mall at Christmas or Walmart on Black Friday, and that’s what a “normal” life feels like to an introvert.

    Instead I would say cultivate the relationships and activities that give you joy. I used to come home from work exhausted and depressed, often too tired to eat before falling into bed. My weight skyrocketed and I was very unhealthy. Now I am perfectly happy working from home, puttering in the yard/garden, watching the dogs bicker and play, and taking a walk when my brain is too tired to code any more.

    I spend days with my family and the occasional weekend with small groups of friends for drinks and conversation or drunken Kinect Sports (always amusing). I even enjoy Vegas 3 or 4 times a year, but only for a day or two at a time.

    You extroverts can keep the rat race all to yourselves; I’ll stick with my very happy life as a hermit :)

I was in all the clubs in school and was a cheerleader, etc. I hated all of it. I was probably in my 30’s before I learned to be who I am.

The thought of a party or going out with friends sounds downright boring (and usually is). I think the older we get, the more contemplative and quiet we naturally should be.

I am 57 years old and up until 3 years ago thought there was something wrong with me for wanting to be by myself. Now I know who I am, know I am not the only one in the world like this, and am SO much happier for it. The world needs introverts as well as extroverts.

      Also, I think the first characteristic be “Socially Connected” covers this. You don’t have to be an extrovert to be socially connected. You can be introverted and still have close friends. Maybe not as many and probably not as many casual friends.

    I expect that introverts, provided they get the space they need to withdraw and recharge, are just as happy as extraverts. “Acting like an extravert” is tiring and stressful. I don’t need to act like an extravert…I can enjoy a gathering with friends without having to be the centre of attention, and can enjoy activities like performing a dance on stage without being an extravert. Being social is not owned only by extraverts…they just do it in a different way.

    If you’re introverted, and act extroverted, you’re just acting. And that’s f-ing exhausting. There are times when it’s worth the effort, but I have a hard time believing it would prolong your life. It feels a bit like chronic cardio. Extroverted is one of those things you either are or you aren’t.

    If anything, this list just confirms what I believed previously – long life is genetic. You either have it or you don’t.

I think it’s beneficial for introverts to try to socialize a bit more in a way that works for them, and to try not to internalize everything. Introverts may (not always) need to learn to speak up more and, if necessary, stand up for themselves better if they’re prone to letting people take advantage of them.

It may be less often and on a smaller scale than you’d want for yourself; that doesn’t make us wrong. Acting contrary to one’s nature is exhausting and unhealthy.

        Karen wrote on May 17th, 2013
        • Very well said.

          When extroverts tell introverts to “socialize a bit more” – that just indicates they have absolutely no clue how much socializing that introvert actually needs. I find that extroverts seem to think I’m not happy unless I’m talking to somebody at all times. Actually the opposite is true. If I go to a party and talk to 1-3 people (one-on-one, not in a group, whether I know them or not) I consider it a success. If I don’t talk to anybody, I feel exhausted from the pressure to try to talk to people and failing. If I talk to more than 3 people, I feel absolutely exhausted (usually worse than talking to no one). Don’t try to tell me that something that sucks the life right out of me is healthy.

          The real advice is that people need a social network. The actual size and characteristics of this social network is going to vary by person. In general, introverts require smaller social networks than extroverts. And building that social network does not require an introvert to be or even act extroverted. I find I make friends by listening. It’s something that comes naturally to me. Over a long period of time – with short, scattered conversations – simply listening lets people know that I care and those that appreciate it become my friends. No acting required.

          If there’s anything unhealthy about being introverted, it’s the pressure that our society puts on people to be extroverted. That causes stress. Being alone – but not lonely – doesn’t.

  24. I just wanted to point out that there are some very common misconceptions about introverts and extroverts that I see reflected in this article. Introverts are not necessarily people who don’t enjoy being social. Introversion is not the same as simply being shy. The key factor between introverts and extroverts is whether social situations drain their energy or give them energy. Extroverts need social stimulus more in order to function because it energized them, whereas introverts need times of solitude to recharge. However, many introverts are extremely social creatures, but they need to balance their social expenditures with time alone.

    Pajamazon wrote on May 15th, 2013

      My best friend in the world used to come over every single day after work and spend the entire evening…asleep in the recliner. He’d wake up whenever I wanted to go do and he would come along to keep me company, but mostly he was snoring in the corner. He was a constant, comfortable, reassuring presence in my life and he spared my husband from doing all the “girl stuff” with me. We did that for 18 years until my husband and I moved across country.

I make a real effort to break out of my natural hermit mode on a regular basis, but I find it much harder than my extravert friends to reach out for support when things are going badly. Even something straightforward like asking a waiter about gluten takes an effort of will (& I have Celiac Disease!)

Gluten exposure’s another matter though, & I’ve had to retrain myself to be more assertive… frankly it is much easier not to go out to eat, but that’s actually the kind of social occasion I enjoy most. Oh the irony! :-/

    • I agree with you. I will starve, crawl home from the hospital after having surgery, and sleep on the street before asking anyone for help. Thankfully I developed a thick skin and the ability to survive a lot, but know that takes a toll.

    • I have no trouble asking for help or speaking up, especially when it comes to advocating for myself or my family. It is a skill I have gained as I’ve matured. OTOH, I have to be careful about correcting others…need to remember there are other ways of doing things the “right” way. :-)

      I also like to seek adventure…exploring new places, trying new sports. But still need my alone time to recharge.

  27. Introverts are ruled by the neurotransmitter acetycholine while extroverts use dopamine. This is why extroverts are continually looking for action, it gives them hap hits, go go juice. By the way, introverts are longer lived simply because they do have aversion to risky activities and because it is within their nature to conserve their stores of energy. Marti Olson Laney has some great books on the subject.

  28. It’s interesting that four of the seven characteristics correspond very closely withh the 5-factor theory of personality. I haven’t done any in-depth reading on this theory but I know it broadly breaks down personality into five areas that exist on a continuum.

    Openness to new experiences

    I believe that our personality traits are largely genetic, although they certainly can be influenced by environment, so some of us are largely swimming upstream on some of these characteristics.

  29. Before we further extol the virtues of extroversion as a culture, I highly recommend Susan Cain’s book, “Quiet: The Power of Introverts in a World That Can’t Stop Talking”.

  30. I really need to work on the friendship/family thing. I spend so much time alone (working from home doesn’t help) sometimes I feel like my life is passing me by before I know it. The problem with cultivating friendships in your 30s everyone is already partnered up (friendship wise), married with kids, etc.

    • I work from home too & it would be easy for me to go for months without seeing a soul outside the family other than the grocery store clerk! Some things that help me: a really wonderful book club, classes on various subjects, meet-ups with a learning/sharing focus– in other words anything where the talk doesn’t have to be small. I can engage in conversation for hours if there is actual subject matter, but idle chit-chat exhausts me.

  31. I worked in a nursing home once where there was this liitle 102 year old lady who was wheelchair bound, couldn’t stand and had to be lifted in and out of everything. Yet her mind was completely there. People used to ask her what her secret was, and she always replied “It’s not a secret, it’s a curse.” Just sayin keeping the body fit is just as important as keeping the mind fit! I’m sure everyone on this site knows this. Not sure I’d want a sharp mind without a functional body!

    • I sometimes think that society treats nursing home residents like they have just magically appeared there. There’s a tendency to view it as either just how old age is or a random occurrence, like a car wreck. Or at least I used to, if nothing else. :)

      Unfortunately, if my mother is an indication, there’s quite a few of them who have “earned” their spot there by completely neglecting their health. If there was an opportunity to leave physical work to someone else, she took it. Walking was for chumps.

      Posture and proper gait? I was born this way, you see. Outdoors? Too many bugs, too much uncomfortable weather.

      Food? Forgo the reasonable diet my mother gave me (including offal) and jump on the low-fat bandwagon. It’s fat, not sugar causing all those pesky problems. And now that I’m old and having a hard time, sugar is the only thing that makes my life bearable.

      I’m sure there are some nursing home residents that fall into the car wreck category. Unfortunately, though, they don’t get the blanket “ohh, they’re just old and isn’t life hard?” sympathy looks they used to get from me. My mother of course, thinks I’m just being a heartless daughter because can’t I see she’s old and not feeling well?? Oh, well.

  32. As for the introvert vs. extrovert: not sure there are too many people who are 100% one way or the other…for me, most people would probably consider me an extrovert: always had lots of friends, always laughing, joking, comfy in social situations, but every few days, sitting at home reading in the quiet with nobody but my dog is required to recharge. I suspect that most people are both introvert and extrovert depending on energy levels and where they are in that cycle.

    As for comedy: Bill Burr is my absolute favorite. Very aware of his own absurd thoughts and actions and it makes me aware of my own too, which allows me to laugh largely at myself and really how silly I am – as we all are – about so many things.

    Josh wrote on May 15th, 2013
    • I bet you are more introverted than you think! Needing quiet time to recharge is actually the main defining trait. Intoversion doesn’t equal shyness, though there is certainly some correlation.

      • I’m an outgoing introvert. I am social yet I do not want many people close to me. Tough to explain. I can only give my full energy to a handful of people in my life, so they have to be real menschen. Otherwise I keep a personal barrier. One that does not prohibit new people, conversations, experiences, etc, but one that prevents someone from getting to close. A genuine facade, if it can be called that, (manners?) until I determine if a person is a mensch. Too many people are drains. Uncle Sam provides me with enough taxes in my life so I’d rather not spend time with energy taxing people.

        Paleon Bon Rurgundy wrote on May 15th, 2013
        • I know the feeling. I just read an article on LinkedIn that suggested that inconsistent co-workers/friends are much bigger drain than those that consistently treat you poorly. In other words, Frenemies are a much larger emotional black hole than a plain old enemy.

          I have some Frenemies for relatives and can vouch for the drain. They are, to steal a line from Into the Woods: “Not good, not bad, just ‘nice'”. Unfortunately, I’ve pretty well stopped speaking to one of them but I have no justification for cutting the tie entirely because they are “kind of nice to me sort of”.

          In another case, I think I’ve finally started the process of letting go of the fantasy I had for our relationship. That one was tougher because I wanted to be close to her but it was never reciprocal. In looking back over the years, there’s definitely a mild Frenemy pattern. Mostly friend which is positive but still, ultimately very draining.

  33. Certainly, in the context of successfully adopting Primal Blueprint as a precursor of longevity, “persistent, industrious, organized, and disciplined facets of conscientiousness” are required, along with faith and optimism to deal with the nebulous and imprecise science. This may be particularly true for us aged former endurance-athletes attempting to mitigate years of metallic damage by adopting a Paleo diet and fitness regime, whom initially find that our attempts to adapt to fueling on fat vs carbs invokes cortisol, cortisol, and more cortisol, making the PM utopia elusive.

  36. There is a strong statistical association between regular worship attendance and longevity; one study put the impact at 7 years, approximately the same as not smoking. Various reasons are given that overlap with your list (community, optimism, paying attention, etc.) It is of course difficult to do an interventional study! Also the religious faithful tend to exercise more, use their minds more, smoke and drink less, and take care of each other to a greater extent. A big study from California Public Health (Int J Psychiatry Med 32(1):69-82, 2002, found that infrequent church attenders had higher mortality from most causes, and that the prior health status and associated behaviors did not explain the entire difference.

    Of course students of anthropology know that prehistoric Groks had religious instincts, with burial rituals for their dead.

    A decent house of worship (and there are many) makes it so much easier to get a community than trying to do it yourself!

  37. I’m so glad to hear that laughter made this list. I’m always quick to laugh, and to compound the issue, I listen to podcasts with comedians when I’m not listening to nutritional ones on the go. Laughter might actually be the best medicine, even when it gets you odd looks on the metro or walking down the street laughing by yourself.

  39. I guess I’m one of those introverts who is happy with it. It’s not a disease. I have cultivated ways of interacting that would make you think I was an extrovert, but I’m not, nor do I want to be. Society does favor extroverts. Oh well. Won’t be the first time I’m on the wrong side of what society favors 😛

  40. Mark:

    Great post. I’ve seen in real life that all of these things are keys to longevity. My grandmother practiced all of them and lived to be 96, despite some health limitations that doctors believed wouldn’t allow such a long life.

    Her funeral was attended in large part by people much younger, whom she’d befriended over a long period of time in her community. She was a blast to be around, so people included her, even though she was a little old lady (but just on the outside).

    Stoicism – yes, good idea. Tim Ferriss has covered it well (what it is and how to apply it). I highly recommend having a look.
