10 Interesting Predictors of Longevity

10 Interesting Predictors of Longevity FinalThis isn’t a Homeric epic. There are no oracles laying out our destiny and predicting our inevitable demise. But even if we can’t know the precise date of our death, we can use certain biomarkers, measurements, and characteristics to make predictions—with a reasonable amount of accuracy—about a person’s propensity to kick the bucket.

As is the case with any observational data, these predictors may not be malleable. And if they are malleable, actively changing them won’t necessarily confer the longevity they’re associated with. Getting plastic surgery to appear younger probably won’t make you live any longer. But they do tell a story. They suggest the qualities, activities, behaviors, and exercise patterns that may, if maintained, lead to a better, longer life. At the very worst, walking a bit more briskly and gaining some lean muscle won’t hurt you, and it will very likely help you.

So let’s take a look at ten of the most interesting predictors of longevity:

1. Handgrip strength.

You know your grandpa with the vice grip for a handshake? Or that old lady who simply would not give up her hold on those plush towels last Black Friday at the Walmart despite you yanking her around like a rag doll? They’ll probably live a long time.

In middle-aged and elderly people, grip strength consistently predicts mortality risk from all causes. It’s even better than blood pressure. In older disabled women, grip strength predicts all-cause mortality, even when controlling for disease status, inflammatory load, depression, nutritional status, and inactivity. Poor grip strength is even an independent risk factor for type 2 diabetes across all ethnicities.

2. Walking speed.

A few years ago, a study of over 7000 male and 31,000 female recreational walkers found that walking intensity predicted mortality risk. Those who walked the fastest tended to die the least. Now, don’t think you can consciously speed walk your way past a hundred. Researchers in the study were looking at the natural walking speed of frequent walkers. What the study tracked and linked to lifespan was the natural walking speed of the participants. They had no idea they’d be graded.

A more recent study found that rapid declines in walking speed also predicted death. Some clinicians find so much value in walking speed that they even use it as a “sixth vital sign.”

3. Facial appearance.

Several studies indicate that the perceived “age of the face” is a better predictor of mortality risk than objective health markers, actual age, or cognitive function. More objective measurements of aesthetic age, like wrinkling in areas unexposed to the sun, also predict longevity.

4. Subjective opinion of one’s quality of life.

If you’re happy with your physical and psychological health, social relationships, and your immediate environment, you may live longer. Having a poor opinion of your current lot in life may have the opposite effect. Even when those subjective opinions are compared to objective measurements of your health, your relationships, and your environment, subjective outlook is a better predictor of lifespan.

5. Muscle.

I’ve always said that lean muscle mass is a metabolic reservoir for healthy aging. Skeletal muscle produces important proteins and metabolites that regulate recovery from trauma and injury. The more you have, the better you’ll recover from surgeries, burns, falls, breaks, punctures, and damage. The more muscle you start with, the more you can spare to wasting and the better you’ll bounce back from bed rest and other forms of forced inactivity. Expression of klotho, the “longevity protein,” is even strongly dependent on the strength of one’s skeletal muscle.

6. Life purpose.

The popular notion that being driven to achieve your goals increases wear and tear on the body and destroys your health seems right. You’re sacrificing sleep for work, neglecting loved ones, choosing work over exercise, eating junk food instead of cooking. What does the evidence actually say? It turns out that having something to live for helps you live longer with a lower disease burden. Life purpose predicts allostatic load, another way of saying “age-related wear and tear.”

This was a little surprising. We often think of the hard-working entrepreneur burning the candle at both ends, falling apart at the seams, health suffering just to pursue and achieve the goals. But the actual evidence refutes this.

7. Intelligence.

Intelligent people live longer. Across any and all causes of mortality, having a higher IQ confers protection.

Some point to the quicker reaction times that also accompany higher IQs. If you’re smarter, you’ll probably have an extra fraction of a second to swerve out of the big rig’s path and avoid a fatal collision. This is certainly part of it, but a faster reaction time can’t explain the protection intelligence confers against all-cause mortality.

Others attribute the all-encompassing protection to the intelligent decisions, healthy behaviors, and prudent practices smart people make and follow (PDF). The smarter you are, the less likely you are to smoke, not exercise, or think fast food is okay to eat for dinner every day of the week.

8. White blood cell count.

White blood cells, or leukocytes, are the primary agents of our immune system. They battle pathogens, infections, and foreign invaders. Many diseases are associated with white blood cell deficiencies, so it seems like healthier, longer-lived people would have high leukocyte counts. Right?

No. Actually, leukocyte counts on the lower end of normal predict longevity. That only seems to be true in healthy men and women. It’s unlikely to persist in unhealthy or immunocompromised populations who actually need the white blood cells to stave off causes of. In the healthy folks, a low-normal WBC count indicates a low disease burden.

9. Autophagy.

Autophagy is cellular maintenance. It’s how our cells recycle waste material, eliminate inefficiencies, and repair themselves. It’s required to maintain muscle mass as we age, and inhibiting it induces age-related atrophy of adult skeletal muscle. It reduces the negative effects of aging and reduces the incidence and progression of aging-related diseases. In fact, researchers have determined that autophagy is the essential aspect of the anti-aging mechanism of fasting. “Aging” only occurs when cellular autophagy fails, or reduces. People who live past 100 have higher levels of the primary autophagy biomarker, meaning their cells are maintaining themselves longer and retarding the aging process.

This is something you can directly control. Fasting, ketosis, caloric restriction, exercise, and dietary polyphenols all trigger autophagy, and they’re all likely to improve longevity.

10. How much broccoli and Indian food you eat.

I’m kind of kidding, but not really. Maybe the most important anti-aging pathway in the body is Nrf2. Activating Nrf2 unleashes many antioxidant pathways, increases glutathione, and has been shown to trigger the “anti-aging phenotype” in animal studies. Foods in the brassica family, which includes broccoli, kale, cabbage, cauliflower, and Brussels sprouts, all contain sulforaphane, a potent Nrf2 activator. Another Nrf2 activator is curcumin, found in turmeric, the primary spice in Indian curries.

If I’m being safe, these are merely descriptive. People who already have these attributes, biomarkers, and tendencies are more likely to live longer than those who do not. But if I’m engaging in educated speculation, many are also prescriptive. Lifting weights, going for walks, finding a life purpose, improving your day-to-day quality of life, eating more antioxidant-rich food (including broccoli and turmeric), triggering autophagy through fasting or occasional bouts of caloric restriction and ketosis—these are all good, healthy practices that should pay off.

What do you think, folks? Can you think of any interesting longevity predictors not mentioned today? Which of these are you already implementing?

  3. I would add epigenetic momentum to the longevity list also! I’ve seen some older family members smoke like chimney’s and eat crap for 50 years and some died in their 90’s. Their mothers and fathers, and their mothers and fathers must of had some good habits and genes. This momentum can only last so long. I think as a species we are getting weaker and hope that we can reverse this with diets and habits like Primal and Paleo.

    • There’s a difference between living long and feeling good and being healthy and living a long time and constantly fighting health issues. I know a few people that have lived into their 90’s, but were on several medications, inflamed, and plaque with arthritis, diabetes, digestive problems, and the list continues. That’s no way to live. Great article. The key for me is to constantly assess how I am feeling and to try to prevent things because prevention is easier than repair!

      • That’s what I’m thinking, as well. The strong grip made me think of my great aunt, who wouldn’t let go, physically or spiritually. She died ancient, but after years of dementia. If it were possible to choose, I’d happily say ciaociao a good twenty years earlier, and go out like a light.

  5. I don’t particularly want to live to be over a hundred since it usually means outliving all of one’s family and friends. That said, I love really good Indian food. We have an excellent Indian restaurant nearby and enjoy their lunch buffet on a regular basis. I usually pass up the naan bread but love their chicken curry and various combinations of fresh veggies and spices.

  7. Interesting, I would think meditation (or prayer) plays a role too. Monks in Asia are consistently living to be quite old, a good majority reach and breach 100. Scientist have determined you use more alpha waves during meditation or prayer. So if your religious keep that praying up, of course meditation is accessible to anyone, religious or not.

  9. One study showed women who had their last child at age 33 or older were more likely to live longer. I had my last 3 weeks before my 31st birthday so we’ll see if that’s close enough!

    I’ve got some of these things on my side and some good longevity genes (like my 91yo grandmother and her husband who lived very well to 85-both avid walkers) along with some other grandparents and my mother who all passed away in their 60s.

  13. What if you’ve never had a life purpose? I’ve been searching for 35 years and have never had a calling. I can tell you it’s the most depressing thing on the planet to know you have no purpose.

    Jon wrote on March 16th, 2016
    • Of course you have a purpose! It’s the same for everyone! Your main purpose is to follow Christ and “therefore go and make disciples…” (Mathew 28:19) You must be talking about a side-purpose such as a specific field of interest, or a talent or a hobby you think you should have, like teaching, writing, art, music or gardening or something like that. Don’t sweat the small stuff. Focus on your main purpose. Study and learn about the gospel of Christ. You’d probably be better at it than most since you don’t seem to have other interests that need your attention at the moment. Look up Ray Comfort at wayofthemaster.com. That’ll get you going in the right direction for starters.

        • Never said that about aetheists… Only said what everyone’s main purpose is, certainly not that everyone follows Christ let alone goes and makes disciples. And those with a reprobate mind will usually find something else to do that’s pleasing to themselves, a secondary purpose, so to speak. But here’s a thought… The gospel of Christ in one word (IMHO) is propitiation. Has anyone ever done more for you than Christ?

          DJ wrote on March 16th, 2016
        • I see this all the time on here – as soon as someone mentions believing in god…. c’mon now. I am not religious myself, but the teachings of Christ make sense to me: Be peaceful and loving towards others? Don’t be greedy? Be of service to others? Uh, ya – those are GOOD things… things that have definetely given purpose to MY life…nothing wrong with learning more about how to be good humans…. which is of course, the basis for all religion IMO. You can be an athiest but still demonstrate respect for others and not call their god an “imaginary friend” just sayin’.

          My fellow non-believers, let’s all try and be less defensive, shall we?

          KariVery wrote on March 17th, 2016
      • Agreed, DJ, and it doesn’t have to happen in a church.
        A calling doesn’t have to be something big or “important” by the standard of today. Rescue a homeless animal, anonymously pay for someones dinner at a restaurant, or visit the ones everyone else has forgotten in a nursing home. Or combine a) and c) and adopt the right pet and have them trained so they can accompany you to said nursing homes. Win, win, win situation. I figure if a certain deed makes me happy, the person or animal in question that needs a friend happy, and my God happy, what harm can it do?

        Ziva wrote on March 16th, 2016
        • The Christ message of loving your neighbor, taking care of children, having charity towards the poor and dispossessed, turning the other cheek, not being judgmental–are all terrific objectives that we all should strive for. This is true of everyone, despite the behaviors of many self-professed Christians. But the whole idea of “believe in me and you go to heaven regardless of your good works” just makes no sense at all. So you certainly don’t have to be a Christian to have a purpose in life. That said, I strongly believe that behaviors that follow the exhortation to “love thy neighbor” are highly adaptive for our species, and are the most enlightened set of behaviors we can adopt. Adopting these behaviors can constitute the purposeful life well led without any church or dogma at all!

          Tim wrote on March 18th, 2016
      • I have a very close friend who is an athiest. She knows what I believe, and I know what she (doesn’t) believe but we don’t let it get in the way of our friendship. I don’t spend our time together telling her she’s going to Hell, and she doesn’t spend her referring to something (which she knows is very important to me) as an imaginary friend, or the invisible man in the sky. Mutual respect and tolerance goes a long, long way.

    • I know, right? Most folks just go by waist alone and it really drives me nuts…. Hello! I’m 6’4″. So what if I have a 36″ waist? Its called common sense. I have a six pack and my BMI is 26.5 but I’M at risk and I get fussed at by my doctor. I’ve actually spoken to plenty of physicians who are so stuck in their ways that they think waist only is good enough, and actually site the only study I have been able to find showing that waist only was equal to height waist ratio. Of course, there are several indicating otherwise.

      Maybe I should start eating less protein, lifting less heavy things, eating more carbs, and running marathons again.

  17. After reading Woodford Monte’s book, While Science Sleeps, I suspect one of the top predictors is methanol intake and how you manage methanol toxicity: regular low-dose ethanol is highly protective. He makes an overwhelmingly strong case that methanol is one of the most critical modern toxins.

    Another input is polyunsaturated fat intake; keeping this down to 3% of calories will improve longevity.

    And of course, both of these inputs affect skin aging.

  31. Thanks for this great article, Mark! With regard to eating less (fasting, calorie-restriction, etc.) it is nice to be reminded that it IS OKAY to not be eating all the time.

    I get a lot of subtle pressure from family and friends to eat. Let me just say that after losing 100 pounds in 18 months, they think I’m a few fries short of a Happy Meal when I fast. I guess it makes them uncomfortable if I don’t eat every time they do. Our society is so fixated on socializing through the consumption of food, I’m often made to feel unsociable (whether intentionally or not) when I don’t join in. No wonder we as a nation are so obese. We’ve been brainwashed to think we need to eat at least 3 meals and 2 snacks a day, or we need to eat in order to celebrate or even casually socialize, that celebrating or socializing without food is somehow insulting.

    It seems like so much of our daily lives are consumed with when to eat, what to eat, who to eat with, and purchasing/preparing for all that eating… think what we could accomplish in our lives if that time was spent in more worthy pursuits (like walking).

    So thanks for being one of the few to say, yeah, try NOT eating for a little while. How refreshing. :-)

    Kikie wrote on March 16th, 2016
    • Great response. Might I also say that the “food is love” argument has also had a big impact on obesity rates. So many of my family and friends get so offended when I turn down their offerings of food because they equate food, especially junk food, with their love for me. Food is an “easy” gift to show you care, so people take it personally when you say “no” to their cooking or their offer to take you out to a restaurant to eat. Mothers are especially adept at making their offspring feel ashamed for rejecting their food. It is sad, but we need to help our loved ones show us their love for us in ways that don’t include meals, like taking walks, creating art together, visiting museums, etc.

Well Tyrell did set him free, didn’t he? Not with his science or “biohacks” to mess with Roy’s body. Tyrell set him free spiritually – “Revel in your time.”

    Isn’t that really the answer here – to maximize the quality of our life, not its quantity?

  36. Yea, isolated stories don’t mean much but I am going to tell it anyway…. in the 90s I moved, got a new neighbor, a man in his 60s, a mechanic in fact. One of the first things I noticed was he had extremely poor grip strength (couldn’t tighten with a tool what I could do with my fingers.) Even his wife could easily open jars he could not. He’s still alive so grip strength did not predict his mortality however… he went downhill fast, fell and broke ankles, later would fall and couldn’t get up, couldn’t walk more than an hundred feet, went into the nursing home early and has been horizontal since… and kept alive several times but timely drug intervention. His overall dysfunction was certainly heralded by his horribly poor grip strength.

  37. I would think remaining sexually active later in life may be a factor for longevity?

  38. I think there is a big difference between a life purpose and working crazy to meet goals.
    The guy sacrificing to climb the Corp ladder to get more money or a title is far different than the nurse who isnt just putting in time but truly feels she/he is there to give her patients the best treatment she can give. I know who I would put my money on.

    • Agreed.

      Life purpose and ambition are two very different things.

  39. I totally believe these, especially the walking one. There was a time when my walking pace had slowed to a crawl. It drove my poor patient husband nuts when he was out with me or we took a walk. After years of working on nutrition and my thyroid (diet, supplements, NDT), I found it natural and easy to walk at a good pace again.

    The walking wasn’t the cause of poor health for me; it was a sign of what turned out to be massive chronic fatigue caused by seriously bad thyroid and adrenal health …the *ability* to walk at a quick pace is a great marker of health.

  40. Need to get to work on a few of those. In particular the Idian food. Great list!
