Meet Mark

Let me introduce myself. My name is Mark Sisson. I’m 63 years young. I live and work in Malibu, California. In a past life I was a professional marathoner and triathlete. Now my life goal is to help 100 million people get healthy. I started this blog in 2006 to empower people to take full responsibility for their own health and enjoyment of life by investigating, discussing, and critically rethinking everything we’ve assumed to be true about health and wellness...

Podcast I just appeared on: The Feel Good Effect, where I talked about thriving, repairing, and restoring.

I bet this explains some of those vitamin D studies that got poor results: Magnesium deficiency makes vitamin D ineffective.

I can never pass up a good haka: This one was to honor a favored high school teacher’s passing.

So do I: “We believe it is implausible that each sex, age, and ethnic group, with massive differences in life experience and attitudes, had a simultaneous decline in willpower related to healthy nutrition or exercise.”

That was funny! “I like my nuts dry roasted”. I got a little chuckle from that. . was wondering if anyone else would think the same way I did! Hee hee!

– I have no idea what you’re implying, Tiny Tina.

Whatever happened to the idea (pretty sure I heard it here a few years back) about replacing saline with coconut water?

Still amazed by how much ‘research’ is required to convince people of common sense (re: standing, bending, exercising throughout the course of one’s life…)

I’m with you Alisa…crazy that we need studies to prove things that just seem like common sense to me. But even crazier still that people don’t listen to this stuff. I know an older woman who is now confined to a wheel chair simply because she lost her strength (especially quad strength) due to sitting around doing nothing. She is mentally sharp but stuck in a nursing home dependent on others to take care of her. So sad.

That is very sad and possibly unnecessary. She can get out of that wheel chair if she wants to unless there’s something physiologically wrong with her that gives her no choice. Are you close enough to her or her family that you could encourage whey protein drinks to help build up her muscles? (It’s supposedly very helpful for older people, and most nursing home food isn’t very nutritious.) She should also start walking a little at a time, even if she needs to use a cane or a walker and can’t do much more than just stand up at first.… Read more »

Shary, thanks for all the great ideas. Many of them have been suggested to her and she was doing PT for awhile. But I think she’s just content where she is.

My grandmother lived to be 104 and even though she was in a wheelchair the last few years still at least tried to get up and walk every day. So much of it is your attitude.

I see this with my own family members. They one day say “I don’t understand why I can no longer do X”, but they have done absolutely no movement or muscle exercises in decades! It’s a shame, but in my experience it’s not lack of knowledge but just lack of desire. Laziness and apathy. My 68 year old father can no longer get up from a chair without significant use from his arms and yet he thinks nothing of it. He loves to remind me how strong his “core” is from all his crunches…

it’s hard and makes no sense but we have to let them live their lives and be happy in there own way. I was reminded of this answering an ad and walking into absolutely deplorable living conditions. My happiness may not make my new friend happy.

Great article on the 6 million yo human footprints. One great thing about the internet, is to bypass the gatekeepers and bring change about much quicker. I see this on various scientific fronts, the most obvious would be nutrition, where the paleo, primal, anti-low fat paradigm has spread much quicker. The harder the gatekeepers try to hold on, the faster they will fall.

That is a very good point. There was the Scarsdale Diet, and somewhere the Weston A Price Foundation was toiling away in obscurity, but the Lipid Hypothesis had a lock on public perception until there was a way to promulgate its problems. The Ancestral Movement owes a lot to the internet.

Look up what Dr. Jolie Bookspan has to say about bending. She does not like bending even at the hip, she advises squating instead (OK, it may be impossible in a flooded rice field, but in most other situations it can be done easily once you get used to it).

I like to do a mix. I squat down for anything that requires being bent over for an extended period of time, but hip hinge for picking up things or things like brushing my teeth or washing my hands at the bathroom sink.

That magnesium / vitamin D article references an Osteopathic journal.

What is wrong with that?

So implausible! Mid 70’s on the chart, hmmm, that would be about the time that the FDA started their higher carb lower fat recommendations heart heath ideas, wouldn’t it?

Re the skin bacteria and skin cancer article. Are researchers going to speak about how to maintain that bacteria on your skin? Or study people who wash too much/use antibacterial creams, etc. vs. those who do things that help the bacteria and skin cancer rates? Are there certain oils we can put on our skin that actually feed and help them?
