Just How Long Did Grok Live, Really? – Part 2

November 3, 2010

Speculation on ancestral lifespan is fun and potentially illuminating, but I think examining living, albeit imperfect, examples of modern hunter-gatherers offers greater insight. Sure, the environment has changed, wild food sources have shrunk in diversity and availability, and modern civilization has encroached and meddled and disrupted, but the few remaining hunter-gatherer populations exhibiting relatively untouched traditional lifestyles represent the most promising window into what life actually looked like and how long it lasted for our ancestors. Luckily, a couple of researchers – Gurven and Kaplan – had the bright idea to look at ethnographic studies on actual, living HG populations and analyze the available data on actual lifespan and mortality therein. They found some interesting stuff.

This study (PDF) has been floating around for a while. Readers have sent it to me on several occasions, and I believe it’s been mentioned in other bits of the online ether (blog comments, etc). […]

First, I want to say thank you for convincing me to do Tabata! I was struggling to lose weight and Finally I found something that helped! I really appreciate your coaching! - Craig T.

Ever since I was convinced to do Tabata I have seen huge results, I lost 6 pounds and gained energy in the first 3 weeks. I have been working out for 3 months before I decided to do Tabata and I struggled to lose weight. At first I thought "How am I losing weight by bringing my heart rate up then cooling down then bringing it up again?" I don’t know how it works but it does! Thank you!! - Theresa F.

The first day of Tabata, I wondered WHAT AM I DOING - I AM 56 !! Five weeks later I knew that it was what I needed. I learned that I could push myself well beyond my comfort zone and feel good later. I have a marked improvement in physical as well as emotional endurance. - Lyn C.

When I was first told about Tabata I was very excited from the word go, however that excitement stemmed from the fact that I had no clue what it meant. I missed the first week of class b/c I was traveling for work so when I came in during the 2nd week I had some making it up to do. It was hard at first b/c my body wasn't used to working out at such a fast pace, but once I got into a rhythm I started to feel very good. These classes are no joke. If you stick with it you will leave there feeling stronger, healthier and overall better about yourself and what you've accomplished. I would recommend these classes to anyone. Darrin is a great trainer and he'll keep you going with his energy. - Jami L.
