Comment of the Week

I’d also have to opt for saving the drowning friend first – it’d be too hard for me to have to try to swim with my mouth stuffed full of chocolate

– That’s my take as well, PrimalGrandma. You’d also risk diluting the chocolate with swallowed water, which would be a real tragedy.

  1. Wow. Just four days in primal conditions makes a marvelous impact on your health. That is exciting news. This gives me a great idea for my next vacation – to really be primal including giving up electronics, traffic noise, artificial light. I look forward to my experiement!

    1. It is great
      I took a week alone in the sanoran dessert in northern Maricopa wilderness and it’s incredible.

  2. Great post. Always look forward to these every Sunday.

    I really like the article about tracking fitness – I’ve always had a hard time with this. I’m not too sure about their methods, but I think it does have some merit. Too many people focusing on the wrong things. I’m going back to school and heard some younger undergrads talking in the hallway about “friending each other on fitbit” and spending HOURS on the elliptical to “one-up” each other.

    …It took me right back to my old college curriculum of chronic cardio. Ugh.

  3. Look into camp grounded.com. Its summer camp for adults that is also a skillshare and tech free.

  4. A lot of interesting articles, thanks Mark!

    The Microdosing LSD link was interesting. I shall not make any comments about my misspent youth in the early 70’s LOL.

  5. Four Days in the Stone Age is very interesting. We should start making time every year to be four days in the forest.

  6. I’m a little concerned with the study To Restore Health, “Do we Have to Go Back to the Future?” The Impact of a 4-Day Paleolithic Lifestyle Change on Human Metabolism – a Pilot Study.
    I don’t know if I’m reading this wrong, but it says CRP was increased “C-reactive protein, as the main indicator for low-grade inflammation, increased up to an average of 169,6 %.” Is this correct? Seems a bit odd.

    1. Yes, that was their finding. The authors speculate:

      “We suppose, that living in the wild stimulates the innate immune system as shown by Qing [52] and Park [53] via activation of proinflammatory pathways in order to anticipate evolutionary old danger signals such as bacteria, viruses, insects or predators.” (p. 13)

    2. Just putting modern people in a national park with no shelter, day or night, is going to drastically increase their stress. That probably increased their inflammation by itself. I know I wouldn’t sleep well in the outdoors with no shelter. Four days of anything is not enough to adapt, so I wouldn’t take the study too seriously. Also, the grammar, sentence structure, and punctuation of the article is so bad it suggests it was not reviewed at all, or was hastily written by non-professionals. I’m certain four days without junk food and with exercise was good for their health, but I discount the inflammation finding.

  7. I think I could watch the tiled roof guy build stuff all day, it’s very soothing AND interesting. Plus, you get to see some awesome barefoot action.

    1. Me too; He made my jaw dropped …. So skilled

      As far as living in the stone age there’s “10,000 BC” from England

      But I find “lynx vilden living wild” most interesting and tempting

  8. The link between healthy food searches in Google and lowered Infant Mortality was very interesting!

    1. The frosting made me smile. But isn’t it only a wealth correlation? I’m not expert on the United-States so I don’t know for sure, but just with all these loans and credit searches, it’s not hard to imagine it like that. It’s also not hard to imagine a link between wealth and infant mortality I guess.

      1. Valid point but there is plenty of poverty in some of those states too. Maybe it’s not wealth but education-related? People raised in a better educational system are more likely to understand the value of trying to eat healthy even on a tight budget.

  9. Wrt/the study about fitness tracking, I think it might have yielded different results if they held constant for a variable of… I dunno – anal retentiveness? I like to track things and since I started working out at the Y, I’ve been keeping an exercise log. It makes me feel like I’m really accomplishing something, not just meandering.

    Are my work-outs ‘fun’? As fun as they were before I started tracking them. I don’t know if I’d call them fun, but they are enjoyable.

    I think I have the soul of an auditor.
