  1. I’ve been taking a macular supplement that contains lutein, trans-zeaxanthin, and meso-zeaxanthin, glad to know it may be helping my brain and lord knows I need all the help with that organ I can get. 🙂

    The state of our water supply is a huge concern, looks like we come up with one solution to remove BPA from our water supply, which is awesome, but now we have to come up with solutions to remove the replacements for BPA, a bit discouraging.

    1. I have retinitis pigmasosa and was wondering if that supplement helps?

    2. I also heard about a report that indicated that our water supply is also contains more and more estrogen, primarily due to the increased use of birth control tablets, which find their way into the water supply – I need to research the truth to this report. testosterone levels have halved for men in the last 20 years, and at this rate will will end up self-destructing.

  2. First of all, thanks for the shoutout:) Couldn’t be more thrilled with the Primal Health Coach program…love everything about it! And the piece by Melody Schoenfeld (about vegans) was so right on. As a former vegetarian/vegan who now feels amazing living a primal lifestyle, I agree that we all need to get along! Oh and Mel Joulwan’s coleslaw recipe sounds great, but I am way too lazy to make my own mayo now that I can just order it from Primal Kitchen!

  3. Fundamentals of Aging… got to the profanity and stopped reading. Writers should not assume puking 8th grade profanity on people is just fine because it’s the internet. It’s uncivil and inconsiderate. If you’re mouth is in the gutter so is your brain. Not interested.

    1. It’s unfortunate you allowed your pearl-clutching to keep you from reading and considering some profound and interesting information. Especially considering the swear word was quoted from a poem by Robert Conquest, who himself was paraphrasing Shakespeare.

    2. “Robert Conquest, a historian of Soviet Russia and a poet, once summarized Shakespeare’s 28-line poem, The Seven Ages of Man,’ in five lines.”

      Gratuitous profanity is one thing but sometimes within context it can be used to make a point. The author of the article introduces us to Leonard Hayflick, a famous gerontologists who postulates that a tremendous amount of money and effort is spent on trying to correct the symptoms of disease and aging rather than identifying the source causes.

      You could contact Robert Conquest and let him know you were offended by his intended-to-be-humorous offering, but he died in 2015.

    3. In principle I agree with Tuba. Anyone who can’t keep from spewing profanity in order to make a point is seriously in need of expanding their vocabulary. I’m not interested in reading that sort of thing either. The article in question, however, was actually not that bad. I’ve seen much worse.

  4. I was actually having a discussion with someone over Twitter the other day about running shorter distances versus 5k and higher. My general sentiment is similar to Mark’s. I would much rather have a fast 1 mile run as opposed to working on longer distances.

    My reasons are two-fold. First, it’s easier on the joints. Second, if something is really going to chase me for over a mile, then I’ll just stand and fight. No point dying AND being exhausted.

  5. Ok this is off topic but I wanted to say this somewhere, here are the things I dislike in Primal lifestyle:
    The barefoot thing is exaggerated (but I like to walk barefoot in the grass every once in a while to get this connection with the earth- isn’t called earthling or something like that?)
    The stand-up desk, no. I sit and I move regularly. The PB stance on this has evolved by the way.
    The low carb aspect: I eat bread and plenty of carbs every day (rice, potatoes, wheat flour based things) and I love it, low carb just makes me feel so bad
    There is too much emphasis on animal protein honestly, in real life it can be unhealthy
    The ‘skipping breakfast is fine’, personally I now eat big breakfast (similar to a lunch or a dinner) with carbs and I love it, in the vein of the 30 grams within 30 minutes of waking up by Tim ferriss. It kills any sugar cravings during the day, it makes my mood more constant and it makes me well sleep at night
    The Chronic Cardio, the problem is that it led me to stop cardio altogether. And I love easy non intensive cardio, which I call frunning (free running) lol, and it makes me so happy, brightens my mood, makes me more energetic and sleep at night better
    I love lentils and beans and they make me feel full and make me feel really like a better me lol
    Ok those are the drawbacks of Primal in my opinion. I’ll tell you about the positives one day and there is plenty of them. You are an amazing source of knowledge and you have changed my life. I work for the pharma industry, so insiders are spreading your message and that’s how you’ve changed and are changing a flawed and deadly conventional wisdom paradigm. Keep on doing your thing because we are changing the minds of the influencers and CW defenders. I’m French and I want to influence our government to adopt the PB principle for our health policies. Please meet President Macron to explain him what France should do, I think he will listen.
