  1. Been following the Oregonian guy who pulled a 350 lb. sled (at least at the start) 1,500 km to the south pole. SOLO. Great story.

  2. Was hoping gelatin was involved in the development of a decellularized extracellular matrix–based biomaterial scaffold for the purpose of foreskin reconstruction in circumcised males.

  3. I occasionally use CBD oil as a sleep aid, but that’s about it. My sister used it for anxiety attacks.

  4. Having read the Dark Horse path to happiness article I realise that, with my craft projects, I enjoy the process but am not interested in the finished piece. Now I need to find someone who enjoys framing cross stitch pictures and sewing up knitted items !

  5. Hi Mark,

    What exactly are you doing in the new link photo? Dancing? Hacky Sack?

  6. Circumcision is sexual assault. Prosecute. If you ask 5,000 in tact men if they want to be circumcised 4,999 say no. It is clearly being forced on them. When given a choice men resoundingly reject the mutilation. My body. My choice. End of argument.

  7. Indian medical student kicked out of college by racist white professors for questioning their SJW beliefs

    Kieran Ravi Bhattacharya was a medical student at the University of Virginia and he has been kicked out after having questioned his white college professor’s SJW beliefs.

    Here is the audio of the lecture where he questioned his professor’s SJW beliefs:


    He speaks from 28:45 to 34:00

    Here is the audio of the suspension hearing:


    Here is a picture of the people who were at the suspension hearing:


    Notice how 14 out of the 16 people at that suspension hearing are white people. If this is not an act of racism against a sincere indian medical student, then I don’t know what is. Look at their smug arrogant faces as they kick him out for DARING to question their SJW beliefs.

    His twitter handle is kieranravib if you want to ask him questions or set up an interview with him

    1. There are plenty of sites where you can argue about things like this, my friend. It is completely off-topic here.

  8. The ‘dark horse’ approach to happiness sounds a lot like the old idea of “Eudaimonia”, the concept the founders apparently had in mind when they wrote we had the right to “the pursuit of happiness”.

  9. Boerge Ousland crossed the Antarktis in the 90 thies.
    He walked from the shore to shore, more than the double distanse .
    To claim he is best is an insult!

    1. He used skis and rigged a kite assist in his journey. He was the first to cross solo, yes – but he did not walk. It does not detract from his accomplishment to laud a different accomplishment…

      1. Sorry – posted before I corrected 🙂 Boerge Ousland traveled unsupported but not unassisted (his kite is assistance). O’Brady traveled unsupported and unassisted. But my undersyanding is that O’Brady learned from the trips others, like Ousland, room before him.

  10. We used some cool technology to keep our baby’s foreskin.
    It was a complicated and controversial procedure called Please Don’t Cut My Kid’s Penis.

  11. Hi, Mark! Merry Christmas and Happy New Year! I am enjoying reading this blog post. I have read The Dark Horse Path to Happiness too and I think many people will be inspired by this article. Xoxo.

  12. Really enjoyed the article about the ‘dark horse’ under interesting blog posts and hope I can follow a similar route myself with my love for running, health, nutrition and exercise. If I’m lucky maybe I can have becoming a pro athlete as my main pursuit whilst trying to grow my own blog!


    Would really appreciate it if anyone could give my blog a look and give feedback! Your content is amazing Mark, please keep it up!

  13. If a genetic allele predisposes a person to both ED and T2D that doesn’t really suggest that by preventing one through lifestyle behaviors they will prevent the other;

    A –> (/increases risk of) B and A –> C. If no (/reduced risk of) B, then no C is a logically flawed argument, especially in this case when there is no information to suggest that the lifestyle behaviors induce epigenetic changes specific to that gene.

  14. Kudos to those Italian scientists. I always thought “circumcision” was wrong. It shouldn’t be allowed, in my opinion, until the person’s a legal adult and have insisted. Religion doesn’t have the right. When are they going to get with the facts (they have “female genital mutilation”) and call “circumcision” (a “barbaric ritual” as Kramer and others call it) “male genital mutilation. It’s an atrocity to inflict on someone.
