Born to run: genetic test can reveal those best able to run marathons“[T]o run a marathon in a good time requires the right combination of genes and that nearly a fifth of the population lack this special mix. For runners with the right genes, it means their bodies can quickly adapt to carry large amounts of oxygen to their muscles, allowing them to run faster and for longer. Those who lack these genes, however, will never improve, no matter how much they train, and their performance may even get worse the harder they push themselves.”

  1. re – Born to run: genetic test can reveal those best able to run marathons –

    Just an anecdote, but my daughter’s best friend was a so-so middle distance runner in high school with poor training and so-so coaching. She had no scholarship offers (naturally) so was a walk-on at University of Tennessee (our state). UT just happened, by sheer chance, to have one of the best 800 meter coaches in the country. Naturally he was skeptical of this girl’s potential, so he had her run a trial 800, which she did with a so-so time (around 2:15 or 2:20 I think, maybe slower — under 2:05 is competitive). Anyway, right after she ran he drew blood and analyzed it for (I think) lactic acid levels. When he saw the results he started dancing up and down. My daughter’s friend went on to run the fastest time in NCAA history and is now a professional sponsored by Nike. Conclusion: he may not have identified the genotype but he sure recognized the phenotype. The potential was obvious way before the actual performance.

    I would amend that slightly: if it enhances my group’s survival in the long-run.

  6. The study found that women who took off their bras for good experienced a 7mm lift in their nipples each year they didn’t wear a bra. Researchers also found that bra-less women developed firmer breasts and saw their stretch marks fade.

    7mm a year X 30 years = 210mm

    What does 8.27 inches of “lift” do to womens’ nipples?
    Does that means they move up to their shoulders?

  7. I love the study on how texters are shallow and also claims ethnic prejudice is equivalent with rating minorities negatively. I bet those researchers text a lot.

  8. About the bra study, it seems like it was a correlational study. He compared women who wear bras to those who don’t. Now those two groups can’t be comparable, seriously? Instantly I wondered if he even controlled for breast size in the study. Obviously larger breasts would sag more…

  9. Leaving earth. Because we love our own children, and grandchildren tend to be young and cute, plus liking the culture we inherited (and fool ourselves into thinking still exists), we extrapolate that people in our general tribe, or even mankind as a whole, will be people we approve of and hope will carry on. For many generations

    Of the great-grandparents I can make a guess about their values, only half would approve of me. None might approve of my brother or most of my cousins. Why the hell do we think that people a thousand years from now are going to be a good deal for the universe? We might hate ‘most everyone a hundred years out.

    If HBD folk can’t step back and be objective about this – and they apparently can’t, as this perpetuation idea seems unquestioned and universal – who the hell is going to? Why do even we get starry-eyed about the prospect, as if only the best of us is going to make it through and spread joy throughout the cosmos?

  10. Thanks for the shout-out!

    Well, it’s objectively true, if you measure by ecological footprint. I also think there are too many people on the planet, at least for its current technological level. That does not mean I want to commit suicide. To the contrary, it just makes me all the more motivated to be prepared for global economic and/or socio-political collapse.

    h*ll i hate most of ’em now! (present company excepted of course! (^_^) )

    that is very insightful, avi. something on which to ruminate. (something else to keep me awake at night, thankuverymuch! (~_^) )

    ah ha! always pays to read the fine print.

    i figured the whole research project was just an excuse for some frenchmen to “study” some breasts … over the course of 15 years! nice work if you can get it! (~_^)

    I’d refuse it. It will get old in, like, 2 days maybe. Then I’ll have to watch them slowly sag for years on end. No fun.
