More on everything you've heard

My general philosophy is skepticism, particularly with regard to claims about health practices. Every claim is either right, wrong, or unproven. That's a simplification, of course, because some things can be partially right, partially wrong, and partially unproven. But to simplify the argument, I'm going to ignore that. I do not take action on unproven health claims, for the most part.

Today's N.Y. Times has a nice article on conventional wisdom about running and how it isn't exactly right. The conventional wisdom is that the best temperature is 55 degrees and the best weather is overcast. Also, drink plenty of fluids because you are more likely to cramp up if you are dehydrated. Turns out the optimal temperature is lower, and for elite runners, a rise in temperature has an extremely minor effect. Also, it turns out that dehydration has nothing to do with muscle cramping, and it also has nothing to do with another common problem of collapsing at the end of races. (I doubt being dehydrated is good for you, but it doesn't have anything to do with the problems normally ascribed to it in running.)

I really wish newspapers covered such science more frequently.

    Turns out my insurance is cut off at midnight tonight, not the end of the month. In a way, that's a good thing. Now I'll move my appointment…

    A week off, but tomorrow I head to the home office for a week there.
