Belly fat would be a poor measurement of a lot of powerlifters fitness as well.

The article seems to be mixing up "fitness" and "chance of death", which, while they are related, are probably not as directly correlated as they seem to be in the article.

Yes, the article seems to take liberties from the two studies it quotes.

But I also am skeptical of the underlying studies. So many factors in mortality rate I'm having a hard time believing they were able to control for all of those (weight, age, diet, exercise, family history, etc) and isolate "positive thinking."
