As others have pointed out, there are many factors that contribute to high cost healthcare. And while I think that BMI is almost completely worthless, and I've never been really fat, I can say that exercise and losing weight are some of the best things (and best feeling things) I've ever done. Sure, fix the costs (especially with IT/technology in general, as those on this board can probably have the biggest effect on that), fix the insurance industry, and let's have a serious look at the food industry while were at it - but on an individual level, giving exercise a try will probably reduce our health costs in the long run and make us feel better in the short run.
