Hi, I maintain the world's biggest spread sheet of life span experiments. I believe slowing aging can increase life span. It turns out that the effect of exercise on all-cause mortality is well studied. My big spread sheet summarizes about 80 experiments. They show that exercise usually lets us live longer. A histogram of their results is at http://morse.kiwi.nz/kingsley/lib/exe/fetch.php?cache=&media=science:histogram_of_exercise_vs_all_cause_mortality.png I think the trick is to not OVER train. I'm told that over-training is worse than no training, and just working up a light sweat is good. More findings from data mining my big spread sheet of life span experiments are at http://morse.kiwi.nz/kingsley/doku.php?id=science:kingsleys_big_spread_sheet_of_life_span_experiments
