Apologies if this is boring. I thought......If tons of miles at high intensity are bad for you, Tour de France riders would show those affects
Actually, quite the opposite. Much lower morbidity. 6.3 years longer life (French riders). An international stud showed 7.8 years!!!
Considering all the drugs they took, this is an eyeopener for me.
(My heart stops when I sleep, apparently, this is the only thing I have in common with TdF riders, pretty common with those old dogs, too)
