Too much exercise won’t kill you.
Quite the opposite.
Tour de France riders live six years longer than the general population.
Sub-four-minute milers, five.
Olympic endurance athletes, three on average.
Cancer deaths down 44%. Heart disease down 33%. Respiratory deaths down 72%.
There’s no ceiling.
No point where exercise stops helping and starts hurting.
The risk doesn’t bend back.
It just keeps going.
There is no point at which you’ve done too much.
The body adapts to almost anything you ask of it.
So why does the idea persist that exercise is bad for you?
Because we find stories in the data that aren’t there.
Stories are comforting. We share the ones that suit us.
The stories point to atrial fibrillation.
Irregular heart rhythm.
Data shows endurance athletes get more of it.
But most older adults have it too.
We just don’t measure it in everyone else.
But AF in a fit 70-year-old is a footnote.
AF in an unfit one is a warning.
So be careful of the stories.
Because the years are real.
They’re yours.
