Or maybe if we keep running we stay young. Either way, I love these:
"You don't stop running because you get old. You get old because you stop running" from Jack Kirk, ninety-six-year-old super-runner, from Christopher McDougall's bestseller Born to Run.
I've been at it over 30 years now. Running through illness, injuries good times and bad. Getting up in the morning to go running is like breathing for me. My day just doesn't feel right unless I've started it with a run.
