When things are going well, I exercise a lot.
When I exercise a lot, things go well.
These are not mere coincidences. When things are going well, I exercise a lot, and I feel great, which means I look at least halfway decent (or, as I now hear so often “good for my age”*) and people sometimes say to me, admiringly, “Wow. You exercise a lot. You must really enjoy it.”
Heh. No. I do not “enjoy” exercise.
