Thanks for this link, Lori. It further confirms my belief in the anti-inflammatory effects of exercise. I derived additional proof from my recent experience with a local orthopedic doctor. I've sported a right knee prosthetic for going on two decades. When two years ago my left knee began to ache, I thought, "Uh oh, time for a second prosthetic." But no, I've managed to moderate and practically eliminate the ache through regular exercise. My doctor tells me he believes I've succeeded in not needing another total knee replacement thanks to consistent exercise. So, you see, I'm a great believer in exercising through pain, at least through reasonable pain.
