On the subject of knee pain. I'm 48, have never really jogged consistently. I bought a treadmill for a treadmill desk. At first walking was a bit painful when walking more than an hour a day. Now, after a couple months, I not longer have pain when walking even a few hours. In fact, it feels better to walk than to stand. And now walking doesn't create knee or leg pain, I am starting to jog. At first once every 2 or 3 days. Now about nearly every day for 20-30 minutes. Though if I feel worn out, I'll skip a day to avoid any injuries. i try to jog outside, but when it's too cold, i jog inside on the treadmill, while watching queued youtube vids.
