re: Check in if you have a bad knee, bad back, or other bad joint

Horrible knees,and a shot throwing shoulder/arm from baseball, lower back was thrown out by deadlifting, ankles are tattered from rolling them too many times in basketball, and as of recent neck problems have developed. Due to all of this I've been seeing chiropractors and physical therapist for about a year and a half now. I'm in my mid twenties. I'm so fricked when I hit 40.
