For those who answered, "yes" to sports-related injuries, would you go back and do anything differently knowing what you know now?
In sports, I've dislocated both shoulders (football, volleyball, basketball, martial arts), torn my ACL (basketball), had pain from a ganglion in my wrist (shot putting), Osgood-Schlatters (that still hurts, probably exacerbated by basketball ages 12-15), broken literally half my toes (martial arts), sprained ankles (basketball, tennis), dislocated rib (martial arts), back muscular issues (martial arts), hip issues (martial arts), and bumps, bruises, scrapes and abrasions too numerous to remember.
Something always hurts, and I'm 34. Looking back on it, I don't see any way that I would have chosen to do anything differently. I enjoy physical sports, and I don't see that I could have done anything with less intensity. The alternative to this, is a less active me -- I tried that and ended up 65 pounds heavier.
