Yep, Got knocked off a scafold and toasted my back, that's what got me started. Bought my first computer and the cat jumped on the keyboard the day  got internet and a piece of artwork poped up with a reference to R'sity. Got poser to help keep my mind off of the pain. It helped.

Blew my knee out, again, this time playing football, instead of hockey, last game of the season. Ended up spending a lot of time doing CG to keep my mind off of it.

Now the heart and stroke thing, Lost the feeling in half my left hand. I'm relearning to play my guitar left handed and still doing the CG.

Moral? Do things that keeps you happy and your mind off the bad stuff. There are lots of programs for workouts during rehab from injuries. All the athletes I have known have had some form of injury and still managed to stay pretty fit.

all the best.
