Jesus, sounds like some of you guys need to drink some milk or something. I've taken some hard spills biking, skiing, and doing other shit but god damn.
For me:
Maybe a concussion or 2. Fell riding bike once and landed directly on my head and broke the helmet. Took me a minute to gather my bearings but I was alright. Another time I got creamed in football and had no idea where I was. That was fun.
Pinched a nerve in my back playing football. Never been right since.
Manage to just about cut off a finger tuning the disk brakes on my bike. That wasn't fun.
Broke a finger playing football. (smashes in between 2 helmets)
Sprained ankle playing basketball.
Fell snowboarding when I was a kid at my house and had something stab me in the hand. Doctor had to pull parts of my glove out of my hand. Was pretty nasty.
Other than that a bunch of stitches, a lot of bruises, and lots of road rash.
