Replying to Concussions

What concussion stories do you guys have? Have you had many concussions? How did you get them?

I just got major concussion. I was doing skiercorss caught an edge on top of a 40ft jump and flew in the air doing a 540 flat spin landed right on my head.  Right into the nets. Apparently almost jumped an 8m high net and ended up caught in the net.  Everyone thought i'd broken my kneck. But walked away with an almost ruptured lateral ligament (neither of my skiis came off) and a bad concussion. Sucked because did second run and got fastest time but It didn't count.  But was completly fucked the next day and still can't do anything.

What are your stories?
