concussion first season, didn't have a helmet and was racing my sister down a green (I could do WAAY better than that). Skidded on some ice, hit my head, and blacked out.
Crossed Tips, Hit a rock, and did a frontflip, tweaked my knee a little but I can still ski.
Caught and edge doing a 3, ended up doing a misty 90 and landing on my ass. Hurt so much I pulled the muscle in between your pelvis and crotch.
