How old were you when you first crashed your bike into a tree and knocked yourself out and had to go to the hospital for a neck x-ray?

never happened.

laid a Honda 600RR down once when I hit pea gravel in a sharp turn, skidded about 40-50ft down a field, but was wearing full leathers so no big deal (unlike some idiots that ride while wearing shorts, sandals, and a tank top...)
