I rode dirt bikes for awhile without much incident. But my very first time on the road, I put a brand new Harley Nightster (my mom's) into a guard rail doing 35. 13 stitches on my side, lacerated my kidney, bruised my lung, broke my 12th rib. Was in the hospital for a week coughing up blood, getting trashed on morphine and calling my girlfriend by my ex's name (oops), knockin' over urinals... About a week before my doctor said my rib could handle it, I was back on the road on my own bike that I had someone else pick up for me in the month or so I was couch bound.
Before I started riding, I had been to a couple fatal accidents and a couple more really terrible non-fatal accidents. Motorcycle vs. moose, motorcycle vs. car, motorcycle vs. inanimate object.
The possibility is scary, but the idea of not doing something I want to do, because of the possibility of getting hurt is there, is ridiculous to me. You can get in an accident in a car, a bicycle, a snowmobile, a canoe. Get old enough, you can get in an accident just standing up. Or hell, laying down in bed. You could be 22 year old and have a heart attack in your sleep.
What, me worry?
