In my case, the bicycle doubled as my sporting activity and means of transportation. It has numerous useful effects. After an accident on a bicycle, some people will never get on it again. I had my accident playing football. I remember playing football when I was very young, about 8 years or so. I was the goalie for my team. Rising anxiety as the ball drew closer, I dove in for the ball, and got it, but also got kicked in the throat. I thought I was going to die, and that experience has ever kept me away from football.
