Yes,Yes,NO
Yes I have fallen off my bike when I was younger but not since then
As I remember I was still learning to ride a bike and my friend had a bmx bike and I just couldn't ride it and kept falling off, and one time went over the handlebars.
Eventually I sussed how to ride the bike
and when my brother bought his racer we used to ride it up and down our road. The racer was huge and my feet would just about reach the pedals, to get on I would tilt the bike to one side, put my leg over and push the pedal down to move off and then ride the bike. It was good fun until you had to stop, I would have to fall to one side.
Luckily I did have nay major injuries just scrapes and cuts.
I have been cycling to work for about 18 months and always wear a helmet.
I was reading about T E Lawrence on wikipedia and read that he died in a motorcycle accident and the doctor who treated researched that head injuries were the major of cause of motorcycle accidents, this led me to make a decision that I should wear a helmet.
Also I think lights and high viz jackets should be born as drivers just can't see us cyclists, I know because sometimes when I'm driving I don't see cyclists, now I make sure that I'm mor3e aware of them.
