I'm pretty tough I think. If I'm in a fight, angry, or something like that, I'm in the zone and won't be bothered at all. I'd say I have a pretty high tolerance to pain otherwise too.
Read the post above about being scared of riding a bike. Here are some horror stories for you. Between like 8 and 12 I always road my bike and stuff all time. When I got a new bike when I was like 8, I was riding full speed up and down the block and when I was going back to my driveway, full speed, my brother who had also got a new bike comes flying out and I crash into the side of his bike. It was with the force of a regular car accident almost I think. I went FLYING like 10 feet luckily onto some grass. I did like a flip in the air and landed on my back. Had some scraps I guess but fine. I was My brother was balling his head off but wasn't really hurt. Had some scraps but was lucky I didn't literally hit him and not the bike. I thought it was "cool".
Another time, a couple years later, I had some plastic ramp. My brothers most used it but the first time I tried, full speed again, I must of did something wrong and the ramped slipped or something and I fell off the bike mid-air and landed flat on my back on the concrete with the bike following partly me missing my head luckily. It was a heavy bike too. My back was really scraped up and so were my elbows. Banged my head pretty hard too. Didn't really hurt I guess. All the kids watching thought I was going to really hurt but I just got up and walked to the house to clean off. It ached I guess. Banging my head part is what bothered me the most. I was pretty shaken up from it since the bike almost fell right on my face. My daredevil days were over after that.
