I have always wondered how people ride a bicycle, for me it was impossible skill to tackle... At the end I learned how to do it, as long as I can go straight and not make any turns :D
And why on Earth would anyone do it? It's uncomfortable and unsafe :P
Crazy people...
Riding bicycle is super fun. You don't really have to take much risk by riding around hairpin bends. Though once you master it, it becomes more fun.
