Riding bicycle - as a skill is awkward and fascinating. It was established at very old times and so has remained. Imagine bicycles were invented today, its a product that nobody would buy. It takes lot of learning, falling, injuries, and for a lay person it looks awkward and risky.

If we generalize this, we are missing out on some skills, which are awkward but which our bodies and nervous system can learn? but perhaps we are not trying to learn thinking its risky?
