When I was a kid I did gymnastics. Not for very long, only a few years but long enough to master the splits. I remember my gym teachers making a big deal about it -- how I was only 9 years old and could do the splits, but the 16 year olds who had been working on it their entire lives still hadn't mastered it. It certainly didn't seem like a very big deal to me. It's not like it was hard.
