I was pleasantly surprised to find that applications by 17/18 year olds to medical school here in the UK require that you demonstrate manual dexterity - one person sending in a video of them plaiting their hair which apparently went down well!

[NB This is in addition to the very high academic standards that are required for places at medical school].

The problem with this is that dexterity beyond a certain level is very specific to what has been trained.

I have a friend who is an eye surgeon. I'm definitely better at playing guitar and piano than him, probably equal at things like juggling and card tricks, but absolutely inferior when it comes to cutting people's eyeballs apart.

It doesn't invalidate your point completely, but just because someone is good at plaiting hair doesn't mean they'll be good at surgery!
