Huh? How are laws of physics even remotely related to a kid learning any adult profession?

I'll rephrase my previous comment: because being a notary is a protected profession in most country, it's hard (probably impossible) for a kid to become a successful notary.

Sometimes "hard" means "other people make it hard". It doesn't mean that it's hard in the sense that you have to discover new things or go to other worlds or be able to read binary code fluently while it's scrolling down the screen, Matrix-style :-)

Then I misunderstood your point. You are only impressed by something a child does if it's impossible?
