Ah oops. I kind of assumed that most people learn at least those two, and some others - an introductory bit of ball room dancing is typically part of the primary school (government school) curriculum here!

How fascinating -- that would absolutely not be a given over here (UK). Though it's been a while since I was at school ...

I wonder what other assumptions we all have about what other people had as part of their "physical education" curriculums in schools?
