Handle on Things

So, people born before me, like in the 70s, think they have more a handle on things like Mary Poppins but don't give their kids that same world thinking they "did 1." that they found something that was unnecessary and never bothered going into anything, at all, like the children in the, like, mid 60s.

Problem

Do you know anyone older who had their big start, so-to-speak, as a tween?
