stuff snipped

I also taught officially for several years, and now teach unofficially
in many ways.

And I can do what I teach - or in some cases I used to be able.

There's the rub. Age changes the equation, but come on guys, it's a
platitude or a homily or something like that. I've forgotten! (-: Anyway
it's not meant to be literally true and it's more a dig against critics than
teachers.
