Go ask around the medical community and you’ll discover quite a few didn’t handle it well. Kids don’t do a good job of washing.

I have, and this isn't true. it's also not supported by the medical documentation available. Instructing kids, especially when you start from an early age, to develop proper hygiene habits is pretty easy. I've even borne witness to it many times personally, although I'm not necessarily offering my personal experience as proof.

It’s highly relevant

not when you're making claims about everyone everywhere. what matters there is evidence to back up your claims, which you have yet to provide.

so, since you were the one who initially made such claims... please back them up from reliable sources such as the AMA, for example.
