I hadn't fully thought of it that way...I'll concede the point. I was partially joking on that count anyway; I find it tragic that people aren't well enough educated to be able to do something which, to me, is ridiculously simple. I dunno. And it is certainly the case that too often, doctors and nurses are too busy to be able to help everyone as much as they might need (not to imply anything disparaging on the doctors and nurses - quite the contrary, they are very overworked from what little I've seen in my visits to hospitals and the like...)
