Well, I hope *my* little posts weren't interpreted as negative or lacking support. I truly didn't mean them that way!
When I was young, the medical schools
pretty much didn't even consider you if you were older than 30. Also you had to demonstrate that your entire life had been point toward being a doctor. Now... Not so much.
My aunt had been a SAHM for a long LONG time. She was a microbiologist (PhD) before she married and had kids. In a very interesting (to me) mid-life crisis, she divorced, estranged herself from her kids (which has nothing to do with the rest of it, really) and went to medical school!! She was close to 50 at the time. She changed her name (first and last) and has been a practicing psychiatrist... actually just retired.
So. There you have it. I've heard of people of even more advanced age getting into (and through!) medical school.
I can see how people who had been nurses would make great doctors!
