Then I imagine your wife knows a few doctors who she   

"Sonders (sic) how they ever got into medical school."

She never talks about that. Her medical school declines the vast majority of applicants so the graduates are very select group.

I never met any of her classmates who were not impressive once one knew them better than casual acquaintence.

Do you know what you call a US Army officer? Sir. I can tell you that some of them are whack jobs, some are truly space cadets and some do not inspire respect. 'Band of Brothers' Dick Winters said it best- "You're not saluting the man, you're saluting the rank".

Yes, some physicians, like some of any group, are not the sharpest knives in the drawer but they earned the title.
