I work at a teaching hospital and the young interns and residents all look like Dugie Howser to me; very young . . . but I'm 58, married and very boring to my younger female colleagues. But, I do see the young, single, 20-something RN's looking the attractive McDreamy type intern/residents, up and down. And, one time, one of the young doc's-in-training did ask me, if one of my female colleagues was "seeing anyone". Hey, nothing surprising about it, just raging hormones!!
But, so far as I know, (my wife tells me I'm pretty dense about these things), there aren't any flaming romances between staff.
