I'm sure I've told y'all the story about seeing my English prof naked while I was an undergrad, didn't I? I happened to have a summer school PE class that begin at such a time that I arrived to dress out just as she was finishing her routine morning swim. The first time I discovered this, not only was she completely naked except for a towel (on her hair), she called out to me and we had a conversation.
She is by far the oldest person I've ever seen nude. I never even saw my grandmothers naked when I was a little kid; they were both pretty modest. I've seen my mom naked a lot, but she's not really what I consider "old." My English prof, however, was at the very least in her late 70s, possibly early 80s.
She was petite and old-lady thin, like Estelle Getty, very spry and in good health (obviously, since she swam laps every morning), but not somebody I'd really want to glimpse in the buff. But the way she was totally not weird about it made an impression on me -- being an impressionable college student and all -- and I think realizing (as Smells did) that most people don't look as bad as you'd expect made me less self-conscious about my own nudity in situations where it's expected.
Bosses are different from college professors, though.
