Not ashamed to say it here (I'm 50), but I decided to stop being so open about it at work (when I'm working again) because a couple of years ago when I was 47 - 48, it scared some of my younger co-workers. They'd been treating me as a peer (which I wanted - as in, hey, we're all adults here) and it unnerved them to realize I was old enough (or almost, in the case of the early thirtysomethings) to be their mother. Teens all think I'm a senior citizen, though, so go figure.
