I am an old man

Well, judging from a few comments the past couple of days seemingly I am an old man. First I get to hear from a 20-something woman that I look good for my age. Actually, I thought this woman was more like 30 but a comment like that?!? Who wants to hear they look good for their age? I wanna hear "you look good". Period. Then on a phone conference today, where the speaker was on, I was mistaken for a man. Hello? Ok, so I don't have a girlie voice, but still... And why is it that one remembers these non-compliments much better than the real compliments??
