I tend to change ages depending on what situation I'm in.
I change where I am from depending on the situation.
But I am 41
I should've also asked: do you feel like you're part of your generation?
I don't, but as I go through my "What song are you listening to right now?" list, I'm feeling horribly, terribly entrenched in my generation.
Not sure about feeling part of my generation though, my friends are all between minus 15 to plus 10 years my age or so. It was not so strange when people my age where getting married and having kids, but sometimes a bit strange when my much younger friends are now doing it.
As for music, though I have mixed tastes, I do not think I was ever in tune with what ever it was with my generation.
