I play a lot of music with folks older than me... I'm 37, and the drummer in a blues band I play with is 73 (he's a neat guy- he was in the 13th Floor Elevators).

I've played with folks in their late 80s, and most of the folks I play with weekly in a large jazz band are between 50 and 70. I also play bi-weekly with an orchestra with members ranging from 12-82.

Maybe I lack the same perspective I lacked when I was younger (and thought that 45 was pretty old), but I absolutely don't see how 60 is old. 80 is old, maybe, but 60 just isn't that old, and I don't mean that in the attitude sense, as with:

"The ones that love me say I'm really young, and I appreciate that. I think they mean my thinking is flexible, and I'm excited about the future, like a young person might be."
