Am I a BabyBoomer?

Talking today with BabyBoomers, set me wondering if I'm a BabyBoomer.
I always thought of myself as a BabyBoomer simply because other terms didn't exist years before GenX!
I was a child of the 60s, so my spirit is of the 60s, but my culture is more of the 70s witnessing Glam Rock and then Punk, as a teenager.
It's true, that 60s Vietnam protests would mean nothing to me as a kid, and living in the UK, even less so.
The Wikipedia definition clouds it for me, being born in '61, but it does make clear that UK Babyboomers are later than USA Babyboomers.
I might be an inbetweeny, having read these definitions, where I carry all the worst traits!
