I read this infoworld article yesterday called "Age gap hampers technology adoption". I've always felt younger than I am and this article confirmed it for me :-) It talks about the tension between those under 35 who are embracing the new technology (e.g. Web 2.0) and those over 45 that don't. They say

The older group is showing apprehension around Web 2.0 fueled by how quickly the technology is changing.

Who are these guys? Hello, McFly, where have you been for the last 12 years? What part about the internet and "rapid change" don't you get?

Anyway, I'm feeling not a day over 30.
