I admit I was joking a bit about the "getting older" and "taking longer" part. Had I played more extensively with gmail earlier, I would have switched right when it was possible to keep your domain, which I think has only been possible for a few months now. So I think a lack of knowledge about gmail played a bigger role than age. To the extent that adapting to new contexts is a reflection of "age", I am a very young person. (After using gmail for 1 day with my startup's streamfocus.com domain, I switched my whole architectural firm over)

As far as the age issue, in the sense that you're talking about, I've met many 20 somethings who acted "older" than me. I have always been a risk taker, an optimist, a person constantly learning to improve, and many people aren't. This is not an age issue, but an outlook on life issue.
