The next big one for me is 60 (though its more than a year away). However since I refuse to grow up it doesn't really make a difference. I still fancy women in their 20's, though older women now have more appeal. The guitars I like are still from the 50's, 60's & 70's really, as are the amps, even though I have newer stuff. I still go to lots of concerts, but prefer to have a seat rather than standing and I also perfer to have a hotel room rather than camping! Other than that I have much shorter hair which is greyer and thinner but mentally I am still stuck in my 20's. Getting older doesn't scare me as much as growing up does!
