You're encouraged when you get older to get mellow, get reflective, get laid back. I don't understand why. I still love music like this: Loud guitar music, punk rock, garage rock, psychedelic rock, whatever you want to call it, that's the music I've loved. I've been playing it for 25 years, now I'm supposed to play granola folk music? That doesn't make sense to me.
