No, I think it's healthy to grow. I listen to a lot more electronic music than I did ten years ago...and I really get sick of hearing any music that was only a decade ago. Like for example I got really effing irritated with people who "brought back the 90's" too fast during the 00's...with the exception of a few of my favorite artists who I always loved. No, I don't want to hear something a lot that I heard as recently as ten years ago. Like pop music from the late 90's still kind of irks me, because it wasn't as long ago as it should be.
I think it's healthy to appreciate a variety of music and art and things.
I mean I don't get hardcore old-school Si doms who say things like "well I didn't grow up with that." I know this guy who is an Si dom, I swear, he's about fifty - and he won't even eat much Asian or Mexican food because he grew up on the Eastern side of Canada. It's too "strange" for him. He looks askance at me when I cook for him and suggest he might enjoy warm tortillas with his eggs and chorizo.
I don't get it. I feel like my personality continued forming and shaping up through my twenties and now my thirties. I absorbed a lot of SouthWestern culture (Latino elements, for example) during the six years I lived in Vegas with my ex. I didn't even realize until I returned to West Virginia how much it had become a part of me, and how it feels more comfortable to me now to be back out West in Southern California.
I've always liked culture, though. One pervading interest I've had throughout life is culture: music, art, film, dance, theatre, language, cuisine. It's pretty much defined my life and I'll explore culture in whatever direction seems interesting to me at that time in my life, whether it's Russia or Argentina or France.
I think it's the same kind of thing, really.
Of course I'll always have things that kind of "define" me, though, I think. Like how I've read certain books or seen certain films over and over again.
What would be truly odd for me would be if I suddenly became wildly interested in American football. Now that would be strange.
