Help. Where can I find people like me?

I'm female. 52. Enjoy the same music as my 15 year old son (fave artistes are Chipmunk, Dizzee Rascal and Tinchy Strider). I also love horror, super hero, action and Sci Fi movies. I like converse, DM's, boyfriend jeans and retro tee shirts. I have nothing in common with people my age as I have no interest in their music, fashion sense or what the call entertainment.
