When does one become "too old" for things?

Ok, I have 1200 watts driving two 12” woofers and another 600 driving four mids in my car. I really like my sound system and I enjoy music of all types, but especially heavy bass and drums. I have CD’s that I downloaded from itunes and mixed myself specifically for this quality and I like to play them really loud. Loud enough that I can feel it in my chest.
My mother has accused me of acting like a child because of this. She tells me I need to grow up and act my age. I honestly don’t know that I’ll ever not enjoy music loud and rough.
I turn it down when I come into my neighborhood so the neighbors don’t have to hear it but on the road I crank it. So, how old do you have to be? Is there a point when you are too old to listen to it loud and get off on it? Do I need to snap out of it and take up church socials?
