Honestly most people have a change in things as they age.

I used to go to concerts quite a bit from 16-25. Local shows, arena concerts, outdoor festivals... but you would have a hard time dragging me to one these days. Too expensive, too crowded, too much hassle, sometimes too loud depending on situation

I slowed down around 26-32.. Last heavy metal show in the pits was lamb of God and the Last few Arena shows I saw I greatly preferred the "stands" over the GA floor. Think it was Iron Maiden. It's just easier... I can just walk out the hall if I gotta pee or grab a beer and not wade or fight through bodies.

Nowadays, I can see/hear pretty much anything I want via streaming services/YouTube at my own convenience.

There's certainly the 'live spirit' to experience at a solid show with like minded people but the expense, crowd, hassle, and well...sweaty people... Just aren't something I care to deal with.

It's not the only thing I've had a change of interest in and I'm sure it won't be anywhere near the last.

I think that's true for all people. We grow out of interests to one degree or another our whole life.
