I’ve noticed two big differences in how I approach concerts than I did when I was younger.
I no longer feel the need or desire to be in the crush around the stage. Hell, I’m willing to pAy a bit extra to get seats away from the floor.
Ear pro. I remember boasting of being slightly deaf to my dad after he picked me up from a Faith No More concert. I was stupid back then.
I’m sure there are more, but those were the two that stuck out at me.
