This. It is very simple. People feel their best in their late teens / early twenties. So they create best attachments to everything they saw / did / listened to during that time.. Nothing in this world can make a older person develop a similar liking to things later on. You can embrace a new style. I did (Jazz). But you can not have that same fire as in your late teens / early twenties. Also because of that. Once our taste is set in stone. Everything we do later on is somehow influenced by that. I liked jazzy pop in the eighties. Little wonder I like Jazz. I make music myself. We were talking about "Always On My Mind" by Pet Shop Boys today with my wife. My wife said. She prefers the Elvis version. But I was 14 back then. I had Pet Shop Boys on a tape. I heard them where ever I went. I still love that corny 80es synth sound. Which was ground breaking back then. My wife (ten years younger than me), not so much.. Nothing in this world short of traumatic brain injury can wipe that memory from me. Sadly this is also true for PTSD. Our traumas become entwined around our personality. The earlier a trauma happens, the harder it is to overcome. Now get off my lawn!
