The people within your “age bubble” definitely continues to grow until you are roughly in your mid 40s. But then it really does just drop off hard and fast after that. There’s things you can do that also cause it to swing wildly.
Move to Boston - it’s the largest concentration of 20 year olds in the world per capita. Nobody exists over the age of 30 until you are 5 suburbs out of town. So if you are under 30 you just artificially spiked your age bubble up to probably your lifetime peak. If you are over 30 you just prematurely fell off a people my age cliff.
Move to Florida - dead opposite problem.
I dunno. I got a plex lifetime pass 13 years ago in college and setup Usenet with sab, sickbeard and couch potato. Aside from moving to sonarr, radarr 8 or so years ago I’ve never needed to think about it. Currently sitting at 36TB of content. Maybe I’ll move to jellyfin but ¯\(ツ)/¯
Before that I was on DC++ and IRC and honestly haven’t needed torrents in my stack since I was in middle school back in the early aughts
