I've been on 4chan daily since 2005. I'm realising part of the reason I still post is to cling on to the glory days of my youth.
Your mid-30s is kind of cruel when you have lots of responsibilities: job, house, pets, kids, wife, aging parents etc and sometimes it's nice to dive into boards and remember the good old days when you'd fap several times a night, play vidya with friends, and read visual novels and play 2hu. Maybe I can quit for real this time.
