As I think of it, most of the things I checked off I did when I was in my 20s. Some of it, the substances in particular, was done in high school.
Things like going to see a porno in a theatre, subscribing to a porn magazine, or playing Twister naked with cooking oil - yeah, like Slowpoke said, that's pretty outdated. I last saw advertisements for porn in theatre when I was still in grade school. Maybe it varies by region.
