Air quality. I grew up in the Los Angeles basin in the 70s and 80s and remember having to stay inside because the smog was so bad - Stage 2 smog alerts, they were called. Apparently they haven't had one of those since 1988. Haven't had a stage one smog alert since 2003.
Food, man. Food is so much better than it was in 1986. All of it. Poor-people food, restaurant food, fresh food, frozen food. Food is just a hell of a lot better.
