I can't really speak for the whole world, but for the countries I have visited and the one I reside in, I feel nowadays when I go for my evening walk I see fewer kids in the playground, or adults socializing.
Last year I was at my peak of discipline, waking up at 4am to go lift before school, dedicating myself to boxing and spending hours in the boxing gym and going on runs each night, all while doing good in school and keeping all A’s in honors and AP’s.
