I think they can be associated with numbing oneself, but aren't necessarily. I would also associate most of those things with vivacity, exploration, spontaneity, and risk taking. Perhaps there is also a shift in the dominant narrative of associated with these activities. Studies seem to show the youth mental health is at an all time low. I wont go as far as to claim that lack of drinking and fucking is the cause, but I do think they are related, perhaps as the result of a third factor. I don't have data to support this, but my gut tells me the root may be more reserved and cautious approach to life in general.
