Why does no one go out anymore?

When I was in my late teens/early 20s pubs and clubs were everywhere and always rammed on a weekend, nowadays they're all closing down and half-dead. All my mates wanna do these days is sit in and drink/have a smoke, going to the pub is like a once-a-month thing now and clubbing basically never happens anymore 🙄. I moved towns recently and thought I might meet some lads my age by going out a few times, but it's always half-empty and full of old people. Honestly I should've been around in the 90s, those raves sounded awesome 😂. Seriously though, what gives?
