An Australian study involving 1000 people has concluded that people who regularly go to festivals / raves / concerts are happier with their lives overall than those who don't. Basically, the survey reports that people who went to any sort of communal musical event said they were pretty satisfied with their lot, on a bigger scale than those who didn't.
Officially, the study says that it "explores the connection between habitual music engagement and subjective wellbeing," where 'habitual music engagement' might be anything from attending music festivals to just going to the club. The most important part of the experience, however, is supposedly the communal element, the part where you feel joy among others feeling joy, and essentially experience the best bit of being human. So yeah, kinda makes sense that if you're doing that more frequently, you'll likely be doing okay.
We might not be scientists here at Techno Moves, but we'd recommend going out to test this "theory" for yourself. Go out and have a dance with your mates. It's worth it.
