Sure some people go grind on people's butts at night clubs and take drugs and do DDR in large dark rooms, but people don't just wholesomely dance as a matter-of-fact cultural thing in the West anymore. For centuries royalty and peasants alike had their own dances for socialization and recreation, with the exception of a few extremist religious groups.
Up until disco in the 70s, or at least up until the dances of the 60s, average people danced, young and old, whether it was strictly ballroom, the foxtrot, a waltz, the twist, or the Charleston. I notice this because I like to dance and grew up taking theatrical dance like ballet and tap, and also even took a shag class in middle school. My great aunt taught me to Charleston, and my grandfathers wife taught me some 50s and 60s style dancing.
Dude people are fuckin fat and depressed. Music is negative, angry, and depressing for a disturbing segment of it and totally fuckin un-danceable.
I believe the two things are connected. The loss of uplifting music that had dance steps accompanying it signifies the downfall of Western civilization.
I have decided I will marry a man who isn't afraid to learn how to dance. Marmie needs a nice hobby when she's old.
