Staying Out All Night Becomes Less Common
In Your Twenties: Bring on the all-nighters. Whether it's dancing with your girlfriends or a grown-up slumber party, late nights are the norm.

In Your Thirties: Staying up all night starts to take its toll, and, quite honestly, you like being able to function during the day. Instead of partying all night, you call it quits at a reasonable hour and enjoy the rest of the night on the couch cuddled up with your partner.
