Declivity: a downward slope or bend (descent, decline, fall).
As in, “Twentysomethings often view their older counterparts as total fuddy duddies who have taken a ride down the declivity of fun. In response, thirtysomethings just chuckle because they know how great life is once you’re neither poor, tired, subsisting on frozen meals or hungover all the time.”
Inspired by this series, I decided to use declivity to create an infographic exploration of the details of life in your twenties versus life in your thirties (click the photo to see it in full glory). Oh, and the differences between party activities? True story. Like “Go Ask Alice” for thirtysomethings.
