I'm sure someone else has said this or will eventually but it's much worse to fall up the stairs.
My sister managed to get halfway up the stairs via-falling and no she wasn't drunk.
The thing with falling upstairs is one - it's much more embarrassing since you'd practically just manged to do something so stupid it defies several laws of physics making it look like you almost tried to do it - meaning you look like you deserved it and any pain it brings.
Falling up the stairs sucks
