All girls have to worry about their boobies sagging unless they’ve got silicon pumpin’ underneath their skin or are the cleavage equivalent of an ice rink (i.e. smooth and flat, don’t make me explain everything please I have things to do and places to be too). Well either lucky or unlucky for your girlfriend, whether or not your boobs sag and how they sag is largely dependent on her genes. So if her mom’s lookin’ perky at 55, chances are your girlfriend will be golden for years to come. But if she’s not looking so hot? Eh…there’s plenty of fish in the sea, right?
