I like to stay in shape so I can pull off my nice clothing and hairstyle on a regular basis. Well that and so I can have self worth and make others envy my ability to do every day things like climb on top of things and at work, run around with kids rather than sit on a bench and scowl at others who run around having fun. It may not be your style, and it wasn't my style for years either, but dressing nicely is as beneficial socially as being fit. Props are an important part of our lives whether we want them to be or not. Dressing nice, like having a DUFF has opened doors for me and gotten me more attention, which upped m confidence after already getting a boost from being in shape. I have a lot more confidence to talk to a group of peers or a woman I find attractive when I know I'm dressed in a way that will get a more positive response in a similar way that a moderately attractive person would feel better hitting on someone when they're the most attractive person in the group.
