Lazy Americans

Yes Im an american, but something Ive been seeing lately is seriously starting to annoy me. Its these people all over my college campus with their rolling bags. Is it THAT hard to actually carry the bag? Most of the people i see doing it are overweight, wouldnt it help them burn off some calories if they carried the bag? I can understand for those people with back problems or other health related issues but I know that most of them are just being lazy. Seems like everywhere i look on campus people are wheeling their bags around nowadays. What do you guys think? Is it happening in your area?

Thanks
