Seriously, Americans in general are getting to be fat. I spend 8 hours a day sitting at a desk typing on a computer or talking on a phone, then I go home and read a book or get on the computer. Eating habits don't help, since I at least always feel like eating out at work just to get out of the office. I'm not a fatty but I've definitely put on more weight than I needed to; or, rather, it's all around my midsection instead of somewhere useful.
Fortunately my next apartment complex is going to have a gym and I'm going to force myself to use the thing, if only so I can also use the pool without being embarassed.
