I hate the word "obese". With as much as 60% of the Americans being fat, you'd wonder why there isn't some sort of law suit against certain institutes, public facilities, theatres, and most of all the airlines. Why? The seats are to small.
Think about this for a second, now there is more fat people than there are skinny. Being embarrassed because of your fat isn't the only problem though. If you don't start losing weight, chances are a lot greater, you'll pay for it in the long run. If you don't have any physical problems that are apparent to you, they may be sneaking up on you.
