It's a matter of greed, really. "Oh just one more-- just one more-- just one more--" leads to obesity just because they don't know when to put the burger down.

Given, I'm not in the best of shape (very far from obesity though, thank you very much), I know when enough is enough. McDonalds is great when you go there occasionally (say, once every 2 months or so?) instead of multiple times a week.

Also, this so-called 'epidemic' is made worse because most Americans are lazy to the extreme, as well. Again, I'll admit that I don't work out or anything, and I'm not very physically active, but that's mainly because I just don't find the time. Once I'm out of school and have the day to myself, I plan on getting an hour and a half a day of exercise.

To me, obesity isn't an epidemic. It is just a side effect of the severe 'greed-stupidity-laziness' epidemic, which is the real problem.

On a side note, I love McDonalds' double cheeseburgers. :3
