I'm concerned that people are either surprised or unaware of a lot of facts. Not limited to, but also not restricted from, the AH OC.
Yes, fast food is not entirely 'healthy' food. Sort of like smoking is physically addictive. You shouldn't have to be told it, it should be common sense from emperical evidence.
Fast food is inexpensive and....well, 'fast'. You don't have to cook it, just wait in a relatively short line.
On the whole, American's neither excercise enough nor eat the proper foods (see food pyramid).
America is a relatively wealthy country. Fast food is plentiful, fast, and inexpensive. Americans are not forced to hard labor in order to survive. Americans are also complacent about excercise. Surprise, surprise...most Americans are fat.
Side note: It's not really McD's fault and it's sad that some parents tried to sue McD's because their kids were fat. They were the parents who are in charge of what their kids ate, they drove them or provided McD's meals, they provided the money, and they probably allowed their kids to stay inside and play video games or watch movies instead of getting enough excercise.
Sadly, I think it's a cultural thing. Sort of like a rocket when the fuel runs out, the rockets momentum will still carry it up for a while but it will eventually slow, stop, and start to fall.
I honestly think that America's fuel is running out or already has. It's just a matter of time before we also lose momentum and start to fall. Some say that it already has.
