Let's not forget the mono sodium glutamate that McD's uses in many of it's products. also known as MSG. It has been shown that MSG actually can be a step on teh road to obesity! go figure. the glutamate industry folks are up in arms about that though....

anyway, they aren't going out of business anytime soon.
People don't wanna make a meal for themselves it seems.

It would seem that humans in general are innately lazy. The conditions of survival weigh heavy on whether or not we are active or not. But put us into a western society where not much effort is required to survive and watch us get lazier and lazier.

Face it, the whole machine is a bit of a weird thing. The meek have inherited the earth, natural selection is not really applicable in a lot of ways anymore except for teh worst cases of genetic mutation. But frequently, the "weak" do better than the "strong" in our new societies. I wonder what kind of effect that is going to have after 1000 years or so.

I would say that earth stands a chance of being a real quiet planet eventually.
