If you want to enjoy pizza, you'll get obese and die.
If you want to enjoy French fries with salt, you'll clog your arteries and die of a heart attack.
If you want to enjoy chocolate, you'll get diabetes and die.

Seriously, I think these health advertisements won't be happy unless we're eating plastic bags too >.<

No, but your digestive system is going to be seriously strained when attempting to digest plastic.
I doubt your intestines will thank you either.
