No, it's people's individual poor decisions which does. It might not be politically correct to say, but it is nonetheless true.
In the end, that is what it comes down to. But i don't believe its that simple...Burger King now has video games with the "king" eating whoppers and what not that they sell for $3.99 for Play station...What do you think kids will want to eat when they play that game? In Most "hoods" in the states, you have gun shops and Booze stores at every other corner...Their is some serious mind control going on with these types of things...Why commericals are so effective...But you are right, it does come down to poor decisions...But for the uneducated on the topic of Health, a poor decision probably is all they have been taught...
