^ i don't think it's as severe as we'll all be dying out in the close future but we can't just blame mcdonald's and co for people getting fatter (which also happens to be an increase in laziness ie instead of cooking people would rather drive and buy a big mac raking the same amount of time it would take to make a proper meal )

it's not like staying in shape is hard. I lost a good bit of weight last summer in a month and a bit just hitting the gym for a couple of hours a day. Now that's a bit excessive but to lose weight it done the trick, to keep in shape all you need to do is not eat crap and exercise (which walking would constitute) whenever possible. it's not like it's some huge struggle and believe me I have the worst self-control around.
