20 years ago, I'd agree, and you don't see too many fat old people...but teenagers, and even little kids...I see fat kindergarten kids every day...it's child abuse in my opinion. Some of those fatties are still being pushed in strollers at 5 years... lunchtime and McDonalds is rammed, some kids have McDs for breakfast and lunch.
It's actually inspired me to shed some kilos and practice what I preach so I can now honestly tell kids that I never eat fast food or drink sodas...It's scary...don't see too many kids smoking, so that's something I guess...I tell my students that they will break me if I ever see them smoking, lol! But it's probably true.
