A few random thoughts:
It's a problem. (duh)
I feel like kids today don't even have a chance growing up around the kind of food that's available... like, a 5 year old kid doesn't know anything about food and since fastfood restaurants are EVERYWHERE, that's what he'll be eating. By the time he's older and realizes that it's bad he'll already be 50 pounds overweight... today's children are basically doomed unless they have very health-conscious parents or good genetics.
Also, it's just plain alarming to see how many people are overweight or obese. I'm not talking about an extra ten pounds, I'm talking huge. I work sometimes in a hospital, and it really scares me how many healthcare professionals are extremely overweight. If they, of all people, (being so educated on HEALTH) don't know better... yikes.
