I say that good looking people will have even more reason to be arrogant and self obsessed, now that obese people are on the increase and better looking people are becoming more of a rarity.

I also say that despite Jamie Oliver's efforts, lots of schools do tend to serve very nice pizza and chips etc, the garlic bread at my secondary school was particularly nice...
Eating such foods on a daily basis can have many negative effects.

And like you said, lack of exercise.
Technology is to blame im afraid, that and lack of parenting skills. Far too many parents are lazy and don't do anything with their kids, just go to the pub or sit around the house etc, thus setting bad examples for their children in the process.

What really irritates me is obese people who got themselves to such a weight out of pure laziness, greed and being irresponsible...then insist they have surgery because "Once the weight is off they'll make an effort"
Lol, the whole reason they were in that mess in the first place was due to them lacking the will and effort within them, it's slightly pathetic to me.
