Obesity is such a hard thing for to feel bad for someone to have because it's a very "first world" problem.
I mean this in that, yeah if someone has cancer, then yeah feel bad for them they don't deserve it etc etc.
However if someone's just sort of wasted their lives away and not taken care of themselves enough to get obese then I can't help but think it's their own fault pretty much, and if they cared enough they could do something about it.
You don't see advertisement for african kids weighing 15 stone do you? So I can't help but think it's natural selection.
Of course It's easy for me to say this when I'm only 11 stone and 6'2. So I've never had any problems with getting fat, I don't know if it's easy or if it's something that just creeps up on you.
