Fitness wise I see too many fat kids
Me too but I don't hit them over the head with a newspaper and go "Oi! You're fat!". in the long run this will hit them in all kinds of mental and health issues.
Everybody who is overweight has (or will have) mental and/or health issues? What rot! Do you want to just let them be?
Yes. Their life is their business - not mine or yours. No one is perfect, but you can always work towards becoming better.
You seriously need to stop digging that hole of yours. Being skinny does not make you a better person.
