i think children should have health classes at school

I agree. I thought they do teach health in school. I think it's very important.

I think they should, too. Of all the "possessions" you'll have in this lifetime, I'd think the body is the most important. And we don't even teach the young folks how to take care of it. I've been a physician for 12 years now, and the level of ignorance is just amazing! Recently (last couple years) I've had a weight loss clinic and I'm just astounded at the level of knowledge people have (or rather, don't have). I hear "what is a protein food?" way more often than you'd believe. Unlike cars, we don't have that little tag near the gas tank opening telling us what kind of fuel to use. I'd support the parents providing information, too, but not too many would be able to.
