Childhood Obesity continues...

I think the last line of this article says most of it: 

They also found that physical activity and physical fitness have declined significantly.

Children need physical education at school since they are not getting much at home.  Kids need a properly fueled and fit body to do well in school.  And yet they take phys ed down to a bare minimum and then wonder why test scores decline.

Do your kids a favor.  If the weather permits, go out to the park, or just out in the yard and play with them.  It will make them happier and healthier and possibly smarter.
