Remember the Wii? Yeah, Get Back On It.

Many children in the world are overweight. Many children in the world also play non-active video games, or, as I like to call them, normal video games. But studies have shown that overweight children that have played "active" video games have gained less weight over time. And experts say that if more children played more active video games, child obesity would go down.
But you know what? It isn't just video games at fault. The parents of the obese children are probably not doing anything, or maybe even helping the child to be obese. Maybe if the parents stopped buying chips and junk for their child, buy some dang apples, they're probably cheaper anyway. And if the parents are obese, they should buy some apples for themselves too.
