A lot of the problems in kids now days reflect directly back on the parenting IMO. Life style habits are developed at a very early age. Granted they can be changed but it's a lot harder when people become accustomed to a certain life style. People now days allow their children to eat crap food, sit inside all day and play video games, buy them cell phones, let them sit on facebook for hours. If you live an active life style, eat right and teach your children to do the same they are more likely going to continue to do so as they grow older. It's a lot of the parents that let their kids walk all over them and would rather just give in to them because it's easier than having to battle with them, thats the real problem. Kids need guidance and need to hear the word NO. I think that is ultimately the reason why we see such an increase in health problems across America. Kids aren't driving themselves to fast food joints and buying all these video games. It's all one big chain reaction.
