There is so much more technology nowadays, meaning that there is more for teens to do indoors. Also, the fear of abduction means that parents are less likely to leave children outside without supervision. I totally see how this could create major health problems within society.
Yes I can see this happening just as I see the movie Idiocracy coming more and more true as time goes on. I think that the two go hand in hand as society is going down a path we should not be. Letting your teens have all the technology available for them to use all the time is not helping at all.
