The appeal of "green spaces"

A mere five years ago I still saw children playing in their front yards, even in the streets, and riding their bikes throughout the neighborhood. I don't see that anymore. Every time I go to visit Clients at their houses, the children are in front of their very own plasma television watching their personalized copy of some movie, or listening to music on their very own iPod, or calling Grandma on their very own cell phone, or on their very own computer answering their emails. I hope when virtual reality gets here that there is a virtual fitness program with it.
