Take away their cell phones and video games then teach them to ride a bike.

Another thing: Unfortunately, with all the school consolidations going on, few children walk to school anymore. Instead, they ride many miles on buses. I remember walking at least a mile to middle school and high school (yes, I know, uphill both ways), then the school board decided we should ride the bus - even though no child ever had gotten hurt walking to school.
