I'm not a big fan of video games...but its not always video games that keeps kids off the streets.
Kids are a lot busier now-a-days too.....when I was a kid, My Dad worked, My mom worked Part Time, and I went out and hung w/ friends, the end....got into some trouble as well too
Things are Uber-Organized now-a-days...friekin playdates....WTF....gotta schedule getting together now.
Now my kids growing up had Soccer, Baseball, Softball, Basketball, Scouts, Dance...right now my son does Drama, A-Capella, and Jazz Ensemble as well as Boy Scouts and Ventures during the week....my daughter does Dance 3-4 times a week after school, and is a Homework Junkie (2-3 hours a day).
also when I grew up I lived in a city...walk out my door and had 15 kids my age within 200 yards of my house...easy to find kids to hang with. where I live now....the nearest boy my son's age lives 3/4 mile away.....don't have that closeness.
I think the Obesity thing has a lot to do w/ the crap kids eat as well as lethargy on both their's and their parents part. There are a good number that really are just wasting away in front of the video games....and parents need to kick them into play....takes work to do and people are getting lazy as a whole
