I wasn't particularly sporty but as kids/teens, we were always outside playing/building forts/going for bike rides, etc. My own teen kids are very into their computers and I do struggle to get them outside in the fresh air. It does bother me that they don't get enough exercise - we even bought a tramploline which gets used sometimes in the summer, but they are getting to an age now where I can't 'force' them to go outside, etc. I just hope that as they get older they'll want to do more with their spouses and own kids, rather than just sit hooked up to a machine. Well, I can hope.
