I'm not saying you need to not have kids and certainly not suggesting the government mandate a limit. I have a daughter, she'll probably be my only. that's OK, kids are and should be apersonal choice. But regarding environmental impact, not having kids is probably the biggest impact choice that you can make.
I don't quite understand what that has to do with your unrelated nostalgia and bragging. Climbing is fun though, I always enjoyed the rope and pegboard in gym class. And I'm glad highschool was good to you, alotta folks hada pretty hard time with highschool, but I also had a good time, still do! keep the good times rollin'! (by ensuring we don't destroy the planet for future genetations...)
