Yes, I think kids are being raised as whimps today. I'm not against giving every 5-6 year old a chance to have fun at a ball game. But when I was a kid we could ride out bike downtown at age 12 or even younger. I got to play with matches (I also got in trouble for playing with matches and therefore I learned a couple of valuable lessons. 1, there is a right time and place to play with matches, and 2, I need to be more careful about not letting my parents find out about my playing with matches in the wrong time and place!)
We rode bikes and "jumped" them on ramps and every little piece of raised sidewalk we could find.
I'll be teaching my girls how to perform donuts in a car, because even though it sounds dangerous, it might save their lives, or someone's life in the other car (Knowing how to counter steer probably kept me from running into the car of teenaged girls who were spinning out of control on the freeway in a snowstorm. I was pulling a 25' camper)
I absolutely believe that allowing kids to experience more life at a younger age gives them a chance to understand more as they get older.
