My parents had us very young. We lived in a modest house. We built forts, we hiked, we went camping and they wanted us to be independent. It's how children grew up in the 1940s and 50s: outside all the time, playing in the dirt, riding your bike around.
Baseball is a team game but, at the same time, it's a very lonely game: unlike in soccer or basketball, where players roam around, in baseball everyone has their little plot of the field to tend. When the action comes to you, the spotlight is on you but no one can help you.
There is nothing more corrupting, nothing more destructive of the noblest and finest feelings of our nature, than the exercise of unlimited power.
