When I was growing up, I had a book about the history of baseball that I loved. It went back to Abner Doubleday (it actually cast doubt on the claim he invented the game of baseball) and the dead ball era and I read about people like Mordecai "Three Finger" Brown, Cap Anson, Denton True "Cy" Young, Tris Speaker, Shoeless Joe, etc.. It went into the great Yankee era of the 20s and 30s and further on. I read about Babe Herman and the Daffy Dodgers, Dizzy Dean, etc. and the book continued well into the 1960s.
I learned to become very good at arithmetic at an extremely early age because I would calculate ERA and BA.....my math skills came in very handy at a later age when I got into statistical analysis and electronic engineering. So, I guess I owe a lot to my interest in baseball.
