When I was a kid, I lived baseball and read every biography I could get my hands on. I grew up reading about many players who played and often died before I was even born. I'm pretty partial to the older players because they put up numbers that haven't been repeated without the asistance of performance enhancing drugs, the juiced ball, and change in pitching mound height.
