We are really no farther along than we were when this miserable $#@$#@ disease was identified more than 120 years ago.
Candlestick Park was built on toxic waste, refuse from the Navy and other land fill. I am drawing no conclusions. Former Veterans Stadium in Philadelphia had a staggering amount of ex baseball players die of Brain Cancer.
