The "eating Advil" comment makes me quesy. I pitched my senior year of high school with a sore back. I just didn't know it until several hours after the game, when the eight Bufferin I took before the game wore off. I had no idea what the potential health hazzards were of doing this twelve times in a season.
The expert advice I received came from a Legion teammate with a nasty slider at age fifteen, who pitched three years of high school ball on Bufferin. His arm died soph year of college.
