Now, I'm no shrinking violet. I played hockey until half of my teeth were knocked down my throat. And I'm extremely competitive on a tennis court — I'll dive for any ball on any surface. But that experience at the slaughterhouse overwhelmed me. When I walked out of there, I knew I would never again harm an animal! I knew all the physiological, economic, and ecological arguments supporting vegetarianism, but it was that firsthand experience of man's cruelty to animals that laid the real groundwork for my commitment to vegetarianism.
