92-year-old yogi, B.K.S. Iyengar, is in a new PETA ad, "Energize Your Mind, Body, and Spirit. Go Vegetarian." Iyengar credits his vegetarian diet with living a long and healthy life.He tells PETA: If animals died to fill my plate, my head and my heart would become heavy with sadness. Becoming a vegetarian is the way to live in harmony with animals and the planet. Do you prefer Iyengar's ad over Pam Anderson's latest PETA ad?
