When my fiance explains the different reason why to be vegan; what I have noticed the most convincing fact is the reverse aging stuff. People want to feel younger. When my fiance asks them, how old do you think I am? They say 35, 38 no more than that. They become astonished when the answer is 53. In our society, asking a woman to reveal her true age is like a tabu. We don't mind, that's when they pay attention to it.
