I tried to be vegan, and my shit started to smell lovely, then I went back to a nice chicken stew with curry one day to see the difference and I woke up with stinking mouth and stinking shit.
Life is a challenge for us all. We must all make our choices. A cheetah must eat meat, a gazelle must eat vegetation and a wild bore can eat both.
Who are we to judge anyone of them? It is nature. We ourselves must try and feel and do what feels natural for us.
PS. Oh yes, by the way, I often eat in Happy cow restaurants. It makes me happy inside. 🙂
