I had been a vegetarian for the last 2 and a half years, prompted by viewing the chicken transportation truck that drove daily past my old apartment on its way to some Brooklyn slaughterhouse. Then 2 and a half years later I realized that I had been tired and hungry for the last 2 and a half years. I started eating meat again after my friend directed me to paleonu.com, where everything I read made an overwhelming amount of sense to me.
