Vegan for one year, vegetarian for almost 6 years. I read many books about the topics [one of my favorites being "How Not To Die"], listened to podcasts [my favorites being "Dr. Greger's Nutrition Facts" and "Brown Vegan"], as well as watched many documentaries [my favorites being "Cowspiracy" and "What the Health?". Going vegan has already been a huge improvement for me in my health and happiness, and has opened so many doors to eating to live and not living to eat. I don't think I could live any other way now.
