Around 2006 I read a book called Eating Animals. Then, as time went on, I watched many documentaries including Cowspiracy, Earthlings, What the Health, Peaceable Kingdom, to name a few. Watched videos depicting sweet animals going through such terrible pain, misery and suffering until finally a certain video broke my heart and i said NEVER again will I ever eat another animal and I never have since. That was 2016, went fully Vegan Feb 2017. My partner went right along with me.
