When i went vegan, there was not so much information available for me. I had a computer and internet connection then, but i wasn't even aware of who vegans were. But i had some nasty conditions by that time, like ridiculously high blood pressure, ulcer, excessive weight, swelling, varicose veins, haemorrhoids and never ending constipation.
I was raised in a family which had a diet extremely heavy on meat. When i met my future ex-husband, my diet got a lot worse: endless bbq, meat cutlets, sausages, cheese, fish... It was to be expected, that my health issues got worse.
I couldn't take it anymore, especially high blood pressure. My granny Nina had severe atherosclerosis (she was alive then), but i couldn't make a connection, because i knew nothing those days. All relatives from mom's line (Beloshapko and Koziks) had illnesses which we would now characterize as "diet-related" or "related to meat consumption"... but i couldn't make a connection either.
I was scared, because i was feeling that something wrong was happening to me, but i didn't know how to fix it. Well, Sumerian gods told me (very briefly, and they said i would have to educate myself in the future). By that time i'd heard something about vegetarians, but i never heard of vegans. I only knew that i should ditch animal-derived products. I decided that vegetarians are those who don't consume any animal-derived products, because i assumed (based on the root of the word), that "vegeta-" means that you eat only those things that grow (in soil)... but animals and their flesh don't grow in soil (those were the thoughts in my cabbage head, lol). I started digging info in the internet. There was almost no info about veganism in Russian language, so i started reading and watching sources in English.
In a very short time, i felt significantly better. I didn't think of environmental reasons then, or of animals who suffer and who are being killed violently. But as i gradually proceeded with self-education,- i realized that total consumerism i was raised in, is very wrong and produces only death to all... to the planet, to the animals, to humans and to human spirit.
There were no humans around to tell me that i should change. Shumerian gods overcame any obstacles possible to tell me the truth, so that my pathetic human mind could percept it and understand it. They literally saved me having told the naked truth, and they continued to support me later, telling me what i should eat and drink, and what i shouldn't. They made me get addicted to kapusta, and beans, and grains. Now that i have plenty of information around, they continue to stay my most reliable and trustworthy source: i ask them first, then check it out in the internet, and then take steps, according to what they have advised in the first place.
I believe that any reason is good (to go vegan), but to stay vegan, one needs to comprehend all reasons.
