No vegan has lived on a pure vegan diet long enough to not have severe issues. If you search you will find tons of former vegans who were forced off of their pure vegan diets by severe medical issues. People who call themselves βvegansβ and are still doing well after a long time are either really vegetarians who eat a lot of animal-derived products to compensate, or cheat and eat meat here and there.
