It depends. My father has been a vegetarian for most of his adult life (so 40+ years). To him meat is disgusting. It's dead animals. He tried an Impossible Burger but just doesn't like it.

Similarly, there are people who have been vegetarian their entire life because that's their culture. India and Italy are home to the largest vegetarian populations.

These people don't wish they could eat meat any more than you wish you could eat grass.
