I did go vegetarian (been vegetarian for ~15 yrs now).

Back during the birdflu scare (2008-09), my parents decided to stop eating meat (chicken - which was the only meat I used to eat). I was ~12-13 yrs old.

Overtime, I wanted to switch back but for some reason or another (saw some videos on Youtube about how chickens are treated and killed didn't sit right with me), never did.

We cut meat immediately. While I didn't miss a lot it, I did eat a lot of soy in the interim period (ofc a few friends of mine who tried didn't succeed).

Just as an FYI: Don't watch those videos if you like stuff like leather for example...I love the feeling of leather seats, but I'm looking for synthetic leather in my next car.
