Well, there is nothing wrong with becoming a vegetarian as long as you really know what you are doing. Humans are omnivores so we are supposed to eat meat but being a vegetarian is possible if you read up on how to get your proteins and what a good diet is, vegetarian style.
Another thing with being a vegetarian, be prepared to be more GASSY. It just goes with the terretory.
I don't think there are lessons to be learned as a vegetarian except you have to remember how to eat well.
Being a vegetarian typically costs more. You will more than likely make more trips to the store.
I shop once a week (maybe). Being a vegetarian would not work for me. It's stuff like that you have to think of.
Then there are a few forms of being a vegetairan. You could go all out and go no milk, cheese, eggs, ice cream.
Or there are vegetairans who just don't eat actual animals.
Personally, I don't see the point.
Vegetarians have reasons to be vegetarians. What would be your reason?
