Eating non veg food.

I am vegetarian and I suggest others too

You can try....just make sure you cook it well. Personally I don't like red meat...I get what I need from chicken and eggs.

The Japanese eats meat regularly and they have the longest lifespans in the world.

I think this is a personal choice and whatever is the decision, just in moderation

In moderation everything is alright.

Of course not.If one studies the anatomy of human body,they will get to know that our intestine patterns are meant to consume veg foods only.Cannibals on the other hand have a different intestine set up that facilitates non veg food consumption.I personally prefer veg food because i don't like innocent butchery of animals just for the sake of satisfying our taste buds for few moments.
