I have been considering becoming a vegetarian.  Have you ever thought of it?
1_Wizard
Yes, I actually go through period in my life when I eat vegetarian. The idea of this way of eating comes from ancient India and Greece. And i love Indian food!

Really?  When did it come about?
1_Wizard
Hm.. it would have been a very long time ago, because in the 4th and 5th century after Christianity became permanent in the Roman Empire it dissipated for a while.

That is very interesting.  What were the main reasons for having a vegetarian diet back then?
1_Wizard
Well in India the voluntary non-consumption of animal flesh was partly a religious thing. Many Hindus are vegetarian. Have you tried Indian food? It's very delicious.

I have and I do enjoy it.  Did they discover the positive health benefit of a vegetarian diet or was it purely religious based?
