Oops, when I made my post, I said to myself 'not one left', and answered myself (I am a great self-conversationalist you see), 'nah, that crowd could never have left one alive'. Just goes to show you, try to avoid absolutes in statistics. Those Zoroastrians in Iran must be one tough bunch, to have held on this last nearly 1400 years of savage persecution, I wouldn't want to mess with them. Their burial practices still are unlikely to win them many 'good neighbor' awards, I'll wager.
Persians and Turks are not completely like Arabs, I think because they are still influenced by their Zoroaster religion & culture and didn't succumb completely to Islam.
