Eminitrader: To crack open the fourth ventrical of your brain was done back in 1979 in europe, for dr chang in west bengal it was a routine practice since late 80' and throughout 90 and I am sure he still performs such procedures. BS 2054 in daily kantipur new year special issue upendra claimed he was the first person to risk with that kind of surgery. He added that after spending hundreds of hours with american surgeons he claimed" this is first time even in the field of neuro-surgery!!!!". And to your question what I do for living? that not something you want to know I assume,but since you asked here it is: I work for a medical research institute, and yes I do know the difference between an expert and pioneer.
