I don't know anything about the brain, but it is clear that we can survive quite happily without certains organs. I have just recently had my gall bladder removed, "You can live quite happily without that", said the surgeon. 40 years ago, as the result of an accident I had my spleen removed, "You can live quite happily without that",said the surgeon. I sometimes get the feeling that I am going to the Promised Land in bits and pieces. I only hope that when the time comes the undertaker will give a discount on the missing bits.
