JGN, Needless to read such books, now being an Indian you could not inculcate the greatness of the culture and Heritage of India, and your answer gives me a feeling that you are a Book worm who does not have any worldly knowledge and lives in dreams or idiotic thoughts. Coming to the Civilization, gentleman (Ha Ha)A civilized man would try to understand ones own culture, ones own civilization and promotes Heritage, you are the Biggest CRAB who is not fit to live in India. Coming to the life span of Human beings, better check in Himalayas you will find the people who are living for centuries go and check for yourself.
