Birbhadra asks: "Ashu, how do you know everything?" Answer: I don't. I never did. I never will. That is why, I have always said that ALL my publicly-expressed ideas/thoughts about anything are always OPEN to criticisms, objections, modifications, challenges and improvements. In an OPEN forum, If I am wrong, I'll get corrected quickly with better facts and stronger arguments. If I am right, maybe I'll make a few people think differently about an issue. Either outcome is fine with me. After all, the relentless process of self-learning -- through reading, writing, observations and many stimulating conversations with friends -- goes on and on, on and off Sajha. oohi ashu
