I started thinking after reading a great book by a great man. As how most of us are being influenced, by a great book by a great man. While reading the book two questions started to appear. The first question was, how cows grow in size and produce milk by just eating grass? and the second question was, how primates by just eating food natural to them always maintain a complete set of teeth? And they don't have to brush their teeth.
So what are doing? Are we doing the right thing? That two initial questions opens more questions and starts a chain reaction of never ending confusion. There might be some answer to this confusion, but where to find them. So I started reading more and more questions appear.
