The best book i have ever read.The info at many times go against your routeen life and common beliefs which actually are true if given a carefull thinking.It infact changes ur opion on how u portray the world and how deceptive history is as u know of.sometimes i involuntarily pause while reading and get carried away into the world of imagination jst to appriciate how intelligent yuval noah harari is in his analysis and information he provides.its not the facts and evidences in the book which makes it special but the analysis and correlation of facts with several timelines and into the modern world.READ IT.
