On a beautiful summer day, when I was six or seven, my grandfather took me swimming. This gave me the opportunity to examine every feature of his body. Previously I had already noticed that, unlike any other human being I had laid eyes on, grandpa distinguished himself by growing extremely bushy and wavy eyebrows. Not long before this swim outing I had heard somewhere that human beings had evolved from ape-like creates. Now I discovered my grandpa

Great many facts presented themselves in the years gone by, telling me very strongly that my great-great grandfather was not an ape and human beings have been as intelligent we are today for thousands years. But my brain continues to fool me into thinking we are very different today from human beings who lived only a hundred years ago. Didn
