Seven years ago, I read a book "The Nature of Personal Reality".   I defined this book as Psychology, and some colleges also incorporated it into educational curricula.

The content of the book mentions that cells are renewed each 7 years, so I spent 7 years studying.  If you read it from a psychological point of view, it was actually seeing own-self.

The author is an American, but some Americans said: She was a wizard. 

A few days ago, a The Mixxer partner joked "whether I was a Chinese horoscope." he said.  That's Cool !   It seems that I read the essence of the author. Ha ha...Recommended this Book. Magic!
