Wonder of genes: Why do we feel blood type [and personality] is true? by Satoshi Komiri

Here comes a kindle book (in Japanese) by Toshi Komori who retired from Toshiba and entered the graduate school of Tokyo University.
The book is not full of formula nor difficult, but a science reading which can be read with ease.

However, this title can cause some misunderstanding.
The "correct" one is "blood type [and personality] is true". Wow!
