This is a small book (around 200 pages) but can have a big / profound impact on the way one sees others and themselves. Will make you introspect and grow to become a better human being. Good book for your personal collection. Must read atleast once a year.
Eat less, smile more, have good friends, stay active & keep moving. This book is based on facts from real people from Japan who lived till 100+ years. Good read.
