Primordia Medicine: The Most Comprehensive Preventive Medicine of the 21st Century is a book mainly about preventive medicine and conveys some basic knowledge and deeper concepts of health. The author owns Ph.D. for both Medicine and Biochemistry in Cornell Medical College of Rockefeller University and he did lots of research on the relating fields as well.
The most important idea I've learned from this book is that how to get along with Mother Nature peacefully and harmoniously. By always feeling grateful for everything around me; making sure to introspect what I've done improperly or wrong every day, and learning from the mistakes; trying to hold a thread of hope because once there's hope, nothing is impossible, and lastly, remember to repay the nature and society since I've used their resources all the time so it's reasonable to give anything in return. :-)
