The Lives of a Cell by Lewis Thomas (1974, ISBN 978-0-14-004743-1)
Subtitle-- Notes of a Biology Watcher.
This book contains a series of essays originally published by the New England Journal of Medicine. I enjoyed these essays, found interesting. A few time I found stuff that was out of date, nut that should be no surprise, since they were written more than 40 years ago. Was an xmas gift, xmas 2015.

Sapiens by Yuval Noah Harari (2015, ISBN 978-0-06-231609-7)
Subtitled-- A Brief History Of Humankind.
Very interesting book, one of those books that I feel like I want to re-read as soon as I have finished it. Discusses the long history of humans, from the first humans 2 million years ago up to present time.
Divides human history into three basic eras: Cognitive Revolution, Agricultural Revolution and Scientific Revolution.
