I really enjoyed the book for its science part. I am currently taking a genetics class and there were some beautiful applications inside. The author seems to be a sensible scientist who explains scientific methods well at many points. My plan is to go back to this book and re-read it at some point.
The whole idea of medicine 3.0 sounds great. But at the same time, it does not seem feasible just yet and might inspire some people to do stuff that is not actually scientifically proven or valuable to your overall health. 
The entire field is definitely interesting tho! I remember I had some more specific thoughts, but I did not take notes and procrastinated writing this review for too long. Let me try to re-read it in a few months and then get back to everyone :)

The big takeaways as always: move, sleep, eat, care for your mental health. It will make your life more worth living and even likely longer.
