I read this while I was preparing for one of the final exams of my biology degree, so perhaps it’s no surprise that I found it helpful in revising some of the topics (mostly apoptosis!), but also found that knowledge useful in understanding the book itself. To me, it seemed an incredibly clear and well-written account of the role of mitochondria in life and the origin of life, and I didn’t really find any major holes in it based on what I know. If you’ve read The Vital Question, then a lot of the ideas in it aren’t new — but of course, that makes sense, since The Vital Question is a more recent book by the same author.
And since this is pop science, I should add that you don’t need the biology degree to understand it. It might be slower going and less like pleasure reading if you don’t have a solid background in science, but it should work at that level too.
I do roll my eyes a little bit at the title, which is obviously drumming up excitement by sounding provocative and then like a self-help book, but hey, maybe it’s persuaded someone on the fence to pick it up just through sounding a bit unusual for the section it’s in. It’s worth picking up, definitely.
