Power, sex, suicide
The final chapter of the book looks at the part mitochondria play in ageing, and how we might be able to slow it down. I feel that it is important that as many people as possible find out about these possibilities in order to have an imformed debate about the ethical issues.
Although this work is aimed at non-specialists, I think that readers without some background knowledge of cellular biology are likely to struggle. The book looks at recent research, often requiring subtle arguments on why we think differently now from 20 or 30 years ago. However, if you do have the required background knowledge then reading this book will be very rewarding.
