This is a great book on dealing with a subject matter that we try to avoid at all cost and that is death and immortality. It expands into our fears of death and what we go through to avoid it. He says our bodies are hard wired to reject mortality. We create immortality narratives to deal with the fact that dying is what we want to avoid. Including wanting to live forever and be immortal.The author suggests that we ought focus on living a great life in the present one of gratitude and creating a personal legacy. I would add that race for immortality is also creating a parallel benefit which is life extension with great quality. I highly recommend this book. I deal with a very difficult subject matter in a very uplifting and positive manner. I also wonder what Immortality is in terms of years for most of us, for me it is 150 to 200 years. A great motivator to live longest and with superb quality of life.
