«In nature, there’s no old age or decrepitude. There is just plenitude and death.»

«We would love to find out that every species has a biological clock in its cells, because if this clock existed and we were able to find it, maybe we could stop it and become eternal,» Arsuaga tells Millás in this book that mixes science and literature. The paleontologist reveals essential aspects of our existence to the writer, and he wonders whether or not it makes sense to transmit his haphazard vision of life to a Millás who is on a diet and discovering that old age is a country where he still feels like a foreigner.

After the extraordinary success of Life Told by a Homo Sapiens to a Neanderthal, the most brilliant tandem in Spanish literature is back to charm readers with discussions of such subjects as life and death, eternity, longevity, illness, aging, natural selection, cell death, and survival.

Humor, biology, nature, and lots and lots of life, with two fascinating characters, the homo sapiens and the neanderthal, who surprise us on every page with their wise reflections about what evolution has done to us as individuals and as a species.»
