Anthropologist Germaine Tillion, a member of the French Resistance and deported to a concentration camp, was still working on the eve of her death. Back from that horror, she decided to laugh until the last minute, awakening around her a group of friendship, mutual help and joy that lasted until she was 101 years old. For many, the onset of old age means that everything is lost: memory, freshness, brain..., but this book shows, on the contrary, that resilience is also possible in the elderly. The psychologists, neurologists, psychiatrists, geriatricians, and even a veterinarian that this book brings together help us to understand how involved in this vital process are the bonds of attachment, interactions or memory, but also emotions, motivation, humor and music. A book with valuable lessons we should incorporate to our life's luggage.
