Oliver Sacks died in August 2015 at his home in Greenwich Village, surrounded by his close friends and family.He was 82. He spent his final days doing what he loved: playing the piano, swimming, enjoying smoked salmon – and writing . . . As Dr Sacks looked back over his long, adventurous life his final thoughts were of gratitude.In a series of remarkable, beautifully written and uplifting meditations, in Gratitude Dr Sacks reflects on and gives thanks for a life well lived, and expresses his thoughts on growing old, facing terminal cancer and reaching the end. I cannot pretend I am without fear. But my predominant feeling is one of gratitude. I have loved and been loved; I have been given much and I have given something in return; I have read and travelled and thought and written.I have had an intercourse with the world, the special intercourse of writers and readers.Above all, I have been a sentient being, a thinking animal, on this beautiful planet, and that in itself has been an enormous privilege and adventure.
