Oliver Sacks wrote a succession of popular books about strange medical conditions, most famously The Man Who Mistook His Wife for a Hat, and a well-received autobiography, On the Move. He died at the end of last year. This short book – beautifully produced in a gift format – includes four short essays written in his old age and in expectation of his imminent death. The title reflects how he felt about the gifts that life had given him. The final essay - his final essay, is a meditation on the Jewish Sabbath, the Shabbes of his youth, where, after describing the Orthodox practice of friends and their acceptance of him as a gay (married-out!) atheist, he comes round to seeing his own life as a Sabbath, with the feeling that he has done his work and can now, at ease, rest.
