‘One log, nine holes’ is an ancient riddle I read once somewhere and not in a golfing book. Two O’s of the eyes take in half of our world at a time. The O’s of hearing, in one ear and in the other. O of the mouth, like Jonathan Jo in A.A. Milne, shaping every watery sound: Artichoke, Electricity, October. The O yes or O no of scents in the nostrils as they regulate breathing. O of the anus, O indeed, but healthful and harmless. And O of the genitals, without which life as we know it would not exist.
