"Age at the wheel spells safety. An investigation among omnibus drivers has shown that the general tendency is for the accident rate to decrease with age, This same tendency had been found in the case of industrial accidents. Graphs showing the relation between accidents and age reproduced in "A Study of Accident Proneness Among Motor-Drivers," by E. Farmer and E. G. Chambers (Industrial Health Research Board of the Medical Research Council), published by the Stationery Office. In all the curves of the graphs there is a slight rise in the accident-rate about the period of middle age, followed by a fall, "A possible explanation of this," state the authors, "is that advancing age may come almost imperceptibly upon people, so that they continue to take the same risks as they did in their earlier years. When they are definitely old they realize that this cannot be done, and so take fewer risks. Whatever the cause, the tendency is fairly well marked in all the graphs dealing with the relation between age and accidents in groups with a wide age-range."
