Researchers at Harvard Medical School have crunched the numbers in almost 9 million U.S. death certificates issued between 2020 and 2022, looking for links between occupations and Alzheimer’s as a cause of death. It seems there may be a benefit to being on the road.

Of nearly 9 million million people with certificates listing occupation in the U.S. National Vital Statistics System, 3.88 per cent had Alzheimer’s disease listed as a cause of death, amounting to some 348,328 people.
