Increasing numbers of senior citizens remaining in the workforce have raised concerns among experts and safe driving advocates. Researchers at the Pew Research Institute say that 18.5% of the 65 and over population will continue to hold jobs. Additionally, researchers at the Centers for Disease Control and Prevention have released statistics showing that drivers aged 65 and older are three times more likely to be in a fatal auto accident than drivers aged 18-54. As people in the twenty-first century live, and work, for longer, some experts have suggested that employers should give physicals to employees in certain kinds of jobs that require driving.
