My grandfather, Thomas Purinton, enlisted in the Navy at age 16 in 1899 and was assigned to the square-rigger USS Essex, and my Massachusetts ancestors fought in the Revolutionary War, so I was favorably disposed to military service. When I was a second-year medical student in 1971, one of my colleagues was accepted into the Medical Osteopathic Scholarship Program, which is the Department of Defense program to recruit future physicians.
