Draft dodgers were very common around the time of the Vietnam war. This group of men would injure themselves, fake their age, or force themselves into higher education in order to avoid being drafted into the American military. At the age of 18, if you were an American male who was of good health and low education, you were required to register as a member of the American military draft.
"Then, in November 1969, after I'd been in college for a year, the rules changed. A lottery began phasing out student deferments. My roommates and I started thinking and talking more about the draft. It occurred to me that the people on the draft board were human beings who deserved a friendly hello as much as anyone did, so I wrote them a letter." - Eric Schechter
During the Vietnam War, about two-third of American troops were volunteered, the rest were selected for military service through the drafts. In the beginning of the war, names of all American men in draft-age were collected by the Selective Service System. When someone’s name was called, he had to report to his local draft board, which was made up of various community members, so that they could begin to evaluate his draft status. By this manner, local draft boards had an enormous power to decide who had to go and who would stay. Consequently, draft board members were often under pressure from their family, relatives and friends to exempt potential draftees.
