While the work attracted continued support from advocates of psychosomatic medicine, many in experimental physiology concluded that his concepts were too vague and unmeasurable. During the 1950s, Selye turned away from the laboratory to promote his concept through popular books and lecture tours. He wrote for both non-academic physicians and, in an international bestseller entitled "The Stress of Life" (1956). From the late 1960s, academic psychologists started to adopt Selye's concept of stress, and he followed "The Stress of Life" with two other books for the general public, "From Dream to Discovery: On Being a Scientist" (1964) and "Stress without Distress" (1974).
