"Occupational requirements" are a major factor in external motives. In stage, film and television, for instance, "where nine women out of ten aren't all real" and where winning features and a good figure are a woman's greatest assets, cosmetic surgery is quite reasonably seen as a sound professional investment.
以「外在動機」來說，「職業需要」是主因，例如在「十個女人九個假」的演藝圈中，姣好的五官和身材既是最大本錢，美容便順理成章地成為一種職業投資。
