	This table organizes occupations into two main categories based on their activity level. Roles identified as having low occupational activity include those in professional, managerial, administrative, and clerical fields. Examples of such positions are executives, managers, engineers, secretaries, and technicians, typically involving less physical activity. In contrast, occupations classified under high occupational activity are largely made up of manual labor and skilled trades. This group includes construction workers, machine operators, and agricultural workers. Furthermore, occupations in the service industry, such as waiters and cooks, along with those in protective services, are also part of this high-activity category, demanding significant physical effort and continuous vigilance.
