  As living beings, humans require a baseline of good health, nutrition, rest, and other physical needs in order to reliably exert themselves. This is particularly true of physical labor that places direct demands on the body, but even largely mental work can cause stress from problems like long hours, excessive demands, or a hostile workplace.
  
  Particularly intense forms of manual labor often lead workers to develop physical strength necessary for their job. However, this activity does not necessarily improve a worker's overall physical fitness like exercise, due to problems like overwork or a small set of repetitive motions. In these physical jobs, maintaining good posture or movements with proper technique is also a crucial skill for avoiding injury. Ironically, white-collar workers who are sedentary throughout the workday may also suffer from long-term health problems due to a lack of physical activity.
