What is the physical work and mental work?

Physical work refers to any activity that involves the use of the body to perform tasks, such as lifting, moving, or manual labor. It often requires energy expenditure and can lead to fatigue in the muscles. Mental work, on the other hand, involves cognitive processes such as thinking, problem-solving, and decision-making, which can lead to mental fatigue. Both types of work are essential for productivity and well-being in various contexts.
