Because manual workers and knowledge workers get mentally weary in the same way and make mistakes in the same way, using their brains. Your muscles are perfectly capable of going longer. Your attention span, working intelligence and executive function are going to get messed up whether you’re putting 60 hours into putting the right amount of powder into every container or checking the Excel formulas are all correct.
Manual laborers are people no less than accountants or mathematicians.

For example, I can easily work twelve hours per day while painting the facades of my home, without being mentally fatigued, only bored. But my body is surely sore after climbing up and down stairs all day. On the other hand, I’m hardly capable of doing six hours of really focused mental work per day.
