My props to the farmers. I have never been associated with a farm so I could never really understand those aching muscles and sheer physical payload day in and day out. I will argue this, however:

Mental/cerebral strain is just as draining as physical strain.

What is the difference between pulling, planting, bending, lifting, hoisting, throwing and rapid fire decision making, subtle manipulation, calculating, problem recognition and problem solving, and other mentally draining tasks.

Sort of like one of my coworkers. He can fix the car, but I can fix the copier. You would not want me fixing the car and he should just leave the copier alone.

And needing to do fifty million things in one day while only having time to do twently million things will put some spring in your step.
