By the way, I have done a fair amount of mechanic work in my life. While going to college, I dug post holes in silt-clay soil for 8 hours a number of weekends. Try that sometime. After that the same day, we castrated over 30 pigs, docked sheep, drenched sheep and dewormed them. This was after putting in a full 8 hour day. So I have done the hard work.
