80 hours - I worked my normal 7PM-3:30AM snow plow, one-man shift, in a storm, staying on until the day shift arrived, went home and found that my wife was violently sick, she was the elementary school bus driver and custodian, did what I could for her and since I was the back-up school bus driver I went and picked up kids, came back and took care of my wife, drove the bus after school, cleaned the school, and went back to work the night shift plowing all night in the continuing snow storm. I did that for 3 days until my wife got better. I was pretty whipped by the end.
