I could work longer,and harder when I was in the Supermarket business on one hour of sleep. The work was continuous work where I didn't pace myself. If I paced myself I would get sleepy.

I didn't mean to get one hour of sleep before work. It was that I couldn't sleep. I was bothered,and it takes a toll on you. At the job before that,I sometimes went to work with no sleep at all.

I told a fellow worker about that,and he said he wonders why. I believe that he was saying he noticed the same thing in his work,with little sleep. I could do this two days maximum. Then I start sleeping when I get home,and on my days off.
