Working hours for a normal human!!!

For today's lecture, it was really fun, I enjoyed it so much!

Today, Prof. Heap talked about the technology we created for efficiency and effectiveness in human society.Prof.Heap told us, if a human keeps working up to 21 hours without any rest, this person will feel so tired and he/she cannot focus on the project properly, and some problems will occur. It is very dangerous.

And we also drew a chart of human's productivity under crunch mode:

In this graph, we can see that above the time-axis, the shaded area is the productivity. As we can observe that at the beginning, as time goes by, our output is increasing, and the productivity at the beginning hours is really high. However, after a certain amount of time, the output becomes to decrease, and at a pretty fast speed. Surprisingly, at a certain time, output can even become negative, which means the total output is decreasing, and at an increasing speed. As we have been explained in the lecture, the negative productivity is because as a worker works too long, some unavoidable mistakes will occur, and the worker cannot concentrate on the work very well since he/she is too tired to work properly. Therefore, this is the reason why the crunch mode for human is not possible, it will not increase efficiency, but ruins all the work which has been done. 

So, from this lecture, I learned that, no matter work or study, we cannot just keep doing something without any kinds of rest. Even though we believe that we have the ability to finish all the work within a continuous working process, but our body is always honest. If the body cannot work properly, even if we have our spirit to support us, we still cannot do everything as good as we expect. From learning this kind of information, we conclude that enough rest is necessary for our bodies to recover, and then we can do work by a higher productivity. So no matter how busy I am, I will cherish my body, and I will rest if I need rest. And then I can do a better job!!!
