There are two main explanations for lazy people's excrement and urine in life. One is that lazy people don't move much, and the added water will not be discharged with sweat glands, so they urinate a lot and often have nothing to do. The brain is relatively sensitive to rectal signals, so there is more excrement; The second is to describe lazy people as really lazy. When it comes to things, they use shit and pee as an excuse to avoid work.

There is some truth in the saying that lazy people have more shit. Moreover, the appearance of these statements is not a scientific summary of events, but an observation of some social phenomena, which correspond to certain social reality or productivity. When the social conditions that produce it exist, it will appear, and when the social conditions change, it may not adapt.

Lazy people shit a lot, which is a summary of some phenomena in traditional society: in traditional society, many jobs are done by people, and in the past, a small tractor could not finish it in a few days. People living in the era of industrialization and information technology can hardly imagine the labor intensity that people paid to survive in the previous social form.
