吃饱了就困，睡醒来又饿。
其实是医学的常识。吃饱之后，胃部血液循环旺盛，而脑袋中的血液循环衰弱，引起大脑缺氧，使人感觉昏昏沉沉；而睡醒之后，腹中食物消化殆尽，自然又饥又饿，难以忍受。
所以，懒惰是人的正常生理状态，不是人的病理状态。
本书未探讨堕落背后的生理基础，而是从数学角度出发，用公式和定理来计算堕落的相关问题。
译者前言
关于本书的来源，乃是baby myself在某日白天的睡梦中梦到的。尽管我睡了将近13小时，但我只能大概还原原书的序和主要内容，只有不时穿插于章节中的erotic成分使我excited such that I can hardly forget ever。原序大致如下:
“Going down may oftentime be regard as a topic of personal issue on books of success(nowadays here and there), sometimes discussed in social science, even seen in a philosophical book. It is a wide range issue such that people can easily neglect the mathematical principles which it based on.
Oftentime economists take the laziness of labor into consideration when it involves the analysis of productivity and the execution of social responsibilities. They reveal the the humanity occasionally with blurry words which they feel shamed even to mention it, while I have to show my sympathy for their view of it as something bad, or property of individuals. Hence hardly ever have we heard the research about this unspeakable laziness issue in other field. Is this the collective laziness of the all academics?
This book will not discuss how we blame and cure the the laziness of people, but the measures and the mathematical principles it based on.

由于本人在回忆的过程中不时地陷入昏睡，加之记忆力日渐衰退，原书内涵不能尽表之处，实乃遗憾。

力学符号F=force, 原动力motivation or here is "original force"
功P=power, 能量E=energy
懒惰L=laziness
系数co-effitient
第一章 懒惰是科学发展的原动力
F=aL, a为懒惰系数(可以为数值或矩阵)，F为懒惰力，根据牛顿相互作用力，F=-F，我们can explain this as "懒惰力越强，对社会的推动力越大"
