I have been thinking about the same question for a long time. Because I didn't feel this before, but recently, I slowly understand that age is not forgiving, I am already in my thirties, and gradually feel the physical exhaustion, when I really lie down, I feel very comfortable, and gradually I have some of my own feelings, that is, when lying down is more comfortable than sitting, when sitting is more comfortable than standing, what is the reason for this?

I also thought about this question for a long time, and then I also had my thoughts and explanations. According to the physics knowledge I have learned, I know that the weight of a person is certain, that is, the mass of a person is certain, weight and mass are the same thing in physics, and the force area of people is not the same, when standing is the force of the two feet, the force area is the sum of the area of the two feet, and when sitting, it is the buttocks and feet are under force, so the force area is much larger, so sitting is more comfortable than standing, the same reason, when you fall asleep, it is the whole back body is under force, so at this time, the force area of the body is larger, so the pressure is small, so you will feel comfortable, what a simple truthAlthough I am not a physics major, although a lot of knowledge is now returned to the teacher, but there is some knowledge, some basic principles that are very simple, or I still know it, or will be at a certain moment in life, wandering in the head, many years ago, I learned a lot of theoretical knowledge, did not use it, but it is still useful, at some time in the future, at some moment in the future, when it is said to be used, it will be used, just like this very simple question, I also thought about the reason, and finally had my own thoughts and answers.
