CAUSES OF DISEASE AND DEATH FROM THE POINT OF VIEW OF PHYSICS can be explained. Except for the disastrous ones, of course. But most often the source is within the boundaries of the system. In a way of interacting with others. Man is a system. To live in yourself, to hide all your problems and experiences, not to open your inner world to anyone and not to be interested in others, energy, to save is a “closed system”. If you do not exchange matter and energy with other systems, "heat death" will occur. The system will collapse; the stored energy will "go rotten". Taking everything to heart is also nothing good. It is an "open system"; in the end, the reserves of energy will run out, and the "cold death" will come. A person will get sick, lose strength, weaken and die. The “pulsating systems” survive and function perfectly; people who can both receive and give. Open borders and close them if needed. Fight back enemies and hug loved ones; to love and not to love, to receive and to share, to let into the soul or turn off contact in time. This is the only way to live long and by force. And successfully interact with the world. And therefore, it is equally dangerous to be too kind and open - or withdrawn and tough. We are alive and pulsating - and as long as we are pulsing, we live.
