twitter, they sing "see you" to the day that is making place for the night. The nightworker is preparing his sytem for the night.
He takes his breakfast and has to cough hard as his intestines react on it. The intestines that are not helped to digest by movements of legs, will have a hard job to do.
This job will be much easier if he has the possibility to go for a walk so his legs are used in a normal function.
The physical body does not always react the same way. It has an other system in the night than at daytime. In the East this is known and can be learned as there is a clock of the organs.
This tells at what time which organ is having his priority. If one uses this clock to influence the organ, the influence will be much stronger than if the organ is treated 12 hours before or later.
At that time the organ will be in the state of less activity so it can recover from the work at the priority time.
People that changed their system, will not have breakfast but eat at night. That is the time that normaly the intestines have their recovery time.
By changing the physical system, one can use his energy different without complications. The patient in coma had to do so, to be able to keep his physical body alive. By changing his system into an autonomic system that does not need food, he is not helped by nutricion that can not be digested normal.
