Internal injuries and fatigue can cause disease. The human body is like a machine, is a machine to operate and rest, the machine does not operate to rust, a run too long, or use too often, are prone to problems. Everyone from the beginning of birth has a different innate essence, which is given to you by your parents, more or less on those, you do not have a choice, regardless of whether you are willing to accept. Just like every machine has a different service life when it leaves the factory, and it is not up to the machine to decide. So the maintenance of the machine is also to our own body health, this is a lifetime of work, rather than the elderly idle nothing to do. Everyone’s birth is like a factory computer, the initial system is almost the same, after the education, experience, living environment and so on decided that we have a different program to cope with our life and work. And these programs are with the continuous use in the daily improvement and modification. So if you are used to doing something, you will find it easy to get used to it, which is the result of the continuous improvement of your program. Just as our computers are full of junk, our lives are full of useless, negative experiences, memory fragments, etc., and we need to organize and remove this junk on a regular basis in order to keep the computer in our body running well and quickly. In addition, every computer has a lot of unused space, in fact, our own body also has a lot of unused capacity, although people are feeling exhausted to cope with the fast-paced family life, ah, work, ah, in fact, we are using only a very small part of the body’s capacity. We have changed to a new environment sometimes feel uncomfortable, on the fire, in fact, it is as simple as to your computer to enter new information and write new programs, as long as it is not paralyze their own virus, once the new program is established, you will find that you actually have their own dare not imagine that they did not have the potential and ability. The smooth running of all these things requires us to constantly recognize ourselves and use this body machine of ours, and even more importantly, we need to take care of it and maintain it.
