The joy of life
In a hospital in San Diego, a border city on the west coast of the United States, William? Matthew. When the sun shines into the ward from the south-facing window, Matthew begins to meet the pain attacks from different parts of his body-pain always comes in the morning. During the nearly one-hour torture, Matthew couldn't turn over, wipe sweat or even shed tears, and his lacrimal gland (xiàn) shrank due to the side effects of drugs.
The young female nurse covered her face with her hands for Matthew's pain and dared not face it squarely. Matthew said, "The stabbing pain is unbearable, but I am still grateful-the pain makes me feel alive."
During Matthew's first few years in hospital, he felt nothing, no comfort or pain. Under the careful treatment of doctors, some nerves have been regenerated, and a "pain" signal is sent to the central nervous system (shū) every morning.
It is absurd for ordinary people to seek happiness in pain. But putting yourself in Matthew's situation, we know that this special pain not only brings him joy, but also brings him hope. Of course, an important premise is that Matthew is a strong-willed person.
Matthew has experienced countless unconscious days and nights in the past. If yuán is a broken wall, then the unconscious is a lifeless desert. The sense of pain made Matthew experience "existence". In a sense, this is even a manifestation of value-the embodiment of medical value and rehabilitation value. Of course, Matthew is not a morbid sex maniac. He regards pain as qi activity, then recovers and enjoys all the feelings enjoyed by normal people. No one can guarantee that poor Matthew will make it to this day, but he and the doctor are working hard in this direction, so he hopes that the pain will come as scheduled the next morning.
