Alfred is really a real person;
A surgeon named Alfred found a strange phenomenon when dissecting a corpse: those diseased organs were not as bad as people thought. On the contrary, in the struggle against diseases, they are often more compensatory than normal organs to resist lesions. The earliest discovery was found in the remains of patients with kidney disease. When he took out the diseased kidney from the dead body, he found that the kidney was bigger than the normal one. When he went to analyze another kidney, he found that the other kidney was also unusually large. In the process of medical anatomy for many years, he constantly found that almost all human organs, including the heart and lungs, have similar situations.
He wrote an influential paper and analyzed it from the medical point of view. He believes that the function of diseased organs is constantly enhanced because of the fight against the virus. If there are two identical organs, when one organ dies, the other organ will try to take full responsibility, thus making the sound organ stronger. This is the rudiment of hurdle theorem.
