Blocking drug patents

It is a three-point poison of medicine. It can reduce the sensory field of nerve through pain training, but there must be a reversible method, because no pain is terrible, and the function of living things is constantly evolving or optimizing. If you really need to turn off the pain function, the human body will evolve over time, but for a long time. Before shielding, please think about why it hurts and whether the body is warning itself. Of course, this is against the will. Think again, if there is no pain, for example, if you are touched by a table, stabbed by a knife, or hit by an object, you won't feel any pain, that is, you don't feel any pain, you don't know that your body is in danger, and you can't play a warning role. Then if the infringement is further increased and there is no physical warning, it may be terrible. Reducing the pain area is not recommended.
