Mind blowing information! I salute to the writer of this remarkable article. It is said "no pain, no gain". Pain is important because it is associated with our own existence. We cannot realize our own existence if we don't feel pain. When we feel pain, we try to remove the things or get rid of the circumstances that causes pain.
However, sometimes pain becomes too painful. Some people feels excruciating pain without any reason. There are also some medical conditions in which the patients' life become hell. Also, our society gives us enormous pain and sufferings. So, excess of pain is also bad. In fact we should live in such a way that we may cause no pain and sufferings to other people.
CIPA (Congenital Insensitivity to Pain with Anhidrosis) patients are mostly in Japan. Is this connected to genetic mutation caused by nuclear bombing during world war 2.
