A Charlotte N.C. man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. Can the guy be held responsible for the woman’s death? Prosecutors (公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime—even if he or she doesn’t kill someone on purpose.

But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.

Absolutely, no question about it.

The body has a natural protective method called the fight-or-flight response, which was originally described by Walter Cannon，chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the automatic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to early humans. However, in the modern world there is obvious decline of the fight-or-flight response.

The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is poisonous in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death.

By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in excitement or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead.
