This virus spreads extremely fast and can easily infect the human body. Once inside a human, the virus automatically detects the number of cell divisions and, based on the various phases of cell division, determines the age of the person, already possessing preliminary intelligence. Once it discovers that a person is 60 years old, the virus immediately strikes, causing death within a week. However, if the infected individual is under 60, the virus remains dormant in the body, waiting until the person turns 60 to attack.
