Special care may be taken to avoid occurrences or reminders of the number 4 during everyday life, especially during festive holidays or when a family member is ill. Mentioning the number 4 around a sick relative is strongly avoided. Giving four of something is strongly discouraged. Elevators in Asia and Asian neighborhoods often skip the 4th floor. Military aircraft and ships also avoid the number 4 (such as in the South Korean and Taiwanese navies). Dates such as April 4 are also thus avoided.
