World Blood Donor DaySerious diseases, complicated operations, serious accidents: Again and again bodied people are just now suddenly dependent on foreign blood. Since the “lifeblood” still can not be produced artificially, the required amount of charitable healthy people must be met. Unfortunately, the need for blood is growing much faster than the number of citizens willing to donate. The one responsible for this is the aging population, on the other hand, the development of new medical therapies, in which blood is used. Currently, only one in 50 Americans donates blood regularly. For comparison, about 15,000 blood donations are needed to meet the needs of American hospitals in one day.
