There are four different blood types: type-O, type-A, type-B and type-AB. Type-O, the most common, is known as the universal donor because any person can receive a blood transfer of type-O blood. Type AB is known as the universal receiver because type-AB can receive a blood transfer of any type of blood.

History of Haiti. The recorded history of Haiti began on 4 December 1492 when the European navigator Christopher Columbus happened upon a large island in the region of the western Atlantic Ocean that later came to be known as the Caribbean. It was inhabited by the TaÃ­no, an Arawakan people, who variously called their island Ayiti, Bohio, or Kiskeya (Quisqueya).
