A very Important fact about the human blood

The human body contains one of four main blood types: A, B, AB and O.

Each blood-type also has an accompanying Rhesus or Rh factor of either positive or negative.

The most commonly found blood-type in the world is O positive while the rarest is AB negative.

From the U.S population it was determined that the percentages of blood types were as follows.

O positive ~ 38.4%
O negative ~ 7.7%

A positive ~ 32.3%
A negative ~ 6.5%

B positive ~ 9.4%
B negative ~ 1.7%

AB positive ~ 3.2%
AB negative ~ 0.7%

So what blood type do you have? Are you reasonably rare like me (O-) or do you
have a more common popular blood type?
