Apparently only about six percent of the population has A negative blood type, guess that makes me slightly special. By special I mean, it may take doctors a minute to find me some blood when I finally fuck myself up something good, because I don't want any of that dirty, poor people O negative blood.

The negative/positive aspect of blood type has to do with something called Rh factor. If your blood has the Rh marker, your blood is whatever type plus positive, without the Rh factor, your blood is negative.

Even my blood is negative.
