Oh the Irony

I was having a discussion with my friend today about donating blood when it dawned on me that while I can donate blood to approximately 86% precent of the human population since I'm O positive I can only recieve blood from someone whose either O positive or O negative. Believe me the irony is not lost on me. The only comforting fact is that type O is a realitively common blood type. Regardless I think I should start be judiciously selfish with my blood, maybe start up a reserve in my fridge Cosmo Kramer style.
