Bloody 'O' my goodness!

Do you know your blood type?

According to a chart on blood types (source: Yahoo, I think), the following is noted by me (sorry, my attempt to copy it went haywire):

O- or 'O' negative to be precise, is the most versatile blood type, being acceptable by all blood groups. But unfortunately, on 7% of us have it. Though O- is the most versatile blood type to others, it can only accept its own type! By this fact alone, those people are truly selfless! Or unlucky, depending on how we view it.

40% of us have O+ or 'O' positive which blood can be accepted by 50% of blood types (AB+, A+, B+, and O+).

The second most common blood type is A+, with 34% occurrence, and is fairly acceptable by AB+, AB- and A+. They can receive 50% of blood types (O+, O-, A+, and A-).

Those with AB+ are the luckiest, being able to receive all kinds. But there are only 3% of us. But AB+ blood can only be used by its own type (selfish?).

Most rare of blood types (1% occurrence) are B- (can accept only O- and B-) and AB- (can accept O-, B-, A- and A+).

The remaining blood type is B+ which 8% of us have it, and acceptable by AB+ and B+ only. They can receive 50% of blood types (O+, O-, B+ and B-).

(actually got pretty confused! hope I've got the facts correct)
