but good thing u can give to anyone so if i ever need blood (hopefully not), i know who to call.

oh wait, never mind.. hepatitis.... so you are useless really!!

As far as I know, though, there are some tests that I can do to get a certification from my primary physician that I am able to donate blood. I had been lazy to get that. But if I can't, after the test - what a waste.

But yes, I can only get blood from another O-, but can give to anyone (given I am able to). Keep in mind, hepatitis A is not considered problem in Bangladesh, but it is considered a problem here.

The blood from just anyone cannot be transfused into another. Different people have different blood groups. Variations in the chemical compositions of red blood cells and plasma cause this grouping.
There are many different blood grouping systems, of these, ABO and Rh factor blood grouping systems are important.
There are some compounds called antigens in the cover of red blood cells. There are two types of antigens. One is called A, the other B.
If there is just A antigen in the cover of the red blood cells then the blood group is A, if there is just B antigen the blood group is B, if both are present the group is AB and if there is not antigen the group is O.
Just as there are antigens in the cover of red blood cells there are antibodies in the plasma. Two types of antibodies are usually seen Anti-A and Anti-B.
Opposite types of antigens and antibodies destroy each other. So, if there is A antigen in someone’s blood cells (blood group A), than s/he has anti-B antibody in his/her plasma. Similarly, if there is B antigen in the blood cells (blood group B), there is anti-A antibody in the plasma. If there is both A and B antigen in the cells (blood group AB), than there is no antibody in the plasma, and if there is no antigen in the cells (blood group O), than there is both anti-A and anti-b antibodies in the plasma.
In case of blood transfusion both the donor and the receiver needs to have the same blood group. Otherwise the antigens and antibodies react with each other; the blood cells break and form clots, blocking the blood vessels, which may cause danger, even death.
There are no antigens in the blood group O. So a small amount of group O blood can be given to anyone without any harm. For this reason a donor with blood group O is called a universal donor. Similarly, there is no antibody in the plasma of those with blood group AB. So a small amount of blood of any blood group can be given to someone with blood group AB without any harm. For this reason, those with blood group AB are called universal receivers.
However, it is always safer to transfuse blood of the same group. So the idea is universal donor or receivership is not implemented unless there is an emergency.
Rhesus group or rhesus factor is another important factor to be taken into account in blood transfusion. There is a special type of compound in the membrane of the red blood cell of the Rhesus Macaques: an Indian species of monkey. If the same compound present in the membrane of the red blood cell in the blood of a human being, his blood group is Rh positive, if it is absent, the group is Rh negative.
When we are talking about blood groups we usually mention his ABO blood group and whether he is Rhesus positive or negative.
ABO Blood Group System in the people of Bangladesh:
A: 22.44%
B: 35.20%
O: 33.97%
AB: 8.39%
Rhesus Blood Group System in the people of Bangladesh:
Rhesus Positive: 97.44%
Rhesus Negative: 2.56%

Quoted from the link given before. I think AB+ blood holders are the luckiest, they can receive blood from everyone, and O blood holders are noblest, if they want they can give blood to everyone.

I unfortunately can't donate blood as I don't fit the required weight -_- & I have quiet a few deficiencies. Too bad if someone was dying near me & they needed blood
