It depends on your blood group and the other person's blood group.
Blood group AB positive can receive any blood from any blood group. O Negative can only receive O Negative blood. Serious reactions can occur if the wrong blood type is given to somebody, so the Blood Bank tests donated blood very carefully. When somebody needs a blood transfusion, their blood is sent to the Blood Bank who test it very carefully. Then they send the right sort of blood to the hospital to give to the patient needing a blood transfusion.
But blood type is not the only thing we have to think about. Some diseases and infections are carried in the blood, and the person giving the blood might not even know that their blood is infected, so the Blood Bank laboratories have to test the blood for infections too. Infections might be HIV which causes AIDS or hepatitis among others.
But blood is not always mixed in hospitals for sick people. Often children will make a small cut in their skin and their friend does the same thing. They then mix the blood to become "blood brothers". It has never been a good idea, but now we understand more about the dangers of life threatening infections, children should be warned about it and told not to do it.
If your blood isn't the same blood type (A, B, AB or O), then brain damage or death can be the result as the two blood types will cause many clots to form and stokes can be caused by clots.

Well.. apparently one of you may not be straight. What's the next step after seeing it. "Can I touch it?, Can you touch mine, Stroke it a little to get it up, Wonder what it tastes like? See where this could go. This is not recommended.
too much caffeine for you... people with high blood pressure should stay away from such a combination.
if they put you down, if they aren't happy for you when something good happens to you, if they compare themselves and their accomplishments to you and yours, if you get the feeling that they get satisfaction out of seeing things not go your way, things like that.
It is more common to use "Yours sincerely" at the end of a fan letter, as it is seen as a warmer and more personal sign-off compared to "Yours faithfully."
If a blood cell is put into a high sodium solution it will become crenated (shrivel up). Water will flow out of the cell into the solution. If it is put in a low sodium solution it will absorb water/expand outward. If the sodium concentration of the blood cell and outside environment are the same, nothing will happen.
its checked for high blood pressure which cause problems so they like to check it so if it happens they can put you on medication to fix it
At the end of the sentence.
If you know the name of the person to whom the letter is addressed, then you may use: "Yours sincerely". If you do not know the name, or you are writing to an organisation, then the "Yours faithfully" salutation is the correct form of address.
