Quote from QuasarX
I haven't and don't intend to. Simply put, I think my body works better if I keep my blood inside of it...
Not really. In the long run your body will profit more from producing new fresh blood once in a while.
Quote from QuasarX
...and I see no point in giving it away to people I don't know, especially when those people might then go on to do things I wouldn't approve of.
Consider that even your acquaintances, friends and family may get into the need for a blood transfusion and if the hospital happens to be out of blood they will be just as screwed as the people you don't care about.
Quote from QuasarX
Besides, I don't regard death as something to be feared or postponed, as many people seem to. As far as I'm concerned, death is just a necessary part of life. We literally couldn't live without it.
While it's true that death is necessary and not fearing the inevitable is wise, there's nothing wrong with postponing death for as long as possible. Lifetime, being limited, is valuable and thus to preserve. You probably don't disapprove of breathing and eating, which is postponing death on a daily basis. Blood transfusions are the same, just not as established.
