The HIV, Hep B and Hep C infections probably wouldn't improve one's life span much.
In the early days blood was in short supply and safety wasn't guaranteed. So logically, it was only used in patients that really needed it. Transfusions are safer today (there may be viruses we don't know about...) but blood is still in short supply and there are still rare but life threatening transfusion reactions.
