I am truly honored. I hope every blood donation I gave was able to help save a life. I always wonder about how the recipients are doing, and what circumstances led them to need a life saving blood transfusion. The blood bank keeps all of that private for security reasons, of course, along with the name of the donors who donate. I just hope it all helped.
It’s still exploitation. They’re making profit off your generosity. Loads of it. Personally I sell my blood. Still get to help the people in need, but at least it’s a more honest transaction.
