Looking to be charitable but do not have the extra money to give? Why not give blood?!

To quote the WHO: Blood is the most precious gift that anyone can give to another person — the gift of life. A decision to donate your blood can save a life, or even several if your blood is separated into its components — red cells, platelets and plasma — which can be used individually for patients with specific conditions.”
