You can easily donate blood, plasma and platelets. Due to blood shortages, donations are always needed. My wife received numerous donations of red blood cells and platelets during chemotherapy treatment, and it amazed me that because of a lack of supply, the blood she received had been shipped to Pennsylvania from Michigan. The donation process is painless, and a typical blood donation takes an hour. Your blood can help up to three patients.
U.S. citizens can visit the American Red Cross website to find a nearby donation center. The International Federation of Red Cross and Red Crescent Societies has a searchable database of their global members.
