I totally recommend giving blood. Remember the person you save, might just be you! I am B- and it is one of the more rare blood types, so I try to give every 56 days. I will warn you that once you’ve given blood, the red cross will hound you until the day you die to do it again…maybe even after you die, but knowing you saved someones life (or could be saving your own) is well worth the phone calls.
