Chalked up my 16th blood donation today since moving to SC. That means over the past 3 years or so, I've donated close to 8 liters (2 gallons) of blood. It also means I've made 48 or 49 donations since I started donating blood. And since each donation can be used up to 3 different ways, that means I have probably helped as many as 150 people!
BTW, I nabbed the image from the givelife.org website...hope they don't mind.
