Gave blood this evening and completed my 8th gallon. Not really all that much, considering that I've been donating for over 30 years -- works out to about 2 pints/year. Even allowing for a decade or so of inactivity, it still comes out to only three or four pints/year. At the legal minimum of once every 8 weeks, one could theoretically do 6/year.
Still, it's something of an accomplishment.
