Today I chalked up blood donation #48 since moving to Charleston. That makes it 6 gallons of blood that I've donated over the past 10 years. Counting donations back home, I think I'm just over 10 gallons over my lifetime. That's almost 38 liters! The average person has about 7 liters of blood, so I've donated my entire blood supply 5 times over in the past 20 years or so.
So how many are you up to now?
