John Filicetti, 53, has given a total of 243 times adding up to over 30 gallons of blood during his lifetime -- so far. He continues to donate every 56 days, which is as often as he's allowed to do so.

It started out originally as a competition with his father, who organized blood drives. After that it kept going when his son was diagnosed with hemophilia, and today he gives just for the joy of giving. He says "It's just such a little bit of your life you're giving, time-wise," and he also says he can't understand why more people don't donate.

It takes less than an hour to donate blood, often 30 minutes or less. When is the last time you gave blood?
