donation 112

I gave my 112th blood donation today.

They take half a litre every 56 days.

Someone asked me, “Is that a pump?  Are they pumping it out of you?”  No!  It’s not a pump!  It’s just a bag of blood sitting on a platform that moves back and forth every few seconds to stop the blood from coagulating, or whatever blood does when it sits still.  The heart is a pump.  It pumps it all around; and if you put a hole in a vein and let it out into a bag, your heart doesn’t know the difference.  It just gets pumped out.  No biggie.
