Giving blood is also a great way to combat a condition whose name I cannot remember, (Hypo or Hyper something,)(hopefully someone on this board will,) in which there is an excess build up of iron in the blood. Persons of northern European dissent, (Scottish in particular,) seem to be prone to this condition which has several effects, lethargy, depression, and several others that I'm sorry I can't recall. It is thought that additional iron in the blood was a good thing hundreds of years ago, when wood was the only heat source, as those with high iron levels in their blood were less likely to freeze to death. (I read all this on the internet a couple of years ago and I'm getting older so my memory is failing.)(Maybe another effect.) Anyway the only treatment for the condition is the age old remedy known as bleeding or bloodletting. So giving blood is not just good for those who receive it! If anyone else knows what I'm talking about, please chime in, it's going to drive me crazy if I can't think of it. Oh, I just passed the three gallon mark.
