Like Lady MacBeth, I've been having hallucinations about blood today. <g>

But I think I've got it figured out where I was confused about red blood
cells and their lifespan.  Human, afterall.  I must have been thinking about
platelets whose normal lifespan is about 8-10 days (but which lifespan is
reduced in stored blood to about 70% at 5 days).

Dang, it's hard to retrace the veins of thought from which any of this
entered (or got confused) in my mind, but I think it was from reading last
year about "sticky platelets" and fibrin/fibrinogen and their relationship
to CVD.  I read platelet, but thought red blood cell.

Now I wash my hands of this topic.  LOL.....aren't you all glad?!!
