What is happening?

Got word tonight that pops is back in the hospital.  I think he only got out last Friday and now he is back in.  I don't know.  His blood count is down again.  Somewhere he is loosing blood.  They are going to scope the lower portion of the digestive system tomorrow.  Hopefully something will present itself and this problem can be figured out and corrected this time around.  It would just be nice to know what is happening.
