Hi
Nice thread and to a whorthy cause, but not wanting to be a wet blanket but If you are already there giving blood take the time and register to be a donor.
I have just gone through a heart transplant, been i the hospital 3 weeks and looks like I can get the weekend at home... awesome as I have been climbing the walls here.
Giving blood is great but have a think about giving someone a new life as well
I thought this pics sums it up pretty well
