I have given blood in the past...it's been so long though I can't remember...but when I did I never really thought about it. I mean how that pint of blood would affect someone else... not until I was on the receiving end. Last December I needed 4 pints...all at once... there meant four people literally saved my life...did they know that their gift was that important? I know I didn't really think I was saving a life...I was just giving blood to help someone else. I will never know who these people were but I am so grateful that they gave me the gift of life.
