Blood

I came upon an interesting fact today while browsing throught www.heart2hearts.co.uk. It sems that the average by pass patient requires between 2 and 4 units of blood during the op. To be honest I wasn't sure how much a unit is, but it turns out that it is 454ml or nearly a pint.

My wife is a blood doner, and has been for a number of years but I can't donate having the health I do. It just struck me that there must be thousands of people like her who go to the blood centres and give blood for people like me to receive.

If you're one of them - thank you!
