I've posted about this before but it really does bare repeating.
Have you ever saved someone's life? No... are you sure?
Would you like to be able to if you needed to? Well really who wouldn't?
Please, please, please go and give blood, (I know some people can't for medical reasons), but if you have no valid reason why not please give it a go. I started age 18, and have donated 11 units since then, however that pales in to insignificance in comparison to the post Natalie has over at The Yarn Yard, please go over and give her hubbie some love, and check out her links if you don't donate.
