I would love to give blood but I'm not allowed to for health reasons so could you do me a regular favour and give blood regularly on my behalf? You can help up to 3 people with every donation and you really can save someone's life! Literally!
The first step is to phone the blood donation bods in your country, they will answer all your questions, set you up with your appointment, you donate your blood, et voila! All done!
Please? For me?
