4 minutes and 18 seconds was all it took.

That's all it took to hopefully save a life, or help someone recover from a major accident or operation.

I spent longer having my cup of tea and biscuits afterwards whilst chatting to other donors.

I love the thrill and satisfaction of donating blood, it sort of counteracts all the shit things I do in life!!!

Well, it makes a small dent in the balance of things.
