Jon and Erika Donate Blood

The 2 hour experience was a good one for both Erika (daughter) and Jon today who gave blood for the first time. They even signed up to go back again.
Unfortunately, I'm not sure I would be brave enough, plus my blood is very low in iron. But kudos to them for the good deed they did.
Has anyone else given blood before? Or needed blood?
