Congrats to your friend, I hope he does well!

I used to hang out with a woman who worked on a transplant team when I lived in Boston. When she was 'on call' she was REALLY on call and often had to go at the drop of a hat. I always thought that was such an amazing job though!

I also know a woman who donated one of her kidneys to her husband. They were 'the perfect match' in more ways than one!
