Organ Donation

Chris Kemp, who gave a kidney to his son, Oliver.

"Having only one kidney certainly doesn't stop me doing things. Oliver and I joke about the transplant sometimes. I tell him he's had my money - he might as well have my body!"

Tom Bortey (right), who received a kidney from his brother George.

"If my brother hadn't donated his kidney there would have been no hope for me. I owe it to other black people to tell them our story, so they can think about making donation."

Paulette Cain, who donated a kidney to her husband, David.

"People say it was a generous thing to do. However, in reality, I wanted it for myself and Jade, our young daughter, as much as for David because the strain on our lives was so great."

Barbara Ryder gave a kidney to a stranger, Andy Loudon who was suffering from polycystic kidneys.

"The kidney was literally a spare part which you can do without. I thought 'Good. At last I can do something physically useful."
