At 32 David, who lives in Tamworth, was diagnosed with polycystic kidney disease, a genetic condition that causes multiple cysts to develop on the kidneys.
The kidney is normally the size of the palm of your hand and both his were the size of watermelons – with a combined weight of 8 kg.
In February 2011, David, aged 54, had an operation to remove both kidneys and was in his words 'utterly reliant on a dialysis machine', routinely having dialysis at home three times a week for four hours each session.
David said: "I was told the waiting list is about three to four years but I was lucky and received a donation after 18 months.
"When we got the call, my eldest daughter took me to hospital and it all happened so quickly that my wife, who was out at the time of the call, missed the operation completely. We had arranged a family meal for my birthday that evening but that had to be put on the back burner!
"The loss of life of the person is of course very sad, but the donation has made a big difference to my life, and that of my wife who took time off work to help with my dialysis.
