For any of you who are contemplating donating a kidney to a loved one, I can only encourage you to do it.
Making the decision to donate a kidney to a friend in end-stage renal failure wasn't easy, but I have never regretted it.
The transplant was four years ago and my friend is doing really well (completely normal!). I have taken up jogging and will compete in my first half marathon this April.
I'm not saying there aren't risks - but it can be the best, most rewarding decision you ever make!
