On 3rd September, 2004, at the age of 63, my father underwent pioneering heart surgery at Harefield Hospital in north-west London which saved his life. 20 years on, he will be celebrating his 83rd birthday in mid-September. With the Harefield Fun Run taking place this week, it feels a fitting way to be able to mark this milestone anniversary and to be able to give something back to and raise funds for a hospital which has done so much for my family and I.
