Shortly after blogging yesterday I had the news that a friend of ours had died. Last year he was taken into hospital with suspected appendicitis, but the exploratory operation revealed bowel cancer. 6 months chemotherapy followed, but to no avail. He and his wife are both GPs, and kept themselves very fit, walking, cycling etc, didn't smoke, ate properly, weren't overweight, and were up-to-date with with any tests. He was a very brave man who refused to give in, and only last week was walking his dog several miles daily. It seems very unfair.
