Nick ~ I have been saying that for 10 years now but I am still clonking on. I had a heart attack when I was 41 and can remember hearing the doctor in A&E telling the wife, just the other side of the curtain from where I lay in one of their cubicles "You must prepare yourself ~ He is unlikely to reach 42"
I shall be 61 in July and we have had three children since that medical pronouncement.
