It is clear to me that your correspondents, Tony Anchors and Derek Honey, are smokers - the poor fellows.

I do feel sorry for them. Please give up as I did in 1972. Believe me, you will feel better.

My dad died in 1960, aged 54. He didn't want to go and cursed himself and all about him until he died. I shall never forget it.
