My dad smoked as long as I remember. He died at the comparatively young age of 64 (a week after his birthday). He smoked a pipe, cigarettes and those small cigars. I don't remember him being well at all. He died of mitral stenosis and bronchitis. He also had a foul temper - probably due to his heart problems.
My mum lived until the age of 90 and she didn't smoke. I have never smoked.
