I first took up the pipe in the early '70s when I was at university, so the first part is mostly true.
When I took up the pipe again a few years ago, my wife had become very intolerant of tobacco smoke/odour. So other than coming out to the verandah or backyard to see if I'd like a cup of tea or coffee, I get to spend a couple of hours of solitude to read the papers, ponder the mysteries of the universe, chill out - whatever.
It's my down time and wonderfully calming and therapeutic.
Sam Sharron nailed it in 1946 !
