A colleague (non-smoker) acquired a pipe. He called it his "thinking pipe". I suspect it may have been to annoy his wife.
I mentioned this to my family. My son thought it a good idea, so bought me a pipe. It occurred to me that sucking air through a dry peppermint teabag would give a pleasant, though delicate, mint taste. It did.
So, I have a mint flavoured thinking pipe. It is strangely comforting...
