brooklynpiper, welcome aboard. Brooklyn's a vibrant place to live. You raise an interesting question about pipe smoking and circadian rhythms. I seem to start a pipe only after noon, as some people have a specific hour for drinking, "when the sun is over the yardarm." I seem to bustle around with chores and activities and only settle into a pipe after lunch, and/or on into the evening. It's a way of collecting my thoughts, and making sure I take the opportunity to have a few thoughts.
