I very rarely smoke a pipe, usually only when around others that smoke a pipe. Think I'm on my 9th pipe. I have given most of them away but have a few I've kept for myself.

Programming, replay old pc games from the '90s, check out new music, explore business ideas, crafts, reformat a laptop and put a different OS on it, pick a Zelda game and start a replay, do paint touch-ups on the walls.
