If you see the muck that accumulates in the shank/mortise you'd be horrified. I'm not obsessive about cleaning - always a couple of pipe cleaners, then doubled over to scrub out the bowl.Me either, it baffles my mind to see the lengths people go through to sanitize and sterilize their pipes after a smoke. That's like breaking in your pipe every time you light up another bowl.
Recently I took apart a pipe I'd owned for 40 years and was appalled at the state of the airway.
