I find now the need to go sniff my guitar to see if it has any poo odor

Dan, in the days before smoking was banned in public areas in the UK, I used to play in a Memphis/New Orleans-style funk band in a bar in Brighton called The Lion & Lobster. I didn't smoke - haven't smoked for over 40 years - but I used to wake up the next day and take my guitar out of its case. It reeked of tobacco!

I think poo is probably better for you... particularly folk poo... :-)
