Oh, you doctors and your scales. In an effort to pseudo-quantize everything, perhaps you’ve gone too far. What follows is the Bristol Stool Scale, which goes waaaaay beyond “#2.” From Wikipedia:
It was developed by K W Heaton and S J Lewis at the University of Bristol and was first published in the Scandinavian Journal of Gastroenterology in 1997. The form of the stool depends on the time it spends in the colon.
