Introduction

Dr. Abdul Alsayy: Crap is what gets left over when your body processes food, but it's actually pretty complex. 25% to 55% of the solid dry biomass of scat is made of bacteria from your large intestine. Hard stools usually mean you're not consuming in a fiber-rich way or are severely dehydrated. The smell of doodoo can be so bad that we've developed a life or death need to distance ourselves from it.
