Have you ever gotten up from the toilet after a bowel movement and inspected your work? Of course you have. Every guy has, and I’m betting some of you ladies get in on the action too. Have you ever been able to tell, by its contents, exactly what you ate a few hours earlier? Maybe some corn kernels. Some threads of spinach. Some almond slivers or carrot chunks. If you can see it, it means you didn’t digest it, which usually means you ate too fast.
