This is not a bad idea. The constitution of your stool is one of the best indicators of general health status, and changes in your health are frequently observed in the toilet. That being said, almost anything can cause your poo to do unexpected things, from a new med to a stomach bug to a scary movie. So the results of your will be hard to analyze. But it will be nothing if not interesting to see what trends you observe. I hope your s*** journal is a massive success - I would certainly buy one for me and everyone I care about (an EXCELLENT Christmas gift from a microbiologist!) Cheers *raises glass* 🍸
