I keep a daily log of my poops detailing the solidity and size of each specimen. I literally have no use for this data.
It seems very bizarre. Why would you keep a log of your poop if you are not looking for something in particular.
I'm curious what my poop looks like.
That is different.  You should be aware of changes in your poop in case of any health issues occurring.
I've gone a month without a change. I think it's normal but I'm not sure if I have any issues.
Well maybe you should check it out with your doctor so they can see if there is anything wrong. Sometimes our poop is a good way to tell if we are sick.
