I make a conscious effort to look at my shits after I finish every time, especially right now while I'm on a bulk.
I always make sure to observe it's texture (solid or liquid), frequency, ease of coming out and smell (does it smell like somebody has died or not).
Now don't get me wrong, I don't get to scientific or anything like that, nor do I record my observations on paper. However, I just make quick mental notes in a split second after I finish as I flush the toilet.
This probably sounds weird to a lot of people, but I need to make sure that things are moving in and moving out at an acceptable rate. Having your bowel movements under control is a key factor to having a high quality of life.
