I'm regularly surprised by how many people manage to shit themselves, and how it's common enough that people have a casual laugh over their "shat myself" stories. I feel left out. I laughed so hard I peed myself once when I was 5?
I have IBS, and while I've had many close calls I can proudly say that I've never shit myself. As someone that's basically a flight risk for accidental pooping, as well as having heard these stories before in-person, I often wonder if more people have stomach/bowel problems than they'd like to let on.
