If you are a working adult, you don't defecate in front of others. Even if you want to pee, poop or fart, you hold it in. It's common sense. However, if you are in a place where this behavior is not only tolerated, but even welcomed, the situation is completely different. Just make sure you're healthy and in a place where it's okay to let it go. We invited Misao Kuroda to give it a try.
