We may not give them the importance they deserve, but toilets are fundamental to our daily lives and our health. There are two "golden rules" that articulate their usefulness: they 'separate' us immediately from our waste, and they transport them for treatment, preventing them from contaminating the environment or making people sick.
In addition to being a good place to think about new ideas, browse Instagram, and answer emails, the toilet helps us stay healthy, an attribute we take for granted until we lose access to it.
