Question

Why can we hold our pee until we see a toilet?

Warren, Northwood

Answer

Bladder control is a cognitive behaviour linked to the autonomic nervous system, and is what prevents us from weeing until we see a toilet. When the bladder fills up, it sends a message to the brain to signal that it needs emptying. If necessary, the brain is able to override this message, delaying our urine untill a more appropriate time.
