Bathrooms in Shanghai, China have been equipped with state-of-the-art technology, including warning systems for people who use the facilities for too long.
They all come equipped with high-tech features such as monitoring and controlling the odor, tabulating the number of visitors and adjusting water levels.
One feature that is drawing much attention online is the timer that tracks how long a visitor uses the bathroom.
If the visitor stays inside for longer than 15 minutes, an alarm will be sent to a worker who will then check on the person.
