A function to the toilet
Recently, toilet paper was disappeared from all the street. The same time, the toilet of our restroom on the second floor was replaced to the new one.
When I used the toilet, I was surprised. How many functions it has!
Then, I've got an idea for a new function to the toilet. This function is as follows: It shows appropriate recipes for each person's health automatically, that is revealed from conditions of one's feces.
What do you think?
