Unsolved mysteries in Asia

I was concerned about 2 mysteries: What is the meaning of life and what is it with Asian toilets.
Thanks to Douglas Adams, we know what is the meanign of life: 17

Now, here is the thing,... you average Asian toilet is 1,5 meters x 1,1 meters. A standard door is 90 cm wide. Why is it that all toilet doors open inwards? Basically, the door will hit the bowl when opening. Why? Basically, it means you have to stand on the bowl to open / close the door.
(I would give you a drawing, but I failed in art classes). I think you get the drift...

Simple solution: let the door open outwards. Unless people enjoy a limbo to get in and out of the cubicles. Maybe the idea is to entertain and challenge the user?

Any thoughts are welcome.
