I fail to understand how this can be an unimportant topic when, on an average, we visit the toilet 2500 times a year, or 6-8 times a day. 
Ninashindwa kuelewa ni kwa jinsi gain hii inaweza kuwa mada isiyo na maana wakati, kwa wastani, huwa tunakwenda chooni mara 2500 kwa mwaka, au mara 6-8 kwa siku.
