Meh! The less cleaning to do, the better (5 less minutes of cleaning per day = 1825 hours saved over 60 yrs...so, I'd rather pee in the dark and take a sabbatical and relax - doesn't stress causes health problems too anyway?
)...besides, there's no telling what you can die from as RC-1162 said above...or you could simply fall down the stairs in the dark without even having had the time to pee...
