Peeing and Dessert

Is holding your pee for a long time like saving dessert for last? Is it like eating all the cereal bits so there is only a lake of tasty marshmallow rafts left over at the end? Is it like nibbling the chocolate off your candy bar, leaving only the innards exposed for consumption? Well is it? Is the sweet treat of a pent up bathroom stop like unto these habits we humans have? Some of use just eat and some of us just pee. But some of us like to save the best for last. So are we practicing restraint and creating an enjoyable finale? Or are we simply increasing the chances of a painful and awkward urinary tract infection?
