We measure the time it takes for any property in the body to decay through its 'half-life'. It could take an infinitude of halves before it is considered almost gone. Even if we keep dividing things in two, one part here and another somewhere else, it still feels like it will never leave us entirely. Maybe I am thinking too much. I can think of many simpler things halved, like a peach this morning: cold and sweet. It reminds me of spring, again.
