Ep. #3 - Identity Puzzles and The Ship of Theseus

If we dismantle a ship one plank at a time and replace the rotting wood with new planks of wood slowly over a few decades and then wake up to find that the ship no longer has any of the original parts left is it the same ship?  This is the puzzle of the Ship of Theseus and the focus of this egg timer. During this episode questions about identity over time will float past ships and be applied to persons as well.
