Where do you get this idea that the Last Dragonborn would live until another one is born?

Standard Dragons can be killed by mortals, but their souls remain intact. Only Alduin is unstoppable. But why do you think another DB needs to be conceived. The Last Dragonborn is mortal, which means they age like everyone else. What happens to the DB's soul, is not explained. Not that I'm aware atleast, but I might be wrong.
