Forgive my arrogance, but how does one exactly offer up a portion of his life? Does it commence immediately? Can he select when? Is it towards the giver's own lifespan? If the Rabbi passes away unexpectedly, does the giver recieve his time back? Forgive me, but this is all nonsense. Ancient texts are notable in that they shed light on life as it was then - but no outdated text should be used in this manner for such obvious personal gain.
