MORE ON AGING AND EXTENDED LIFESPANS: Here’s an interesting Slashdot thread about the Methuselah Mouse Project and related items. But this post is my favorite bit:

Whenever the subject of interfering with nature / the divine plan comes up, I refer to this response which I heard one day in an interview: the single development in recorded history which has most vastly extended lifespans was the invention of the toilet… yet you don’t hear people going around debating the morality of having toilets.

This reply is pretty funny.
