It disappoints me that this kind of thing is still news to some people. I value survival (that is, the continued existence of things similar to myself) first and foremost, partly because it's the one thing my ancestors have had in common ever since the invention of phospholipid membranes. The state of Existence is, metaphorically, engaged in ongoing skirmishes with it's various neighbors in possibilty-space, so I'd rather stay away from the border, just to avoid getting caught on the wrong side if it shifts.
