When I think about time on that kind of scale it just gives me a headache. I know humans are really good at surviving - hell, you're living proof - but the thought that we could go on so long that all the cities I know are either ruins or lost somehow just... it's a lot to take in.

[He smiles, then.]

Pretty egotistical, I know. Anyway, uh, I know the pool's not goin' anywhere, but right now I think jumping in would do me a world of good.
