Different development itself runs the threat of making life shapeless.

One of the things that's crucial to me about love is that it has to be in the moment.

I don't want to say that the creativity would give out - I can't imagine what argument I would bring forward for that. But I think that there's something on the individual level that's a limitation.

If you're immortal, you can imagine being sad or grieving if a lover leaves you. But if everyone were immortal, then that leaving isn't necessarily forever. There's always a chance that you get them back somewhere down the road - you know, in 5, 10, 20,000 years. So I think that the urgency of the moment gets sapped.

One of the things that makes the uncertainty of death so difficult for us is that we could be involved in a project and then, suddenly, it's cut off. And it's cut off in the midst of our involvement, so that we don't have a chance to see it through, to accomplish what we might accomplish.

Love is not a promissory note.
