Love may be boundless and abundant, but time isn't. Time is finite.

We now have political chaos. We've got parties in Ireland saying they want to merge with Northern Ireland. You've got parties in Scotland saying you want to leave the U.K. You've got the Spanish government saying it would like to take ownership of Gibraltar, which is a British overseas territory...

Loss aversion is a really disproportionate anxiety about stuff that doesn't matter very much. So for instance, if you lose $5, you feel really bad about the $5 you've lost. You're cursing yourself. You're going through it again and again. If, on the other hand, you find $5, you go - hey, great, five bucks. And you've forgotten about it really quickly.

In many ways, love seems to be totally divorced from economics. But then you realize - well, the stakes are high. This is something that matters to us. We're dealing with scarcity.
