I think it comes from living in an era when things seemed more transient and ephemeral. If you didn't catch it, it might be gone forever. As Roy Batty said, "all those moments will be lost, in time, like tears in the rain". In those days, when a movie left the theater, you might never see it again, or so we thought. There are songs, that I heard on the radio, that I didn't find again until 25 years later, and only because of the internet. I've also found books that I searched used bookstores for decades to find, and did not, until Amazon.

Oh wow, how amazing is it that after decades, you finally do find what you're looking for :-)
