Did you ever notice that Valentine's Day and Venereal Disease share the same VD abbreviation? If next year's Valentine's Day is anything like the boring dateless one I had this year, that would be a good thought to remember. Equating the day with a reminder that casual dating can be a bad thing makes it a lot easier to deal with any lack of casual dates.
And now for something completely different. Immortality. I hear time and time again that living for an extremely long and indefinite period would eventually get extremely boring. So boring that you'd want to die because there's nothing new to do.
I don't agree. With my imagination and a new perspective on the possibilities, I'm convinced I could come up with new activities to keep my interest for millennia or longer. Imagine taking a few hundred dollars every so often and investing it in a relatively secure means, eventually that money (barring the downfall of an economy or some world shattering disaster) would provide you with more funds than you could ever hope to spend.
And that's just for starters, for the first few centuries. Another thing is to spend a few decades studying whatever you feel like. As your plans get more far reaching, maybe you'd initiate the genetics experiment on human longevity that Heinlein detailed in Methuselah's Children. That way if you wanted some similarly long lived companions, you eventually could, even if you had to find another way to achieve it.
Or maybe you'd eventually find the change of faces refreshing for a time, and rather than one long lived individual you'd enjoy being a sort of patron to an entire family line or two. It might be fun to watch how each generation is both the same and different, in so many ways.
Maybe at some point you'd amuse yourself by maintaining a museum, so much more interesting for the periods you've lived through, and a good way to learn about the ones you haven't.
And just imagine the technologies. Things I thought up for science fiction stories in high school are coming about much sooner than I expected, and some things I didn't even take seriously are now being seriously researched. Less than two decades later, things I never even hoped to see for another two decades to come are already coming to be. Sometimes I'd idly thought how nice it would be to have a camera in my eye, just to catch images of places, people, and events that I might not be fast enough to catch even if I'd had a camera handy. Or maybe a recording camera, so I could decide to save images up to an hour after the fact. Well, it's not implanted, but the technology to do it exists, all I need is the money to buy a portable computer and a wrap around eyepiece, and it's less cumbersome than the heavy and bulky eyeglasses I was wearing just a few years ago. Glasses keep getting lighter, but if eye surgeries keep improving soon I may not need them. Yet another thing I didn't expect. I thought I'd be stuck with glasses til implants were possible. (they're not yet, but they will be. Maybe within a decade, but definitely within two or three)
Living effectively forever could be fun, for me at least. I have the right perspective even if most other people don't.
And besides, by looking so far into the future for my own personal plans, I'd quit fretting about silly things like one day of any particular year where I don't have a date.
