Now that people are living longer, “would you want to live to 100?” is a question more often asked. Some answer it by saying, “yes, but only if I am healthy and don’t run out of money.”

Many retirees are so terrified of ending up impoverished and in poor health that they never spend more than a tiny fraction of their retirement savings. Health issues in old age can be costly, that’s true enough; it makes sense to have some funds set aside for future medical bills, assistive technology, and so forth. But in the scenario described above—living to age 100 while staying healthy—why would using up one’s savings be seen as a fate worse than death?

Presumably, many people feel that going back to work in old age would be too hard, so any further years of life after running out of money would be a miserable penny-pinching existence. But if we’re talking about living to 100—which, for most of us, is pretty far in the future—then why make such a negative assumption? The current labor shortage is not likely to go away by then, given today’s historically low birthrates, and I expect future employers will be happy to hire anyone they can get. Age discrimination won’t be much of an issue when companies desperately need workers. Medical advances will make us healthier.

Granted, after having been in retirement for three decades or so, our hypothetical centenarian likely won’t have the skills needed to do the same work as before. That prospect might also seem very unappealing to a person who has gotten used to a completely different way of life. In a future economy where workers are scarce and in great demand, however, we may find that it’s easy to start another career designed around whatever new interests we may develop. Maybe we’ll all have bespoke jobs, tailored to our every desire by happily obliging employers. Such jobs would be available to anyone, including older people who run out of savings in retirement.

This may seem a wild flight of fancy by comparison to today’s workplace, which is not far removed from a decade of brutal cost-cutting. Some managers still can’t wrap their minds around the prospect of a long-term labor shortage, and age discrimination certainly hasn’t gone away. Even so, it’s fair to say that any attempt to imagine the distant future is just guesswork—so why live in fear of one possibility when so many other things might happen instead?

That said, I do save regularly in my workplace retirement plan because it’s always good to have savings, whatever the future may hold. In the interest of present-day serenity, though, I don’t worry about how much of my savings might have been spent decades from now. I prefer to hold space in my imagination for a future world with plenty of choices, rather than problems.
