I don’t think anyone has ever asked me this question, but I do know from other advocates that this isn’t unheard of. Quite frankly, I think this question is rather bizarre, and its implications are even more so.

In this article, I’m not going to question the assumption about the inevitability of death; rather, I will take it for granted and try to explain why I think it has no relevance whatsoever to whether or not rejuvenation is worth pursuing.

I find there’s a certain similitude between the questions “Why rejuvenate your body if it’s going to die anyway one day?” and “Why clean your house if it’s going to crumble to dust one day?” An obvious answer to the latter question would be: “Because in the meantime, I’m going to live in that house, and for as long as I do, I’d like it to be clean.” If you think about it, this makes for a pretty accurate answer to the first question as well, so long as you replace “house” with “body”.

Jokes aside, the implied assumption behind this question seems to be that, so long as life doesn’t last forever, improving its quality and quantity is pointless. (It doesn’t make much sense to distinguish between quality and quantity in the case of life, because as we have discussed in another article, it really isn’t possible to extend the average lifespan without significantly improving health, and vice versa.)

If this assumption were true, it would also apply to a number of commonplace things and situations that we wouldn’t ever dream of considering pointless, even if we were more than a few marbles short of a bag: if death is inevitable, why get a flu shot? If death is inevitable, why undergo heart surgery? If death is inevitable, why looking before crossing the street? If death is inevitable, why eat? And so on. The answer to all these questions is the same: for as long as we’re going to be alive, we’d like to make our lives as enjoyable as possible; and not only do all those things improve the quality of our lives, they make our lives last longer than they would otherwise. Who knows, maybe it won’t last forever, but a longer, more enjoyable life seems preferable to a shorter, more unpleasant life.

As an extreme example, if the assumed finitude of life made improving and extending it pointless, then we could generalize the reasoning and conclude that, since the universe seems doomed to die in one way or another, perpetuating the human race and improving the lives of its members is pointless too! Now that’s a seriously pessimistic outlook on life.

My opinion is that, if life is finite, there’s no reason to make it shorter than it has to be, and, moreover, there’s no reason to make it less pleasant than it could be. If rejuvenation biotechnologies reached their full potential, we could be able to always enjoy youthful health no matter our age for as long as we live, however long that may be. Regardless of this length, I see no reason why the final years of our lives should be spent in the company of disease and decrepitude.

And if, one day, the Big Crunch or something else comes to put an end to our lives, so be it. Death of the universe preceded by good health sounds like a better deal than the death of the universe preceded by cataracts, for example. At least we’ll be able to see what’s going on!

About the author

Nicola Bagalà

Nicola is a bit of a jack of all trades—a holder of an M.Sc. in mathematics; an amateur programmer; a hobbyist at novel writing, piano and art; and, of course, a passionate life extensionist. After his interest in the science of undoing aging arose in 2011, he gradually shifted from quiet supporter to active advocate in 2015, first launching his advocacy blog Rejuvenaction before eventually joining LEAF. These years in the field sparked an interest in molecular biology, which he actively studies. Other subjects he loves to discuss to no end are cosmology, artificial intelligence, and many others—far too many for a currently normal lifespan, which is one of the reasons he’s into life extension.
