Humanity has always battled nature’s limitations — including bodily frailty. For most of our history lifespans averaged around thirty. Now in the developed world they’re above eighty. This reflects elimination of many causes of premature death, especially rampant child deaths. Modern medicine enables many more of us to realize the biological natural maximum lifespan (around 100+ years).
But raising that natural limit is next. That too is a medical problem, and there’s no law of nature barring its solution. Indeed, the same is true of death itself.
telomeres (in red)
You probably won’t turn on the radio and hear, “Scientists today announced a cure for death.” Though lifelong shortening of telomeres (a part of our chromosomes) seems somehow critical — when you’re out of telomeres, you’re out. And there actually is a pill to halt their shortening. Unfortunately it gives you cancer. But maybe, if that can be solved . . . .
But conquering death will likely be more gradual. And not all medical.
And nothing could more dramatically change the human condition. Knowledge of mortality has always shaped how we live our lives, so integral to our psychology it’s actually hard to imagine its absence.
Take risk. In many of our activities, risk of death is not zero. While it’s not as though we don’t highly value our lives, knowing we’ll die in the end makes such risks psychologically tolerable. Lack of a clear “term limit” will surely change that. Will people cocoon themselves in fetishing safety?
Remember Methuselah living 969 years? His kids and grandkids lived to similar ages. The Bible doesn’t mention this, but all those generations would have been hanging around together (at least until finally wiped out by the flood). What will our families be like when you have hundreds of living forebears and descendants?
Meantime, people who basically don’t age or die probably wouldn’t “retire.” Their continuing economic productivity will sustain and extend global prosperity. Maybe sufficient to obviate the mentioned inequality issue.
And what about religion? Evolution seems to have somehow made our minds susceptible to mystical religious ideas. Rationality enables us to move past them, as science progressively answers the world’s mysteries. Yet still, many people fend off science (evolution for example) in order to hold onto religion’s promise of an afterlife, its “killer app.” Even while having their doubts. What people think they believe may differ from what they truly believe. Those professing belief in Heaven struggle hard to postpone going. Because the promise is inherently unbelievable (and deep down we know it).
Well — I’m 71, and immortality probably won’t come soon enough to save me. But my daughter is 25, and I tell her that if she makes it to 100 — highly likely — by then she’ll be home free.
