You probably know the quote by Steve Jobs saying that death is life’s single best invention because it gets rid of the old and makes room for the new. This view is the core of another fairly common objection to rejuvenation, codename “cultural stagnation”.

Wouldn’t all those rejuvenated people, however physically young, be always old people “inside”, and drag everyone down with them into their anachronistic, surpassed ways of thinking, making it harder for fresh ideas to take hold, ultimately hindering social progress and our growth as a species? Maybe it’d be best not to take the risk, forget rejuvenation, and be content with old age as it is.

Well, try explaining to your grandfather that the reason he has to put up with heart disease is that we’re afraid people his age may all become troublemakers when you let them live too long.

Today, we take a look at three key emerging technologies that might add extra healthy years to your life by addressing the aging processes directly to prevent or delay age-related diseases.

Senolytics – Removing aged dysfunctional cells to promote tissue regeneration

As we age, increasing amounts of our cells enter into a state known as senescence. Normally, these cells destroy themselves by a self-destruct process known as apoptosis and are disposed of by the immune system. Unfortunately, as we age, increasing numbers of these cells evade apoptosis and linger in the body.

For much of human history, living up to a ripe old age was seen as a gift from the gods, an aberration, or just the product of sheer luck. Given that up to the beginning of the twentieth century many of us succumbed to disease at an early age, being extremely fortunate to live anywhere past the age of forty, it should be no surprise that living a long life is still beatified today as something akin to winning the lottery.

Even when confronted with the galloping pace of scientific advances in human longevity, our historical sensibilities have led us to take a defeatist stance towards the subject: “Even if longevity interventions become available during my lifetime, I am already too late to take advantage of them, so why bother?”

Indeed, this hesitation to see human life extension as a real possibility in our lifetime, dismissing it as a dream belonging to the realms of science fiction[1] and futuristic utopias[2] is not an uncommon one, and as long as tangible rejuvenation therapies do not become available, we will feel validated in our pragmatism.
