“Gerontologists have been led massively astray by looking for a root cause to aging, when it’s actually that everything falls apart at the same time, because all our systems are interrelated. So we have to divide and conquer.” We just need to restore tissue suppleness, replace cells that have stopped dividing and remove those that have grown toxic, avert the consequences of DNA mutations, and mop up the gunky by-products of all of the above. If we can disarm these killers, de Grey suggests, we should gain thirty years of healthy life, and during that period we’ll make enough further advances that we’ll begin growing biologically younger. We’ll achieve “longevity escape velocity.”
