A German Interview with Aubrey de Grey

A translated interview with SENS Foundation co-founder Aubrey de Grey: "I have identified seven types of damage [that cause aging]. In five cases we can repair the damage in my opinion, by replacing irreversibly damaged cells by stem cells, or when garbage accumulates, we will remove [it]. In two cases, we need to engage in gene therapy, for example, through new DNA counteract mutations in the mitochondria. ... We should intervene as little as possible in the metabolic pathways themselves. This is too complicated, we do not know enough yet about it. I prefer the regenerative approach, the repair and maintenance. It is [sufficient] to repair the damage after it occurred. In this way, we do not [need to] understand all the molecular details and how they come about. But we have to intervene before the problems get out of control. ... A simple example is the stiffening of the extracellular matrix - this is the fibrous scaffold between cells. The stiffening occurs because certain molecules network with each other. There is a principal [agent], a molecule called [glucosepane], which has the largest share of the networking and reinforcement. We must find a way to break up about two-thirds of them again. If we break these reinforcements, it would eliminate about half of the damage. ... I think the probability is about 50 percent, that all of these therapies in 25 years actually show the desired results. The average life span might then be [increased by] about 30 years."
