To age gracefully, without becoming weak, this is the dream (and likely reality) that Aubrey de Grey lays out for us.
At the age of 60, you may receive modern genetic therapy and rejuvenate your biology to that of a 40 year-old. After another twenty years pass, our rejuvenation technology will be even more advanced and could possibly enhance your life even longer.
The idea that, as we age, we we become a burden on those around us will become a thing of the past. Losing 100,000 people a day, worldwide, to age-related deaths will be a thing of the past.
De Grey has been at the life extension game for decades. He is a proponent of all sorts of gene therapy techniques and, according to him, we are very close to a magnificent breakthrough.
The SENS Research Foundation, a company of which de Grey is the Chief Science Officer, has already tackled seven severe, degenerative aging diseases, using rejuvenation biotechnology.
