The anti-aging has slowly growing from the 1970s and is nicely coming along. With recent advances on stem cells and other medical breakthroughs the goal is coming closer and closer each time.
Now, the cell-printing and tissue growing techniques have advanced enough, acording to Ouroboros that maybe all those anti-aging drugs that really lenghten our lives aren't that far away after all. Below you can see a video presentation from Sally Dickinson that demonstrates the first transplant of a tissue-engineered airway, which took place in June 2008 explaining the whole procedure. Using a donor trachea, they first treated it to remove all the donor's cells; they then took some stem cells from the patient's bone marrow, turned them into chondrocytes, grew them up and seeded them onto the scaffold; finally, they transplanted the engineered trachea into the patient.
Of course, that only means that there are more moths to feed and less people to work while number of elderly people grows bigger. But that is whole another issue to deal with in counter means. For example, we could extend the working period of a person since average lifespan of a person lenghtens and elderly people have less health problems.
