You're not paying attention. The degradation we associate with aging is process of molecular 'damage'. Scientists have identified what is being 'damaged' in the process of cell division, and are working on drugs to prevent, and ultimately counteract that damage. In effect, to put us back at 'peak' age of ~24.
I'm 40 now, I wouldn't mind haven't my 24 year old body back...
This technology has interesting implications for space travel, as well as forcing a complete rethink of the 'pay as you go, borrow more tomorrow' philosophies of government. How different would you live you life knowing that once you saved enough money you wouldn't have to work again, and could have decades, or centuries, to more fully enjoy life?
Those interested in what an 'after-life' may hold will still be free to not take these drugs and proceed toward a natural death if that is their genuine preference.
After learning about the function of telomeres years ago I concluded that natural death is more than anything an evolutionary instrument to 'clear the stage' for the subsequent generation.
