If we evolve at all, we are transient by nature and cannot live in a transient state forever by definition. Never mind, from ScienceDaily:
As Charles Darwin explained, natural selection results in the fittest individuals for a given environment surviving to breed and pass on their genes to the next generation. The more fruitful a trait is at promoting reproductive success, the stronger the selection for that trait will be. In theory, this should give rise to individuals with traits which prevent ageing as their genes could be passed on nearly continuously. Thus, despite the obvious facts to the contrary, from the point of evolution ageing should never have happened. This evolutionary contradiction has been debated and theorised on since the 1800s. It was only in 1953 with his hypothesis of antagonistic pleiotropy (AP) that George C. Williams gave us a rational explanation for how ageing can arise in a population through evolution. Williams proposed that natural selection enriches genes promoting reproductive success but consequently ignores their negative effects on longevity. Importantly, this is only true when those negative effects occur after the onset of reproduction. Essentially, if a gene mutation results in more offspring but shortens life that’s fine. This is because there can be more descendants carrying on the parent’s genes in a shorter time to compensate. Accordingly, over time, these pro-fitness, pro-ageing mutations are actively selected for and the ageing process becomes hard-wired into our DNA. While this theory has been proven mathematically and its implications demonstrated in the real world, actual evidence for genes behaving in such as fashion has been lacking.
This evidence has now arrived according to the co-lead author of the paper Jonathan Byrne, “The evolutionary theory of ageing just explains everything so nicely but it lacked real evidence that it was happening in nature.
So it was believed without evidence because Darwinism “explained” it?
Evolution becomes blind to the effects of mutations that promote ageing as long as those effects only kick in after reproduction has started. Really, ageing is an evolutionary oversight.” Jonathan continues “These AP genes haven’t been found before because it’s incredibly difficult to work with already old animals, we were the first to figure out how to do this on a large scale.” He explains further “From a relatively small screen, we found a surprisingly large number of genes  that seem to operate in an antagonistic fashion.” Previous studies had found genes that encourage ageing while still being essential for development, but these 30 genes represent some of the first found promoting ageing specifically only in old worms. “Considering we tested only 0.05% of all the genes in a worm this suggests there could be many more of these genes out there to find,” says Jonathan.

Everything in our frame of reality is transitory by nature and it would not have been possible to evolve a means to prevent aging. All that really happened is, things became less efficient as they aged. The Darwinism is superfluous but culturally comforting to some.
