Evolution basically aids in reproduction, not living. Any mutation that keeps you alive but not reproducing isn't gonna have any more advantage than
anything else by natural selection.
Example; Sea horses dying right after mating.
Aging is caused by mutations in the skin. Our cells aren't subject to natural selection, because even the "weaker" ones aren't killed off, and are
still supported by the body.
We have evolved(ironically) methods of double checking information in our genes before passing it on. We've got the design to try to catch stop
mutations, it's just imperfect. Allow me to rephrase that: We've got the design to try to catch stop aging, it's just imperfect.
Also, hypothetically, a perfect system would actually be damaging. Without mutation, there'd never be good mutations to keep, and no species would be
able to further develop and adapt.
I'd pick aging over being completely unfit for my environment, and getting killed off because of it.
I'd recommend "The Selfish Gene" by Richard Dawkins. It would do a much better job answering your question than I could.
