I might be completely wrong, but watching a documentary about time, the Einstein theory of relativity came up. From their explanation, time "slows down" depending where you are in the universe.
I have nothing against that, but I have heard many times that you can live longer if time slows down (this might not be a scientific sentence though, just heard it around and in movies). Now, if time is perceived differently from an observer's point of view, it is still the same time for you ( person inhabiting that part of the universe).
In this scenario, does the damage your body accumulate (which leads to death), slow down too? Would cells die slower and the whole cycle take longer to complete?
