Signs point to yes. One of the first things your Ghost tells you once you reach the Tower is that The City took centuries to build. There's plenty of other references to similarly long periods of time having passed since the collapse. It seems pretty clear that some Guardians have lived for hundreds of years since being found by their Ghosts, but do they age, die and get brought back to life again and again, or are Guardians frozen at the age they were when their Ghosts first revived them?

I was unsure before, but now I assume that we are frozen at our age, mostly because of the latest Rise of Iron trailer with Saladin. For being REALLY old, he looks fairly young.
