“Yes,” Forerunner said. “Pony species do not naturally age. Or… to be more precise, damage to their bodies does not become cumulative over time. I confirmed this with Dr. Born’s help, using observations of tissue samples obtained from the natives, and in my own experiments. This trait is not possessed by the animal specimens we obtained, or the plants. I am unsure if it applies to the non-pony sapient races on Sanctuary. Nevertheless, it appears that every pony citizen possesses latent biological immortality.”
