This suggestion is totally simple and canonical.
As most people may know, Gondor's men are descendants of Numenor, and the men who came from this island tend to live longer lives than others, and now that the suggestion really begins.
I wish that to exemplify this in the mod all Gondor NPCs with the exception of a few (Swan Knight and Gondor Tower Guard) have 25 of life.
And to put it a little further, I wish the Gondor Tower Guards had this shield here (The player could also use it)
