Fluff-wise, I'd advise you switch it for the "doesn't get aging penalties" ability that monks and druids get. "Never dies of old age" has all sorts of fluff implications that you probably don't want (most notably that you're almost never going to change who the high priest of a religion is), whereas the "no aging penalties" approach actually has precedent (Deuteronomy 34:7)
