Yet now he met Erendis often (and that was by contrivance of the Queen); and the King learning of their meetings felt disquiet, yet he was not displeased. "It would be more kind to cure Aldarion of his restlessness," said he, "before he win the heart of any woman." "How else will you cure him, if not by love?" said the Queen. "Erendis is yet young," said Meneldur. But Almarian answered: "The kin of Erendis have not the length of life1 that is granted to the descendants of Elros; and her heart is already won."
Unfinished Tales, Part 2, Ch 2, Aldarion and Erendis
There are several references to the greater life-span of the descendants of Elros than that of any others among the Númenóreans, in addition to those in the tale of Aldarion and Erendis. Thus in Akallabêth [...] it is said that all the line of Elros "had long life even according to the measure of the Númenóreans"; and in an isolated note the difference in longevity is given a precise range: the "end of vigour" for the descendants of Elros came (before the waning of their life-span set in) about the four hundredth year, or somewhat earlier, whereas for those not of that line it came towards the two hundredth year, or somewhat later.
