Aragorn was 87 in the movies, and he died at the age of 210 and Arwen died a year after him...so I estimate about for 120 years. Since Aragorn is a direct descendant of the Numenoreans, he has a long life-span.
And Arwen is supposedly supposed to resemble the fair elf Luthien who fell in love with a mortal man, Beren. and blah blah blah blah blah.
He ruled until 120 FA... which, as the Fourth Age doesnt start directly after the destruction of the Ring, means that he ruled about two years more than that 😉
And, yes, she is told to look like Lúthien Tinúviel the Nightingale who was the mother of Dior father of Elwing mother of Elrond father of Arwen 😉 which is quite near relationship in Middle-earth where practically all important people are related... even Boromir and Ingwe the High King of all Elves...
yeah it would get boring, i mean after youe seen everything and done everything
although elves are bound to the earth, they die when it dies, so some lucky elves will have gotten to see how the world ended, something to do with morgoth returning, and the sword that cleaved the world? im getting book of lost tales part one and two on saturday, so il read it up and tell, if fini allows 😛
