OK, at the end of the First Age, the Peredhil or Half-Elven, are given an irrevocable choice of kindreds: To become forever one of the Firstborn, the Elves, or to become one of the Followers, ie: Men.
The Elves are bound to Arda, the world, and will live as long as Arda exists. Their bodies may die, but their spirits then go to the Halls of Mandos to wait until the End. Barring accident, death in battle, or death from world-weariness (in a few cases), they are effectively immortal. In addition, they are strong, beautiful, wise, cultured, and in all respects superior to Men.
Men are mortal. They will die at the end of their lifespan (which in the First Age was quite long by our standard, although not by that of the Elves) and their spirits, not being tethered to Arda, go somewhere else, and not even the Valar, the Gods, know where that is or what fate awaits them, although it is thought that at the End of Days they will return to join with the Firstborn, the Valar, the Miar, and the Ainur in making the Great Music with Ilúvatar.
The Peredhil, Elrond and Elros, were given the choice. Elrond chose to become one of the Eldar, and a master of lore and wisdom. Elros chose to become one of the Edain, and became King of Numenor and father of all the Kings of the West, including, ultimately, Aragorn Telcontar.
Right. So with that all out of the way: You are given the choice of kindreds. Which do you choose?
In my youth, this was a no-brainer. The Elves are strong, wise, live forever and are in every way cooler than cool.
Now, at fifty-plus, I lean the other way. Immortality sounds great at first, but, having experienced a significant chunk of eternity, I can see that it would become an enormous burden, one I am not willing to assume. So, I choose the choice of Elros, to be a Man, and, ultimately, to die and quest beyond to wherever Man’s spirits go.
How about you?
