On Elven Ageing

Elves live approximately a thousand years, and the remarkable part is how little of that time they spend looking old. Human ageing proceeds with increasing accumulation of cellular damage, declining regenerative capacity, altered protein function, vascular stiffening, and a host of other processes which eventually become visible in nearly every tissue. Elves experience all of these things, but at greatly reduced rates and with unusually effective repair.

An Elf of six hundred may therefore appear, by Human standards, scarcely past middle age. Even at eight or nine centuries, many retain strength, mobility, skin elasticity, and cognitive sharpness which would be extraordinary in any Human elder.

This has led to the tiresome myth that Elves remain physically young until the last few years of life and then “suddenly age.” They do not. The illusion arises because their decline is compressed relative to their total lifespan. A Human may spend twenty years becoming visibly old; an Elf may spend a century doing the same thing, which sounds slow until one remembers that the preceding seven centuries were slower still. There is no abrupt transformation, merely a very long life eventually discovering that it is not infinite.
