“We ... start out very small and we grow up? I’m older than Maitimo.”

"OK, but - we start small and then we grow up and then our bodies sort of slowly wear out, and we end up looking - like great-grandma, I don't know if Maitimo talked to her any. And eventually our bodies get too old and worn out to keep themselves alive anymore."

"That's awful."

"How, uh, old are you, exactly?"

"Maitimo was gone for about a third of a day. A year has twelve by twelve by ten days. I was born seventy years ago."

A hundred and forty four times ten is - about fourteen hundred divided by about three hundred and fifty, so about four years to one earth year, assuming the same day length which she really shouldn't assume. 

"I think that's older than we live to be. That... explains some things, honestly."

"What does it explain?"

"Well, you all know how to build houses and - stuff. And it seems like that might be a little easier to learn some of the stuff you know if you had a little more time to do it in."

"How long is it before people die of old age?"

"Somewhere between eighty and a hundred years, usually. Uh, ten by eight or ten by ten years. But our years are, like, three by ten by twelve days and I'm not sure what your day length is because I think Maitimo probably spent more time on Earth than he spent away from Valinor. I'm not certain."

"You slept for about a tenth of a day."

"Oh. OK. Your days are probably at least three times longer than ours."

"That is very little time to be alive."

"Well. We mostly don't bother learning to build our own houses."

"The Valar'll fix it, right?"

"I'm sure they will."

"How old is Maitimo?"

"Ten."

"Almost ten."

Twelve times WOW OK.

"You are... about five times older than I am. Apparently."

"Wow."

"I feel less bad about some stuff now, at least."

"I feel silly because I thought you were a grownup."

"I am! I just... grew up faster."
