My Little Pony XVIII: Perfect Isn't Easy

[WJMill]

Something I thought of recently (perhaps it has been addressed before):

If Celestia is Luna's older sister, and Luna was trapped in the moon for a thousand years, wouldn't that make Granny Smith REALLY REALLY ancient? Maybe it's an alicorn thing, but it seems kind of weird to me. If the aging process of ponies were the same for all races, Granny Smith would have to be at least two or two and a half thousand years old, and known about the times when the sun and the moon either didn't exist, or moved on their own? They don't really explain it in the show (obviously), but it leads to some interesting speculation.. Would ponies in late adulthood look as tall as Celestia? Even Luna looks a bit taller/lankier than the average pony..

Anyway, it's late and my head is muddled.

(Edit: I've been reading through The Old Stories, and I quite like it so far! I might post some critique for you, Thanqol. I'm only about halfway through it at the moment..)
