musings on dnd style elves:

why do I never see elves that age the same as humans, but slower. e.g. being a baby for like 20 years, a child for like 40 years, etc.
why are elves always marginally shorter than humans, I feel like only the very tall elves and very short humans should overlap in height.
I want to see more spidery stuff incorporated into elves as a whole. drow can have house spiders and all the cave guys, but surface elves should revere jumping spiders and other surface arachnids

When elves finally die they get a big burst of every thing they would have dreamed about could they sleep
sea elves are just dumb
do elves have arboreal adaptations?
what is the advantage of long ears?
what does living a thousand years do to a being, especially with no sleep? the only animals that do that are too dumb to know or are a shark
why is there a bunch of 500 year old elves going on adventures at level 1? surely they would build skill up
maybe elves have slight fey tendencies, like as annoying as hiccups. urge to ask to come in, people around them forget their own name briefly when asked, favors are more important to them than to other humans
