if 100 is the age of adulthood then it is equivalent to 18 in human years

I get the 21 , but I'm not clear about the 100.

only if you assume the drinking age is 21 or the equivalent. An assumption that is true for a small percentage of population of the world for a small fraction of human history

Nah, it checks out. I ran the numbers myself and I got 15.33, which is roughly 15. This, of course, assumes the age of adulthood is 21 for humans and 100 for elves, and we don't really have a reason to doubt those numbers.

Others have doubted the 21 year figure being appropriate for humans but I think the 100 year figure is ridiculous for elves. It’s based on the assumption that age of maturity and total lifespan are always preserved in an exact ratio across different species, when this is demonstrably not the case.

I own that top in black.

Does it matter? If we used maturity as a measure, I would still be unable to drink.

I’m talking about physical maturity, not emotional maturity (which is greatly influenced by environment).

You are such a medieval wench though.

In D&D, the standard assumption is that elves mature just as fast as humans, but they are culturally treated as children until around hundred or just a bit higher. But I’ve started developing a campaign setting where elves really are the equivalent of kids until that age, and all the implications of that. One of which is that, if humans attended school alongside elven kids, they’re going to lose their reputation of mystique and wisdom— they’re going to be viewed as kinda slow and dimwitted, as the humans graduate through the grades and the elevens get held back a decade or so.
