Don't forget Astarion's age was changed, 350 to 263.
Idle champions of the forgotten realms says Astarion is 263 years old he's an elf, though he looks 39.
SH is 40 years old and she looks younger, and she's a half elf who's aging faster.
There is no way he was a Magistrate at 39 and looked that way for his elven years. The dates on the gravestone (born 1229 DR) aren't correct.
He looks a very nice 39.
But a high elf at 39 should look very young, like 17-18 years old, given the lifespan of elves. Here for 350 (roughly 30-something for a human) it fits. In terms of D&D rules for the elven race, of course, this is wrong.
