How Do Elves Affect Humans

Elves develop very similarly to Humans for the first two decades, with both races reaching adulthood near the end of this time frame. Once this point is reached, physical advancement for an Elf slows down so much that it seems as if they aren 't aging at all. Elves are also not burdened by the curse of mortality that is present in all Humans, leading to the oldest Elves having an age upwards of eight centuries.
While they may be considered immortal by other races and even themselves, there have been cases of Elves dying of old age when they were older than 1000. Due to Elves still being affected by physical harm, such as disease, murder, and internal complications, it is highly unlikely for an Elf to live that long. As of the current date,

Both males and females Elves suffer from this curse, and so do all those descendents from Malin, which means halfbreeds will also suffer from this curse. This is the same to all sub-races of Elves, as they are all affected by it equally.
Elves age similarly to Humans in a physical sense until their twenties, making it possible for an Elf to have a child at this young age. This would, however, be highly unlikely because of both the curse and the Elven culture. An Elf would still be considered very young before the first half a century has passed of his life, and so not yet considered an adult responsible enough to raise a child. Elves would be taught to wait until adulthood before they have a child.
An Elven couple would have to pass many years together before finally being able to bare a child. When an Elven female is pregnant and gives birth, she will not be able to have another child for at least ten to fifteen years afterwards, but the norm for an Elf would be to wait much longer before having another child.
When reaching middle age at about 500 years old, an Elf will become fully infertile, never able to have a child again. This is true for both males and females of the Elven
