Holy cow, do I identify with this article. Even more the comments under it.
“…highly gifted children have an awareness and understanding of mortality at a much younger age than might be expected (some suggest that you can use the age at which a child understands mortality as a crude tool to approximate intelligence). Imagine then, for a moment, what it must be like for a child young enough to lack any significant autonomy and who relies on their parents for literally everything to understand that their parents are going to die in a way similar to how an adult might, but with the emotions of a young child. This can be an example of the asynchronous development experienced by many gifted children.”
