I dunno.
I have those "holes" in my own learning, even at this age.
I credit that to deafness, although it might be a lack of cerebral cells in certain parts of the brain.

What's always been interesting for me is that physicians new to me, in their office notes, put down that I "show traces" of "autism," or have "residual autism," which blows my mind, considering that autism was already well-known when I was a little lad, and no physician at that time ever noticed it.
Maybe I had it, and no one noticed, and I grew out of it.
I dunno.
I suspect a lot of "psychological problems" are overdiagnosed and overtreated.
Children are imperfect beings; they naturally and instinctively, if given guidance, discipline, and illumation, grow out of those "problems."
