I have this developing theory that intelligence is related to creating early memories.
My earliest memory was a sensation. In thinking and feeling the sensation now, I think my diaper was being changed and the sensation of the baby wipe going between my butt cheeks and legs was very unpleasant. I was in a dark room and there was a short wall to the right of me.
I have many other early memories - but I am trying to find out why, and what the commonalities are between myself and other early memory bearers.
