Memory.. minus the details

It occured to me, being older, that there are many things i “know” happened in life that i have no real memory of.

Seems this is genetic

Most of my older memories go something like this. Do i know what i learned in 4th or 5th grade? In short, I don’t remember a thing about it.  But i know i attended school those years.  My evidence of that is i know i graduated college, so attending prior schooling was a prerequisite.
