My mother says she doesn't remember 'anything', but she doesn't get angry or overly upset about it. I imagine it being like having thoughts at the tip of your tongue, repeatedly, and accepting it. She actually laughs at herself for forgetting or doing nutty things.
This article may sound pitiful, a grown man playing with infant toys, but he was HAPPY. The parts of his brain that functioned were 100% .
