Why do we forget most of what we read and watch?

Not just what we read and watch. But also what we have written. And, if you were Johnny Carson, who you had just interviewed.

It’s an oddity peculiar to the live performer’s divided brain that needs exploring. It has to do with the fact that you — and the “you” that performs — are not identical.

I get the same thing all the time, whenever anyone asks me on a Monday morning what I did in the weekend.

Perhaps me and the “me” that was in the weekend are not identical. Certainly, my brain is in a totally different place — one that has difficulty piecing together an eventful yesterday.
