As Hillary "said," I can't remember my brain my brain's in a blender, it's jello!
On special occasions, he can remember back a century or more. As he noted recently:
"We cannot let this, we’ve never allowed any crisis from the Civil War straight through to the pandemic of 17, all the way around, 16, we have never, never let our democracy sakes second fiddle, way they, we can both have a democracy and elections and, at the same time, correct the public health.”
I'm sure ol' Joe loves to reminisce, about anything that comes to mind (real or imaginary). 'When I was a whippersnapper, about the time those dog-faced pony soldiers rustled our entire herd of chinchillas, but maybe a year or so before Amelia Earhart and Sir Edmund Hillary stole my mother's favorite Victrola, I remember...'

It doesn’t matter what he doesn’t remember. The convicting evidence will come from the testimony of others saving their own hides
