A side comment was made by a news reporter asking why does Biden suddenly start yelling during a speech. I was reminded that people I knew with Alzheimers also suddenly became aggressive, yelling, fighting off health care workers etc. So with a little research I found this: https://www.alz.org/help-support/caregiving/stages-behaviors/agression-anger. Seems to show that his dementia (which we always knew) has progressed much esp in crowds of unfamiliar faces, getting lost, etc.

And this guy 'runs' the free world?
