President Joe Biden is quoted by Politico as recently rhetorically asking allies: “You think I don’t know how f*cking old I am?" I’m sure he does know his calendar age, we all do.
The real question is whether his deteriorating condition permits him self awareness of how much ability and situational awareness he has lost. The answer is “probably not.” It tends to be the sort of thing we try to deny as we age.
Suffering from no blinders, the rest of us know and are embarrassed for him, and for our country.
