I think there is some validity here. He has a short fuse. I’d say he’s suffering from depression.
He isn’t chasing skirts IMO after seeing him up close twice this year he does not have the flirt charisma.
He is over tired. Heard he is supposed to use O2 at night and wont.
His Doc who travels with has a defib machine near by at all times and O2.
So my guess is he is not pacing himself and going full board sun up to late night ignoring any signs of fatigue or need for rest time.
Any real medical doc here at FR could probably spout off what they see by looking at his face health wise.
When my dad had open heart surgery we were told by the doctors that IT WOULD change his mental state.
