I signed myself up as a TRIP US Founding Member as a birthday treat for myself (and they had an offer on). They did a special few episodes on Trump’s health and the consensus, between them and consulting with doctors, was that Trump doesn’t have anything specific wrong with him like dementia, but that he is in exactly the condition you would expect an 80 year old man with a poor diet to be in - needing more rest, forgetful on names, etc.
Mooch pointed out that he’s always been a pretty healthy individual and as a young man was a good athlete, which often sets you up for a long life.
On the regular cognitive tests they did agree that it was unusual to see so many happening (and also pointed out that it’s not the type of test where you can score 100%!) but that if you were trying to keep an eye on an 80 year old with access to the launch codes, you probably would want to test them regularly anyway.
I look at my dad, who is nearly 78 - he has a multitude of health conditions that mean he rarely leaves the house. He struggles to walk, gets out of breath easily and sleeps a lot of the time. In a lot of ways Trump is in better condition than many his own age.
