He's taking one for the team! He doesn't care if he's embarrassing himself even, because he has willingly elected himself to act as a tool for them in his last days. He recovered from his brain aneurysm surgeries years ago and the possible symptoms for any long term effects from those operations differ from what he is exhibiting now. There are also doctors on record as recently as 2019 saying he has recovered fully from those previous surgeries.
Maybe it's just Dementia but I have a feeling it is something much more sinister. Gliomas are the most frequent primary brain tumors in adults.
Memory Issues
Confusion or a decline in brain function
Mood Swings
Personality Changes or Irritability
Changes in Thinking
Speech Difficulties
Urinary incontinence
Drowsiness
This is just my speculation but it all sort of clicked when I read about "urinary incontinence" (in combination with the other symptoms)...it might be why Biden can't be seen in public for extended periods of time. Further down the rabbit hole, a brain cancer such as this could be induced through an ionizing energy weapon and perhaps McCain (and maybe Beau who was supposed to die as a child in the car crash that killed Biden's first wife and daughter) suffered the same demise.
Brain cancer? This is possible.
On the other hand, Biden has been yammering on stringing together absolute nonsense for years at this point. And, these symptoms can have a variety of root causes. Not to mention, everytime you type any list of symptoms into webMD or wherever cancer somehow manages to be a possible diagnosis.
Okay so, that's I guess possible? Extraordinary claims typically demand extraordinary evidence. That being said, welcome to the Q movement, we're totally into that kind of thing around here.
