Trump will run for a third term, his nephew says

[Joe Cool]

7. Trump will have very noticeable physical deteroriation within two years

His body is going to give out soon. It´s hard to say when, but my guess is that at some point in the near future you will not see him walking around on camera. His staff will ensure that no cameras show him walking from Point A to Point B because he will look too feeble in the process, if he is even able to walk more than a few feet at a time.
Look at him walk around now. Very deliberate and he needs to focus on taking every step.
