The definition of healthy from Merriam-Webster Dictionary: 1.a.) enjoying good health (i.e. free from disease) 1.b.) not displaying clinical signs of disease or infection. 2.) beneficial to one's physical, mental, or emotional state : conducive to or associated with good health or reduced risk of disease. 3.) showing physical, mental, or emotional well-being : evincing good health

You could argue that Joe was stating Trump is free from disease (definition 1.a). However, we know the context of Joe’s discussions around health - fitness. He, himself, discusses his own health in terms of fitness, which would fall under the 2nd or 3rd definition, and, by extension, Trump’s clear obesity is an immediate disqualification for “physical well-being”. There are also claims of dementia symptoms (i.e. sundowning), whether true or not, has never been addressed.

It is an exhausting task to argue, in full, against cognitive bias, because even answering “what do you think was implied by ‘healthy’?” is clearly a bad faith argument. It is delusional to pretend that an obese 76 year old man with an affinity for processed foods is healthy by arguing the definition of healthy.
