SicSemperTyrannis: It's not that Trump doesn't understand his health experts. Trump discounts EVERYONE who doesn't tell him EXACTLY what he wants to hear and who doesn't flatter his fragile over-inflated ego. NOBODY has ever told him he's wrong so he's gone through his entire life believing that the world yields to his will alone. When he's faced with adversity he claims that he's a victim and that there's an giant conspiracy against him and his genius plans. Anyone who didn't see this coming has been in basic denial of his character for a very long time.
