My whole life random people been like "what do you weigh like 220" and I've been like no I weigh X (It's varied) and I couldn't figure out why people never could get near my weight then I realize, it's because like everyone lies about their weight unless they're forced to step on a scale for something like a weigh in for sports.
Trump isn't 6'3 either, there's multiple pictures of him next to Brady who's 6'4 by NFL measurements and Brady towers over him by a minimum of 2 inches. There's a photo of him next to A-Rod, A-Rod has a slight lean and his eyes are at Trump's forehead and A-Rod has a much longer forehead than Trump as well and he's listed at 6'3.
Like why lie about your height that much? What does it gain than make you look insecure?
