My dad swore fluoride was government poison for 20 years, then his dentist in Dayton showed him the X-rays
He finally got it, but it took watching his own teeth crumble while his brother who drank the tap water kept all his at 68, and now I wonder what else I wrote off just because he was loud about it.
My uncle spent 15 years refusing to wear a seatbelt because he knew a guy who knew a guy who got trapped by one. Meanwhile my aunt flew through a windshield at 40 and walked away with a scar and a new religion. The loudest guy in the room is usually just the most confident, not the most right.
