everyone knows what he looks like though. that would be hard to get away with doing..
but even if it was on his tongue, that doesn't mean his asthma and prostate isn't taken care of/cured/fixed. it just means he has oral thrush or candida on his tongue.
eta: hypothetically...
i really have no idea what his tongue looks like.
i still can't wrap my head around why someone would make that up.
especially since he takes more shit from people than he has people worshiping him for his info.. so it can't be an ego thing.
If you really want to prove him wrong about iodine, why don't you just take it and see for yourself?
