i heard this on the radio there's a story that says a man 's skin turned blue coz he got silver poisoning.his blue skin is the result of a rare medical syndrome known as argyria but he thought it could make him younger. then the reporter asked the man,"How did you apply it to your face?" he answered,"Just cotton ball, swap it." and i look up the word "swap" in the dictionary,it means change, what does that mean???
