So, you’re in Brazil and before you realize the Portuguese word for “hot!” is ardente! you’re on the way to a Rio hospital with second-degree burns. Then, before you can scream “Send me back to America!” a team of doctors rushes in with moist pieces of fish skin … and slap them on your wounds. Making seemingly primitive matters worse, the skin isn’t even from some cool Brazilian fish, like a peacock bass or a red-bellied piranha. They’ve slapped you with the coverings of farm-bred tilapia. How aboriginal!

But fear not, you haven’t flown over 2,000 miles for a dream vacation in Ipanema only to die of some exotic form of fish-skin…
