If you happen to burn your hand, like when you accidentally place it in boiling water, don't run cold water over it - just dip it into a bag of flour for 10 minutes. It is said that in Vietnam, some people threw a bag of flour all over a guy who was on fire and that did not just put out the fire but the guy came out unscathed. He did not even have a blister. Keep a bag of flour in your fridge if you believe this piece of news that had been circulating round the Net! It pays to be prepared!
