Don't be part of a flock of sheep. All sheep turn to dust. There is a novel created in the 16th century!! "Gargantua and Pantagruel" by Francois Rabelais. In one part of this novel, one of the characters argues with a wealthy merchant. Who is transporting a flock of sheep. So this character buys the bellwether from this wealthy merchant. After that he throws the bellwether overboard into the sea, and the whole flock of sheep starts to jump into the water one after another. This is an interesting example of such croud behavior which has been discussed since ancient times.
