A farmer in the United States raised a large herd of sheep, but from time to time he was taken away by nearby wolves. Over time, the loss of the farm became more and more serious. On this day, a zoologist moved near the farm. The farmer heard about it and quickly came to his door with a gift for help: "Please, help me, don't let the wolf eat my sheep again!"
"No, you should let the wolf eat the sheep." The zoologist said seriously, "but you have to feed it a'terrible' sheep." The farmer seemed to understand, so the zoologist gave him some Pills, and then told me. The farmer did so, first stuffing the pills into a dozen pieces of lamb, and then waiting for the opportunity to throw the meat into the wolves. The wolves crowded around and robbed them, and had a good meal. Soon, the lamb with "raw" made the wolves vomit.
A few days later, under the instructions of the zoologist, the farmer threw ordinary lamb into the wolves, but the wolves just got in and took a bite and walked away. After a few months, these wolves began to reject their favorite lamb, and even ignored the group of live little sheep in front of them. The farmer was pleasantly surprised, and thanked the zoologist again and again, saying: "You are really a god! I only know that sheep are afraid of wolves, but I never expected to see wolves and fear of sheep with my own eyes!" The
zoologist said: "Humans will like familiar ones. Delicious and willing to try new and novel foods. However, once they eat something that makes them uncomfortable, the next time they see this kind of food, they will have a very strong sense of rejection. Like humans, wolves will change after a setback. Be timid. Therefore, the best way to protect the sheep from attack is not to block the wolves blindly, but to send them an unpleasant meal, an uncomfortable experience.”
