During a survival situation, you will have to make snap judgment about people. Are they telling the truth or are they lying? The answer to that question will let you know if you should trust the person or not. Here is a tip when you have to figure out if you can trust someone. Look at the person’s feet.
People have trained their faces to look honest when lying. However, their feet often betray them. Someone who is lying will often point his feet away from the person he is lying to, while someone who is telling the truth keeps his feet pointed directly at the person. This trick is so helpful that custom agents use it to find drug smugglers.
If someone’s feet tells you they are lying, don’t partner up with them or do any kind of business with them. A liar can get you killed during an emergency situation.
