Humans

 British judges wear white " wigs " (masks)  to give the impression of advanced age and wisdom. German judges dress up in violently scarlet garb to induce fear. It is the same as ancient warriors, such as Hercules, who wore lion skins and faces. The suggestion works on the wearer and the observer; it definitely works as the habit has survived for so long. No other animal is known to follow this habit. People can believe that they are animals or different persons. Isn't that bizarre?
