A geisha is a traditional Japanese artist-entertainer skilled at conversation, singing, and dancing. The geisha system likely originated in the 17th century to provide a class of well-trained entertainers separate from courtesans and prostitutes. Even though geisha are usually women, the first ones were actually men. The numbers of geisha have declined from some 80,000 in the 1920s to a few thousand today. Why did geisha often paint their teeth black as part of their formal make-up? Discuss
