Boot Hill, or Boothill, is the generic name of many cemeteries, chiefly in the Western United States. During the 19th and early 20th century it was a common name for the burial grounds for paupers.
High heels spread from equestrian origins with the 10th century Persian galesh to wider fashion use. In early 17th-century Europe, high heels were a sign of masculinity and high social status.
