Located on the South Head peninsula in eastern Sydney, Australia, the Gap is an ocean cliff that is known as a popular travel destination as well as a suicide spot. Numerous people have chosen it as the terminal station of their lives since 1800. However, the suicide rate has decreased precipitously since 2000 because of the efforts of Don Ritchie, who has been awarded the title "The Angel of the Gap." Whenever he saw a person walking toward the cliff, he would talk with them and invite them to have a cup of tea. He has saved 160 lives so far.
