In March 2006, a law was introduced to forbid smoking in all enclosed public places in Scotland. Wales followed suit in April 2007, with England introducing the ban in July 2007. Pub landlords had raised concerns prior to the implementation of the law that a smoking ban would have a negative impact on sales. After two years, the impact of the ban was mixed; some pubs suffered declining sales, while others developed their food sales. The Wetherspoon pub chain reported in June 2009 that profits were at the top end of expectations; however, Scottish & Newcastle's takeover by Carlsberg and Heineken was reported in January 2008 as partly the result of its weakness following falling sales due to the ban. Similar bans are applied in Australian pubs with smoking only allowed in designated areas.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What was the month and year when England banned public smoking?
Ah, so.. July 2007

Garzê Tibetan Autonomous Prefecture and Ngawa Tibetan and Qiang Autonomous Prefecture in western Sichuan are populated by Tibetans and Qiang people. Tibetans speak the Khams and Amdo Tibetan, which are Tibetic languages, as well as various Qiangic languages. The Qiang speak Qiangic languages and often Tibetic languages as well. The Yi people of Liangshan Yi Autonomous Prefecture in southern Sichuan speak the Nuosu language, which is one of the Lolo-Burmese languages; Yi is written using the Yi script, a syllabary standardized in 1974. The Southwest University for Nationalities has one of China's most prominent Tibetology departments, and the Southwest Minorities Publishing House prints literature in minority languages. In the minority inhabited regions of Sichuan, there is bi-lingual signage and public school instruction in non-Mandarin minority languages.

In October 1810, six months after Fryderyk's birth, the family moved to Warsaw, where his father acquired a post teaching French at the Warsaw Lyceum, then housed in the Saxon Palace. Fryderyk lived with his family in the Palace grounds. The father played the flute and violin; the mother played the piano and gave lessons to boys in the boarding house that the Chopins kept. Chopin was of slight build, and even in early childhood was prone to illnesses.
