Tibet is a historical region covering much of the Tibetan Plateau in Central Asia. It is the traditional homeland of the Tibetan people as well as some other ethnic groups such as Monpa, Qiang, and Lhoba peoples and is now also inhabited by considerable numbers of Han Chinese and Hui people. Tibet is the highest region on Earth, with an average elevation of 4,900 metres (16,000 ft). The highest elevation in Tibet is Mount Everest, Earth’s highest mountain, rising 8,848 m (29,029 ft) above sea level.
The Tibetan Empire emerged in the 7th century, but with the fall of the empire the region soon divided into a variety of territories. The bulk of western and central Tibet was often at least nominally unified under a series of Tibetan governments in Lhasa, Shigatse, or nearby locations; these governments were at various times under Mongol and Chinese overlordship. Thus Tibet remained a suzerainty of the Mongol and later Chinese rulers in Nanjing and Beijing, with reasonable autonomy given to the Tibetan leaders. The eastern regions of Kham and Amdo often maintained a more decentralized indigenous political structure, being divided among a number of small principalities and tribal groups, while also often falling more directly under Chinese rule after the Battle of Chamdo. Most of this area was eventually incorporated into the Chinese provinces of Sichuan and Qinghai. The current borders of Tibet were generally established in the 18th century.
A is an overland journey, usually a trip by tourists to Africa. In the past, the trip was often a big-game hunt, but today, safari often refers to trips to observe and photograph wildlife—or hiking and sightseeing, as well.
The Swahili word safari means journey, originally from the Arabic meaning a journey; the verb for «to travel» in Swahili is kusafiri. These words are used for any type of journey, e.g. by bus from Nairobi to Mombasa or by ferry from Dar es Salaam to Unguja. Safari entered the English language at the end of the 1850s thanks to Richard Francis Burton, the famous explorer.
The Regimental March of the King’s African Rifles was ‘Funga Safari’, literally ‘tie up the March’, or, in other words, pack up equipment ready to march.
In 1836 William Cornwallis Harris led an expedition purely to observe and record wildlife and landscapes by the expedition’s members. Harris established the safari style of journey, starting with a not too strenuous rising at first light, an energetic day walking, an afternoon rest then concluding with a formal dinner and telling stories in the evening over drinks and tobacco.
Road cycling is the most widespread form of cycling. It includes recreational, racing, and utility cycling. Road cyclists are generally expected to obey the same rules and laws as other vehicle drivers or riders and may also be vehicular cyclists.
Dedicated road bicycles have drop handlebars and multiple gears, although there are single and fixed gear varieties. Road bikes also use narrow, high-pressure tires to decrease rolling resistance, and tend to be somewhat lighter than other types of bicycle. The drop handlebars are often positioned lower than the saddle in order to put the rider in a more aerodynamic position. In an effort to become more aerodynamic, some riders have begun using aerobars. Who and when aerobars where invented is unclear but they seem to date back to the early 1980s. The light weight and aerodynamics of a road bike allows this type of bicycle to be the second most efficient self-powered means of transportation, behind only recumbent bicycles due to the latter’s higher aerodynamic efficiency.
