In 1895, members of the Gloucestershire Engineer Volunteers reenacted their famous stand at Rorke's Drift, 18 years earlier. 25 British soldiers beat back the attack of 75 Zulus at the Grand Military Fete at the Cheltenham Winter Gardens. Veterans of the American Civil War recreated battles as a way to remember their fallen comrades and to teach others what the war was all about. The Great Reunion of 1913, celebrating the 50th anniversary of the Battle of Gettysburg, was attended by more than 50,000 Union and Confederate veterans, and included reenactments of elements of the battle, including Pickett's Charge. During the early twentieth century, historical reenactment became very popular in Russia with reenactments of the Siege of Sevastopol , the Battle of Borodino in St Petersburg and the Taking of Azov in Voronezh in 1918. In 1920, there was a reenactment of the 1917 Storming of the Winter Palace on the third anniversary of the event. This reenactment inspired the scenes in Sergei Eisenstein's film October: Ten Days That Shook the World. Large scale reenactments began to be regularly held at the Royal Tournament, Aldershot Tattoo in the 1920s and 30s. A spectacular recreation of the Siege of Namur, an important military engagement of the Nine Years' War, was staged in 1934 as part of 6-day long show. In America, modern reenacting is thought to have begun during the 1961-1965 Civil War Centennial commemorations. After more than 6,000 reenactors participated in a 125th anniversary event near the original Manassas battlefield, reenacting grew in popularity during the late 1980s and 1990s, and there are today over a hundred Civil War reenactments held each year throughout the country.

Of 3,143 counties in the United States in 2013, Fayette County ranked 2,882 in the longevity of male residents and 3,091 of female residents. Males in Fayette County lived an average of 71.2 years and females lived an average of 75.3 years compared to the national average for longevity of 76.5 for males and 81.2 for females. The average longevity of men in Fayette County increased by 2.0 years from 1985 to 2013 compared to a national average for the same period of an increased life span for men of 5.5 years. The average longevity, however, for females in Fayette County declined by 4.2 years between 1985 and 2013 compared to the national average for the same period of an increased life span of 3.1 years for women. High rates of smoking and obesity and a low rate of physical activity appear to be contributing factors to the low level of longevity for both sexes.

How many years did it take for the longevity of men in Fayette County to increase 2.0 years?
A: 28

A central feature of the white community in Rhodesia was its transience, as white settlers were just as likely to leave Rhodesia after a few years rather than permanently settle; for example, of the 700 British settlers who were the first white settlers, arriving in 1890, only 15 were still living in Rhodesia in 1924. As the white population of Rhodesia had a low birth rate (18 per 1,000 compared to the African rate of 48 per 1,000), to maintain white population growth was largely dependent upon taking in new white immigrants with immigration accounting for 60% of the growth of the white Rhodesian population between 195572. However, the American historian Josiah Brownell noted that the turnover rate for white residents in Rhodesia was very high, as Rhodesia took in a total of 255,692 white immigrants between 195579 while the same period a total of 246,583 whites emigrated. Even during the boom years of the late 1950s, when Rhodesia took in an average of 13,666 white immigrants per year, mostly from the United Kingdom and South Africa, an average of about 7,666 whites emigrated annually. Between 196165, Rhodesia took in an average of 8,225 white immigrants per year while also having an average white emigration of 12, 912 per year. Many prospective white immigrants in Rhodesia arrived seeking economic opportunities and departed with fluctuations in the security situation as the Bush War intensified. A substantial number were uninterested in settling there permanently and did not apply for Rhodesian citizenship, despite a much-publicised 1967 campaign urging them to do so. Brownell asserted that patriotism in the white community was "shallow" due to its essentially expatriate character. Brownell also claimed that the majority of white immigrants in the late 1960s and early 1970s were unskilled laborers who competed with the countrys black African workforce and did not contribute badly needed technical or professional skills to the country. He argued that this was due to a government policy aimed at making white immigration as "unselective as possible" and guaranteeing every white immigrant a job.
