According to a recent survey conducted by research scientists at the Montgomery university at Timbaktoo, it has been observed that the average age of people living in buildings without elevators is greater than of those living in buildings with one. Scientists observed a group of people living in the northern part of Timbaktoo city where the buildings are old, do not have elevators and people have a generally lower standard of living as compared to those living in the south, where sky-scrapers abound, and the standard of living is considerably higher. It was expected that the richer would live longer, since they eat healthier food, and can afford costlier medication. The results however were not in accordance with that theory.
As it turns out, the poorer people, with their low standard of living, and simple eating outlive the rich by an average age of 6~7 years. The northers sample space had an average life expectancy of 89 years whereas the southern sample space recorded a mere 82 years. It is believed that this singular occurrence if because of the fact that people living in the poorer parts of the city do not have elevators in their buildings and are forced too use the stairs, which is considered to be a good exercise for the heart and kidneys. Researchers have yet to conclusively nail this as one of the main reasons as to why people in the north live longer.
