Generational cohorts do not suggest generations, which are typically 20 to 25 years. Cohorts vary in the number of years covered. For marketing purposes, the relevance is in the years when the cohorts came of age.
The name Big Ben was given to a 13.7 tonnes, 2.2 meters tall, 2.9 meters wide hour bell, which is actually the main bell housed within the Clock Tower of the Palace of Westminâ¦ster. The tower, named Elizabeth Tower, is 96.3 metres (315.9 ft) high, 15 meters wide.
Big Ben was taken out of service and for the next three years the hours were struck on the largest of the quarter-bells. Eventually, a lighter hammer was fitted, a square piece of metal chipped out of the soundbow, and the bell given an eighth of a turn to present an undamaged section to the hammer.
