The average lifespan of people varies from country to country. If you live in a developed country, then you can expect to live longer. For example, Australians live, on average, 76 years, West Germans and North Americans 75 years and Britains 74 years.
In poorly developed countries, where many people do not have enough to eat, suffer many diseases and lack good health services, lifespans are much shorter. Examples include Ethiopia, 43 years; Nepal, 46 years, and India, 55 years.
Women usually live longer than men. For instance, the average life expectancy at birth for women in the USA is 79 years-seven years more than men.
