Hi

From this http://fi.edu/guide/sowd/teachbacklifespan.html it says :

There are "two kinds of life span. One is maximum life span, the greatest age reached by any member of a species. In humans this is 120 years, we think. The other is average life span, the average age reached by members of a population. Life expectancy, the number of years an individual can expect to live, is based on average life spans.

So is my understanding correct that I think Life expectancy = average life spans

Please give me example (statistic example) of Life expectancy or average life spans in sentences to see the differences of life expectancy and life span so I will use these 2 phrase well.

Thanks
