expectation of life

Among older people, particularly those aged over 75, the higher number of females reflects the longer expectation of life for women, partly as a result of higher rates of male mortality during the Second World War.

As a rule, however, we may conclude that the expectation of life was very short.

The expectation of life at the age of 60 of the ancients were nearly 15 years, of the modern musicians 13½.

On the other hand, the expectation of life of those who had attained their 80th year, was in these four centuries respectively 6.22, 5.87, 4.40 and 3.84 years.

If a Giant Tortoise is hale and hearty at five hundred, and a Yellow Leaf is trying to inveigle a Mere Bud towards the matrimonial altar at ninety-something, what is the reasonable expectation of life of an old Lady who has nothing to die for?
