Life Expectancy
In most parts of the world, women live, on average, longer than men; even so, the disparities vary between 9 years or more in countries such as Sweden and the United States to no difference or higher life expectancy for men in countries such as Zimbabwe and Uganda.
The number of elderly persons worldwide began to surge in the second half of the 20th century. Up to that time (and still true in underdeveloped countries), five or less percent of the population was over 65. Few lived longer than their 70s and people who attained advanced age (i.e. their 80s) were rare enough to be a novelty and were revered as wise sages. Accidents and disease claimed many people before they could attain old age, and because health problems in those over 65 meant a quick death in most cases. If a person lived to an advanced age, it was due to genetic factors and/or a relatively easy lifestyle, since diseases of old age could not be treated before the 20th century.

Famous quotes containing the words life and/or expectancy:
“I was not born to be forced. I will breathe after my own fashion. Let us see who is the strongest. What force has a multitude? They can only force me who obey a higher law than I.... I do not hear of men being forced to live this way or that by masses of men. What sort of life were that to live?”
—Henry David Thoreau (1817–1862)
“If I had my life over again I should form the habit of nightly composing myself to thoughts of death. I would practise, as it were, the remembrance of death. There is no other practice which so intensifies life. Death, when it approaches, ought not to take one by surprise. It should be part of the full expectancy of life. Without an ever- present sense of death life is insipid. You might as well live on the whites of eggs.”
—Muriel Spark (b. 1918)
