If you were born in the United States in the year 1900 and you were a male, you could probably expect to live only to the age of 46. A female born at the same time could expect to live slightly longer until the age of 49.
But if you were born in the 1970s, you can expect to live to about 67.6 years if you are a male, and to about 75.3 years if you are a female.
