The Gender Gap

This reasoning, however, does not explain why women live so much longer than men. "In all developed countries and most undeveloped ones, women outlive men, sometimes by a margin of 10 years," Perls and Fretts note. "In the U.S., average life expectancy at birth is about 79 years for women and about 72 years for men."

The gender gap is most pronounced in those who live 100 years or more. Among centenarians worldwide, women outnumber males nine to one. Perls and Fretts are studying all centenarians from eight cities and towns around Boston, 100 people in all. Eighty-five are women.

The mortality gap varies during other stages of life. Between ages 15 and 24 years, men are four to five times more likely to die than women. This time frame coincides with the onset of puberty and an increase in reckless and violent behavior in males. Researchers refer to it as a "testosterone storm." Most deaths in this male group come from motor vehicle accidents, followed by homicide, suicide, cancer, and drownings.

After age 24, the difference between male and female mortality narrows until late middle age. In the 55- to 64-year-old range, more men than women die, due mainly to heart disease, suicide, car accidents, and illnesses related to smoking and alcohol use. Heart disease kills five of every 1,000 men in this age group.
