The age-old riddle of why many women
live longer than men has been solved. It’s their pumping power, British
researchers have found. On average, women live five years longer
than men and women over the age of 60 are now the fastest-growing section of the
British population. The average male heart becomes weaker with age, and by the
age of 70 its power to pump blood around the body could have decreased by up to
a quarter of its youthful strength. David Goldspink, Professor
of Cell and Molecular Sports Science at Liverpool John Moores University, said
yesterday that women’s longevity is linked to the strength of their hearts.
Unlike men, they pump just as strongly at 70 as they do at 20.
"We have found that the power of the male heart falls by 20 -25 percent
between 18 and 70 years of age," Professor Goldspink said. "In stark contra A. Because women’s pumping power is better. B. Because women live five years longer than men. C. Because male’s heart is weaker than female’s. D. Because the power of women ’ s hearts decrease.
