Why do men die earlier than women The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
"We have found that the power of .the male heart falls by 20--25 percent between 18 and 70 years of age," said the head of the study, I)avid Goldspink of Liverpool John Moores University in the UK.
"Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one third of those cells die and are not replaced in men," said Goldspink. "This is part of the ageing process."
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a
A. women have more cells than men when they are born
B. women can replace the cells that enable the heart to beat
C. the female heart loses few of the cells with age
D. women never lose their pumping power with age
