"Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70l，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 20-year-old one's.

　　"This gender difference might just explain why women live longer than men,”said Goldspink.

　　They studied more than 250 healthy men and women between the ages of 18 and 80，focusing on healthy persons to remove the confusing influence of disease.

　　The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.

　　The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.
