You either have a sense of direction,or you don’t.But why is it that some people could find Their way across the Sahara without a map,while others can lose themselves in the next street?
Scientists say we’re all born with a sense of direction,but it is not properly understood how it works.One theory is that people with a good sense of direction have simply worked harder at developing it.Research being carried out at Liverpool University supports this idea and suggests that if we don’t use it,we lose it.
“Children as young as seven have the ability to find their way around.”says Jim Martland,Research Director of the project.“However,if they are not allowed out alone or are taken everywhere by car,they never develop the skills”
Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction.He makes the following suggestions:
●If you are using a map.turn it so it relates to the way you are facing.
●If you leave your bike in a strange place.put it near something like a big stone or a tree.
Note landmarks on the route as you go away from your bike.When you return,go back along the same route.
●Simplify the way of finding your direction by using lines such as streets in a town,streams,or walls in the countryside to guide you.Count your steps so that you know how far you have gone and note any landmarks such as tower blocks or hills which Call help to find out where you are.Now you will never get lost again !

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(下降) 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, David 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 20-year-old one’s. “This gender( 性别) 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.
