Why do men die earlier than women? The latest research makes it known that the reason could be that mens hearts go into rapid decline when they reach middle age.
The largest study of the effects of ageing on the heart has found that womens 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 womans heart could perform almost as well as a 20-year-old ones.
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.

Wugging, or web use giving, describes the act of giving to charity at no cost to the user. By using Everyclick***, which is being added to a number of university computers across the UK, students can raise money every time they search, but it wont cost them a penny.
Research shows that students are extremely passionate about supporting charity 88% of full time students have used the Internet to give to charity. This age group is often the least likely to have their own income. 19% of 22 to 24 year olds have short-term debts of more than ￡5,000. With rising personal debt levels in this age group, due to university tuition fees or personal loans and a lack of long-term savings, traditional methods of donating to charity are often not appealing (有感染力的) or possible.
Beth Truman, a 21 year old recent university graduate, has used Everyclick*** to donate to her chosen charity, the RSPCA, for two years and has seen the wugging movement grow in popularity with students. When youre at university you become more socially aware, but its sometimes hard to give to others when you have little money yourself, says Beth. Wugging is great for people in this age group as it allows them to use the technology on a daily basis to give to charity, without costing them a single penny.
Wugging is perfect for people who want to be more socially aware and supportive but dont feel they have the means to do so. Students using the web can raise money for causes they care about without costing them anything in terms of time or money, and charities get a valuable source of funding.
Everyclick*** works like any other search engine, allowing users to search for information, news and images but users can decide which of the UKs 170,000 charities they would like to support through their clicks. Everyclick*** then makes monthly payments to every registered charity. Launched in June 2005, Everyclick*** is now the eighth largest search engine and one of the busiest charity websites in the UK.
6. According to the passage, wugging is actually ______.

D. a student movement
7. In the case of charity, Everyclick*** ______.

A. It makes Everyclick*** popular in the UK.
B. It becomes easy to do charity because of it.
C. It results in students more social awareness.
D. It helps students to save money.

A. most full time students do charity on the Internet every day
