We all know that everyone becomes a little more forgetful as they get older, but men's minds decline(衰退) more than women's, according to the results of a worldwide survey.
General differences seem to be inherent in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel (擅长) at recalling information from their brain's files. Many studies have looked for a connection between sex and the amount of mental decline people experience as they age, but the results have been mixed. Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline. Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, "so they're the ones that may not have shown such cognitive decline," said study team leader Elizabeth of the University of Warwick in England.
Scientists surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category (范畴) as possible in the given time, e.g. "object usually colored gray", and recalling the location of objects in a line drawing. The first two were tasks at which men usually excel; the latter are typically dominated by women. Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall.

B
At the middle school level, there are many academic clubs in which students can participate. Students can choose clubs that focus on an area of interest.
Mathcounts Club
Mathcounts tries to increase excitement towards mathematic achievement. It hopes to provide students with the foundation for success in science, technology, engineering and mathematics careers. Schools select individuals and teams to participate in competitions. Local competitions are held in February with winners progressing to state competitions and then on to the national level. Mathcounts works to challenge student math skills, develop self-confidence and give rewards for their achievements.
Envirothon
The Envirothon program focuses on natural resources knowledge and exposes students to diverse environmental issues, ecosystems, and topography. The ecology field competition for five-member middle school teams offers competitions in wildlife, soils, forestry, current environmental issues and aquatics. Students work and learn in middle school clubs and can compete at the local and state level.
Future Problem Solvers
Future Problem Solvers is an academic club that uses a six-step process to solve problems that may happen in the future. Students who are in the talented and gifted program, who like to “think out of the box,” or who enjoy thinking about futuristic problems may like this club. Teams comprised of four students read future scenes and write up solutions in a booklet using the six-step process. Teams that score high enough can go to the state competition and then to the international competition.
Builders Club
Builders Club is open to any middle school student who wishes to perform community service. Each Builders Club is co-sponsored by a Kiwanis club and the middle school. The members learn by doing, and they learn organization, teamwork, and leadership. Builders Clubs can sponsor a "Teacher of the Year" program, provide a recycling collection point, organize canned food and clothing drives to support local shelters, adopt a resident at a local senior citizens home, adopt a highway, tutor, etc.
Middle school academic clubs offer students a place to explore interests or talents. The clubs they join in middle school can help guide choices in high school and beyond.
