If you want to stay young, sit down and have a good think. This is the _1_finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise and as a result, we are ageing unnecessarily soon.

Professor Taiju Matsuzawa wanted to find out why otherwise _2_farmers in northern Japan appeared to be losing their ability to think and reason at a _3_early age, and how the process of ageing could be _4_down.

With a team of colleagues at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages and varying occupations.

In a classroom at American University in Washington D.C., the benefits and _2_of the new wireless work were on display. From the back row of a lecture hall, more than a dozen laptop screens were visible.

A young man shows an _3_email to the woman next to him, and then switched over to read the online edition of The Wall Street Journal. Distraction is nothing new. As long as there have been _4_, students have whispered, passed notes and even gazed out the window and daydreamed. But the arrival of the laptop has introduced new _5_for distraction, and wireless introduces an even _6_range of distraction.

This is _7_annoying for law professors, many of whom still live in the world of paper. “This is something that hurts the students themselves,” said Ian Ayres, Professor at Yale Law School, who _8_the internet’s entry into the classroom. However, Professor Mallek sees it differently. He said the benefits of the technology _9_the problems. He suggested that it might even be making him a better teacher.

But the Americans are in a _3_. The problem is the way in which health care is _4_and financed. Contrary to public belief it is not only a free competition system. To the private system has been joined a large public system, because private care was simply not looking after the less _5_and the elderly.

But even with this huge public part of the system, which this year will eat up 84.5 billion dollars, large

numbers of Americans are left out. These include about half the 11 million unemployed and those who _6_to meet the strict limits on income fixed by the government.

The basic problem is that there is no central _7_over the health system. There is no limit to what doctors and hospitals _8_for their services. The number of doctors has shot up and prices have _9_. When caught ill, all the unfortunate person _10_can do is pay up. It is no surprise that the rising cost of medicine in U.S.A. is among the most worrying problems.
