A desert is a hostile, potentially deadly environment for unprepared humans. In hot deserts, high temperatures cause rapid loss of water due to sweating, and the absence of water sources with which to replenish it can result in dehydration and death within a few days. In addition, unprotected humans are also at risk from heatstroke. Humans may also have to adapt to sandstorms in some deserts, not just in their adverse effects on respiratory systems and eyes, but also in their potentially harmful effects on equipment such as filters, vehicles and communication equipment. Sandstorms can last for hours, sometimes even days. Despite this, some cultures have made hot deserts 'their home for thousands of years, including the Bedouin, Tuareg tribe, and Pueblo people. Modern technology, including advanced irrigation systems, desalinization and air conditioning, has made deserts much more hospitable. In the United States and Israel for example, desert farming has found extensive use. In cold deserts, hypothermia and frostbite are the chief hazards, as well as dehydration in the absence of a source of heat to melt ice for drinking. Falling through pack-ice or surface ice layers into freezing water is a particular danger requiring emergency action to prevent rapid hypothermia. Starvation is also a hazard; in low temperatures the body requires much more food energy to maintain body heat and to move. As with hot deserts, some people such as the Inuit have adapted to the harsh conditions of cold deserts.

Rock Band

Two years ago, our 14-year-old son, Ben, asked us for a set of drums for his birthday. At first, we were very much against the idea because of the noise. 'It's better than watching television or playing computer games in my free time,' Ben argued, 'and it'll keep me out of trouble.' In the end we gave in. 'All right,' we said, 'but you must consider the rest of the family and the neighbours when youplay.' That was just the beginning. Because drums are not the easiest instruments to transport, the other members of Ben's band started appearing at out home with their guitars and other electrical instruments. And so, for several hours a week, the house shakes to the noise of their instruments and their teenage singing. At least Ben's hobby has been good for our health: whenever the band start practising, my husband and I go out for a long walk. And I must admit that, although their music may sound a little strange, they are a friendly and polite group of young men. I cannot judge their musical skill - after all I didn't expect my parents' generation to like the same music as I did when I was a teenager - but they do play regularly in local clubs for young people. Our main worry is that they won't spend enough time on their school work because of their musical activities, though this hasn't happened yet. I am always stressing to Ben how important his studies are. But one thing is certain - Ben was right: it has kept him out of trouble and he is never bored.

Craigie Aitchision"

The painter Craighe Aitchison was born in Scotland. He came to London intending to study law, but went to art school instead. There he found the traditional drawing classes difficult, but still kept on painting. In his late twenties he was given money by the Italian government to study art, and became interested in early Italian artists, which show in some of his work. He loved the greens and browns of Italian fields and the clear light there, and wanted to put this light into his paintings. This led him to paint colours thinly one on top of another from light to dark, but he insists he's never sure the results will be. He says, 'It's a secret - because I don't know myself. I don't start by painting yellow, knowing I'm going to put anything on top. ' Like most talented people, Aitchision makes it sound easy. ' Anyone can do the colours - you can buy them. I simply notice what you put the colours next to.' Unlike some artists, he never does drawings before he starts a painting, as he feels that if he did, he might get bored and not do the painting afterwards. Instead, Aitchison changes his paintings many times before they are finished. This explains why his favourite models are people who don't ask to see their pictures while he's painting them. 'If I feel they're worried and want to look at the painting, I can't do it''. Since moving to London years ago, he has not felt part of the Scottish painting scene. He says he is not interested in following any tradition, but just paints the way he can. However, his work still influences young British painters. 

The young achiever of the year

Kal Kaur Rai has always been interested in fashion and has just won the title of Young Achiever of the year at the Asian Business Awards. Ever since she was a child, she has drawn clothes and designed patterns. She never told her hard-working parents, who own a supermarket, that she wanted to turn her hobby into a career. She thought they expected her to go into a more established business, so she went to university to do a management degree. After university, she moved to London and worked in an advertising agency. She had to attend industry events but couldn't afford the designer clothes she liked. She started making skirts and tops for herself. When her friends saw her clothes, they asked her to make things for them. She then found a small shop in London willing to take her designs on a sale or return basis. They were very popular and nothing came back. This encouraged her to leave her advertising job , take out a £20,000 loan and begin her own women-wearlabel. Kal's parents were not angry about her career change and said they would support her, which really pleased her. Her clothes are now on sale in over 70 stores and her business has an income of over £500,000. Her clothes appear in fashion magazines, she designs for pop stars and she has just gained public recognition by winning this award. Her business has come a long way and she knows she is extremely lucky. 'What I do is my hobby - and I get paid for it! But remember, I've worked hard for this.' 

DO YOU DRINK TOO MUCH COFFEE?

How much coffee is too much? Most doctors say one cup a day is more than enough. However, most people who work in offices drink two or more cups a day. Many drink coffee during breaks, at lunch, and on their way to and from work. On the other hand, most people don’t drink enough water. This is especially a problem for coffee drinkers. When people drink coffee, they don’t drink water. Most doctors agree that everyone should drink at least eight glasses of water a day.
