More than meets the eye in colours
Fashion dictates not only the clothes we wear, but the colours, too.
If you take a stroll around the fashion department of any store today, you will be dazzled by the variety of colours available.
In ancient civilisations, every colour had a meaning. For example, yellow was the symbol of the sun and of ripe corn growing in the field. Red stood for blood.
What's more, ancient people used colours to distinguish themselves as belonging to different tribes, while men and women used colours for different purposes. For instance, women used colours and patterns to emphasise their body shape while men used them to emphasise their strength and skills.
Today colour is mostly about fashion and style.
Every colour under the sun is available in today's style parade.
Bear in mind, though, that we all have colours that suit us best. Don't blindly follow trends. Wear what suits you. Find out what your most flattering colour is.

The pros and cons of using Facebook
My two brothers are addicted to the online social networking website called Facebook. I joined about six months ago, but in recent weeks I have given up updating my profile.
At first, I thought it was a convenient and useful way to stay in touch with friends - even those who live far away. But later, I started to find the event invitations annoying. I started to ignore them and found myself logging in less and less.
I don't know if I will log in again. There are certainly useful things about Facebook, but there are also a lot of annoying things too.

Laugh your troubles away and be happy
When we are happy, we laugh. Psychologists say it is a basic method of human communication. They also say we learn to laugh before we learn to speak.
In fact, laughing is not only an expression of our feelings - it's also good for our health. Laughing can reduce stress and relax the body. Furthermore, laughing can strengthen our lungs and is good for the blood circulation. Doctors also believe that laughing is a way to cure illness.
For these reasons, I think we all need to learn how to laugh every day, perhaps by watching a funny movie. Moreover, when we laugh, we can also make other people laugh too. So, let's start laughing.

Give peace a chance, not war
Some people might think that war is a place for heroes to shine, a calamity for humanity or 'diplomacy by other means', but I think war is simply cruel.
Sometimes people fight for power, sometimes they fight for equality. Sometimes they fight for control of territories. But the cost is always the same: lives, blood and resources.
Even though so many people have said violence cannot solve problems, wars still take place - they are taking place right now.
Why can't we give peace a chance? People know the adverse effects of wars and, if countries can maintain good relationships, the world would become a more peaceful place.
