Foreign transport officials from throughout the world head straight for the Netherlands, a country which has more bicycles than people and where bikes are used for three out of ten trips, to learn how to free their cities from the twentieth century problem of traffic crowdedness.

They are brought to cycle-friendly villages, where the safety of cyclists is well protected and engines must give way to bicycles on “bicycle highways”. They also leave copies of the do-it-yourself design handbook “Sigh Up For The Bikes”, a cycle policy guide seen everywhere.

Many countries have set special goals, such as Britain which wants ten percent of London traffic to be bicycles instead of cars compared with a national average of 2 percent.

Although about 50 percent of citizens in Dutch cities use their bikes daily, the Dutch still don’t think it it is good enough. They plan to have 30 percent more bicycle kilometers by the year 2010, while reducing car traffic by 8.75 percent.

In their densely populated lowlands the Dutch have no huge city traffic jams becaue of their love for the bike.

Cycling might be cheap, fast and pleasant in many Dutch towns. It can still be a struggle for survival in today’s rush hour city traffic.

Fear of injury might be a more difficult problem to solve in Britain, where a cyclist is ten times more likely to be killed or injured than in Denmark or the Netherlands.

But if you live, you will live longer. A cyclist can enjoy the health of an unfit person ten years younger, a report by British doctors found.

It is winter and as you have probably noticed, germs are everywhere-runnng noses, sore throats, high fever, headache, nothing quite like the common cold to make you feel miserable.

But experts believe that there is no link between cold weather and catching colds. So why are we particularly weak in this season, and why do we frequently catch colds?

Interact medicine expert, Dr Meenaskshi Jain of Max Hospital says, “One reason could be because people are likely to stay indoors, so the virus can spread easily. Also the viruses are created quickly in wet space.”

The common cold is a viral infection(病毒性感染)that can be caused by any of up to 250 strains of virus, the most common group of which are the rhinovirus that hit the nose. They are responsible for anywhere between a third and half of all common colds.

“They are spread through the nose and respiratory passages(呼吸道), by touching, and by contacting with airborne dusts that are created by sneezing or coughing,” says Dr Jain.

There is no cure for the common cold and antibiotics(抗生素)are of no help. However, there are some premeasures which can help:

Wash your hands regularly, so that germs get killed.

Don’t share your drinking glasses with anyone as this will prevent the spread og the virus.

Drink lots of water to avoid dehydration(脱水).

Make sure to eat enough fruits to improve your immune system.

Get enough sleep and you’ll certainly become stronger.
