How old is “old”? The answer has changed over the years. Two Hundred years ago, you were old at 35. At the beginning of the 20th century, the average life span (平均寿命) was 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is still thought young.

          So, how old is “old”? The answer is one you’ve heard many times, from all kinds of people. “You are as old (or young) as you feel.” Your age simply tells you how many years you have lived. Your body tells you how well you’ve lived.

         “Nobody grows old by living a number of years,” wrote a writer. “People grow old when they don’t have their ideals (理想).” People shouldn’t have the wrong ideas about aging. Sometimes, older minds can be as bright as young minds. Alice Brophy once said, “It makes me unhappy when people say, ‘You look young for your age.’ What does that mean? You know you can die old at 30 and live young at 80.”

Take a look at the label(标签) on almost any bottle of milk and you may see the word PASTEURIZED. What does that mean? Let’s find out by meeting Louis Pasteur.

Louis Pasteur was born in 1822 in a little town in France. As he grew up, he loved to paint. He loved to look at the world around him. When he went to college in Paris, he showed interest in looking through a microscope. A microscope makes things look a lot bigger; it lets you see things you can’t see just with your eyes. Looking through a microscope, Pasteur found a living world in a drop of water. He saw and drew pictures of the small living things -- he called them “microbes” or “germs”-- that crowded in a drop of water.

One day a winemaker came into the lab, hoping that someone could help him with his problem. “Sometimes my wine tastes delicious, but sometimes terrible,” he said to Pasteur. “Can you help me find out why?”

Pasteur put some drops of the wine under the microscope. He noticed that the terrible wine had some unusual germs. If he killed these germs, maybe he could keep the wine from turning terrible. He tried with different ways to kill the germs. In the end he found heating (加热) the wine seemed to work best. The winemaker tried it, and every bottle of wine tasted good.

Pasteur’s idea worked for other people, too. When farmers heated milk, it didn’t turn bad so quickly. When breweries heated beer, it tasted better. People called it “pasteurization” ---heating a liquid to kill bad germs. Aren’t you glad that the milk you drink has been pasteurized?

Yesterday the police were joined by more than 20 volunteers in the continuing search for the two missing teenagers, Vicky Gray and Tom Hunter, and their guide, Gavin Jones. The police said that they had disappeared during an adventure tour of Cape York Peninsula.

This was the second day of the search and the police were now very worried about the safety of the three missing people.

The police said that the search had covered a wide area, but the rainforest was thick and their work was made harder by the recent rain. Later on Chief Inspector (警官) Roger Fleet said, “The travelers had a radio with them. If they had been in trouble, they would have called us.”

The three travelers left Cooktown very early on Saturday morning in a Toyota car. They took a small dirt road that runs down to the Daintree River, a dangerous river full of crocodiles (鳄鱼). Chief Inspector Roger Fleet said the tourists wouldn’t have got into trouble if they had stayed on the main road.

A photo of Vicky and Tom was found by a policeman under the “Be Careful about crocodiles” sign near the river. Why was the photo left behind? This is just one of the unanswered questions. Other questions are: Why was the Toyota parked and locked at the edge of the rainforest? The police said that the travelers had left a map of the area behind. Why? Why had someone drawn a cross on the place where the car is? Is this a sign? What does it mean? If anyone can give information or has seen these three young people, contact the local police in Cooktown.
