Many cities in the world are benefiting from the night activities of a group of people who call themselves guerrilla (游击队) gardeners. Armed with trowels, spades and a van full of flowers and plants, guerrilla gardeners turn abandoned urban land into a blaze of color. In city centre locations where there was mud, weeds and empty plastic bottles, residents often wake up to find that the wasted area has been transformed overnight with brightly-colored bedding plants.

In most British cities, local governments and police turn a blind eye to the effort of the gardeners, whose activities are always carried out under cover of nightfall. And so far, there has been nothing but praise from the astonished and delighted local residents when they find their neighborhood transformed in such a striking fashion.

Not only do the guerrilla gardeners beautify neglected places, they also return regularly to water the plants and weed the flower beds. They also make sure that at least some of the plants they bring are evergreens, which means that the area doesn’t look depressing in the winter months.

The first guerrilla gardener in London was Richard Reynolds, whose day job is at an advertising agency. Mr. Reynolds, a graduate of Oxford University, began his efforts two years ago when he moved to a flat in a tower block in South London. From his balcony, he could see several empty concrete pots, placed by the local governments to contain plants but never used. He went out after midnight and filled the pots with plants, and then planted more flowers in the path leading to the entrance to the block.

He then set up a website to explain his plan and called upon more gardeners to join him. Cash donations flooded in and, more importantly, volunteers rushed to be part of the campaign. Within six months, there were five hundred people in London prepared to come out at very short notice to restore neglected parts of the urban landscape. There are now unofficial but carefully-organized groups in many cities in Britain and North America and there is also a website where would-be urban gardeners can find out the location of the next expedition.

There are plenty of creams etc on the market that help you look younger, but today, Dr Oz is going to show how some people are actually living longer.

“We are going to talk about extreme life extension,” he says. “I am talking in details about allowing us to go into our second century of life with the energy that you have when you are a young person.”

Owing to advances in technology and research on how diet affect the aging process, Dr Oz says it might be possible for some people to live to see their 120th birthdays.

There’s one man in Oprah’s audience who Dr Oz says may become the first man in history to live to be 150 years old. Joe Cordell is one of thousands around the world who believe they’ve found the key to an extreme long life --- calorie restriction leads to a longer, healthier life.

At 59 Joe weighs 130 pounds. He may not look like a person who needs to count calories, but as part of his life extension program, he inspects every mouth of food that passes through his system.

Every day for the past seven years, Joe has limited himself to about 1,950 calories.

He believes that by eating less and restricting his caloric intake, he will trigger a genetic switch that slows the aging process.

Joe doesn’t take away himself of food. Instead, the then 52-year-old father filled up on natural fruits, vegetables and lean proteins(瘦蛋白) that were packed with necessary vitamins and nutrients. “Whenever you are thinking about calorie restriction, you should continually think about getting the most nutritional amount per calorie,” Joe says.

In keeping with this principle, Joe starts every morning with three apples…but he only eats the peels. “Most of the fiber is in the peel, and more importantly, most of the nutrients are in the peel,” he says.

“It is important to eat some nuts with breakfast so that you do take in some fat, some healthy fats,” he says. “I think it helps the absorption of the nutrients, and it is very filling.”

For lunch, Joe usually eats a large salad, loaded with vegetables. At dinnertime, he and his family enjoy lean meat or fish and more vegetables.

When Joe started practicing calorie restriction, he weighed 175 pounds. Since then, he has lost 45 pounds, and he says he hasn’t had a cold in seven years. Though he is in his “golden years”, researchers studying Joe say he has the body of a 20-year-old athlete.

63. According to Joe, the appropriate fat intake may help ______?

A. people lose weight B. feel always full

C. the absorption of the nutrients D. people to live longer
