     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.

1. 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

2. What can we learn about Joe since he started the calorie restriction program?

A. Joe counts the amount of every meal

B. Joe has never had a cold

C. Joe eats three apples every morning

D. Joe has a large salad with vegetables for dinner

3. The underlined word "trigger" in paragraph 7 can probably be replaced by ______.

A. turn on

B. break down

C. take up

D. cut off

4. According to the passage, the extreme life extension refers to _______.

A. living very long even sick

B. how to make people lead a happy life

C. living long and having a healthy body

D. how to arrange our foods every day
