Eating 40 percent less food could extend a person`s life by 20 years, according to scientists.
Researchers at the Institute of Health Ageing at University College London are developing a treatment that they hope will fight the `disease` of getting older.
They are looking into how genetics（遗传学） and lifestyle can affect ageing and add years, possibly decades, to a person`s life.
Age-related diseases such as cardiovascular disease, cancer and neuro degeneration can also be treated, it is claimed.
They want to find out how the life of a rat can be increased by up to 30 percent simply by reducing its food intake.
Researcher Dr. Piper told the Independent : `If you reduce the diet of a rat by 40 percent it will live for 20 or 30 percent longer. So we would be talking 20 years of human life. This has shown on all sorts of animals, even Labradors(a kind of dog).`The scientists are also studying fruit flies, which share 60 percent of human genes and age in a similar manner, and mice.
They have already made the healthy lifespan(寿命) longer in both flies and mice by using drug treatments and a balanced diet. It is hoped that this combination will also work to extend(延长) human life. Dr. Piper said: `If we discover the genes involved with ageing, we should be able to delay ageing itself. This is what we`ve found.`
He added that the field of research into extending life is only a decade old, so remains `in theory . It is their special approach to treating all age-related diseases caused by the `disease` of ageing itself that sets their research apart.

Have you ever noticed that the more you have the more you want? Let’s face it. Thinking our life is good enough doesn’t come naturally to many people. When we have high expectations of everything in life we will run into disappointment. Only when we are aware that needs are different from desires can we live with satisfaction. Here are a few ideas to help you be happier with what you have and who you are.
Focus on what you are thankful for. Most people want things to be better than they are, or when things are going well, we forget to appreciate what we have. Learn to reflect on how much better things are than they could be. Focus on what you are thankful for. Write down 5 things you are grateful for right now.
When we hold onto regrets from decisions we have made, it can really poison our well-being. Many people regret something they can no longer change, which ends up holding them back from moving forward in a more positive manner. What happened in the past is done and gone, so work to stay present and be mindful of the current moment to find more joy and fulfillment.
When we use other people as the measuring stick for our personal success and quality of life we are likely to be less satisfied. Social comparisons can provide useful information when we try to learn from others, but they also hold our perspective in a discontented position. Compare yourself less with others so you can be satisfied more.
When you are focused on your big ambitions and future goals you might elide the daily pleasures that surround you. Learn to slow down and absorb the wonder and beauty around you. Stay present and focus on the task you’re undertaking at the moment. Don’t let the life pass you by because you’re always on the go and distracted by ambition.
Practice looking at life through the lens of contentment and it will become more natural.
1.How can we live with contentment?
A. To change our lifestyle.
B. To have a motivation in life.
C. To give less attention to what we are grateful for.
D. To realize the difference between needs and desires.
2.What’s the main idea of Paragraph 3?

A. Make time for simple pleasures.
B. Learn from successful people.
