Scientists say eating less can slow the aging process of cells in the body. The researchers studied mice, not people.
One group was able to eat as much as it wanted. The other animals in the other group are limited to eat. Their diet had 35 percent fewer calories than the first group of mice.
The mice with the diet restrictions(限制) were more energetic and suffered fewer diseases. They were not just living longer, they seemed to stay younger for a longer period of time. When you restrict calories (in mice), there is a direct increase in lifespan - the average age of the animal
But how? The researchers found that fewer calories slow down a natural mechanism in cells called ribosomes (核糖体). Ribosomes are responsible for making important proteins in the cells. But with fewer calories, they slow down.This, in turn, keeps cells and the entire body functioning well.
Earlier studies have suggested a link between calorie restrictions and slowed agingCalorie restriction as a way to slow aging has not been tested in humans. But the main finding for people is the importance of taking care of our bodies And this may help us make better decisions about what we eat.
A. The less we eat, the healthier we are.
B. Researchers studied two groups of mice.
C. This finding is good news if you are a mouse.
D. This gives the cells more time to repair themselves.
E. The findings help to explain how exactly our bodies age.
F. However, this is first to show how the ribosomes can influence aging.
G. Calorie restriction caused real biochemical changes that slowed down the rate of aging.
Life is just like a box. Inside it are happiness and sorrow, failure and success, hope and despair. Life is a learning process. Experiences in it teach us new lessons and make us a better person.
Love
Love plays a key role in our life. Love makes you feel wanted. Without love a person could become cruel and violent.

Being Left-handed in a Right-handed World
The world is designed for right-handed people, but why does a tenth of the population prefer the left? {#blank#}1{#/blank#}
The answer to it remains a bit of a mystery. Since scientists have noticed that left-handedness tends to run in families, it's assumed that left-handedness has a genetic (基因的) component to it. {#blank#}2{#/blank#} In fact, identical twins, who share the same genes, can sometimes prefer to use different hands. There are also plenty of theories on what else might determine which hand you write with, but many experts believe that it's kind of random.
Historically, the left side and left-handedness have been considered a negative thing by many cultures. {#blank#}3{#/blank#} In some areas, the left hand became known as the "unclean" hand. In many religions, the right hand of God is the favored hand. For example, Jesus sits at God's right side. God's left hand, however, is the hand of judgement. Various activities and experiences become rude or even signs of bad luck when the left hand becomes involved. In some parts of Scotland, it is considered bad luck to meet a left-handed person at the start of a journey. {#blank#}4{#/blank#} A person giving directions will put their left hand behind them and even physically try to point with their right hand if necessary. In some Asian countries, eating with the left hand is considered impolite.
{#blank#}5{#/blank#} People come to realize that left-handedness is natural. People even noticed that many famous people are left-handed including Benjamin Franklin, Leonardo Da Vinci, and Charlie Chaplin. Some researchers find out that lefties are more creative and can deal with abstract thinking better. The left-handedness is more easily adaptable to the right-handed world as well. Being left-handed is no longer a sad story now; instead, it is a wonderful gift or maybe it is something you should take pride in.

Fortunately, there are things you can do to gain your self-confidence. G. Having self-confidence can help you become successful in your personal and professional life. |
Self-confidence is defined as a feeling of trust in one's abilities, qualities, and judgment. {#blank#}1{#/blank#} Whether you apply for a promotion in work or sign up for a cooking class, believing in yourself is the key to putting yourself out there. However, not all people are born confident. {#blank#}2{#/blank#}
Stop comparing yourself to others. Whether you compare how you look to your friends on Facebook or you compare your salary to your friend's income, comparisons aren't healthy. Researchers found that people who compared themselves to others, experienced envy. {#blank#}3{#/blank#} It can be a terrible cycle. When you notice you are drawing comparisons, remind yourself that doing so isn't helpful. Everyone is running their own race and life isn't a competition.
{#blank#}4{#/blank#} It's hard to feel good about yourself if you're abusing your body. Skimping on sleep, eating an unhealthy diet, and lacking exercise will do harm to your well-being. Studies consistently show physical activity boosts confidence. A 2016 study published in Neuropsychiatric Disease and Treatment found that regular physical activity improved participants' body image. And when their body image improved, they felt more confident.
Embrace (拥抱) self-doubt. Sometimes, people put off doing things—like inviting someone on a date or applying for a promotion—until they feel more confident. But sometimes, the best way to gain confidence is by doing. {#blank#}5{#/blank#} That doesn't mean you shouldn't prepare or practice, of course. If you have a big speech coming up, practice in front of your friends and family so you'll gain some confidence. But don't wait until you feel 100 percent confident before you proceed. You might never get there.
