Before I studied psychology, I used to think that people would laugh when funny things occurred. While I was right about that, I discovered there are lots of other psychological factors that make people laugh other than the funny part of a joke. When someone laughs at a joke, there will usually bemore than one reason that makes him laugh—and the more reasons there are, the more powerful the joke will be.

    I was attending a stand-up comedy show in Egypt, and when the man started to make fun of pedestrians crossing streets, everyone laughed their hearts out. The main reason those people strongly laughed was that almost allof them felt angry towards pedestrians who crossed streets carelessly. The joke wasn't only funny, it also made the audience feel that they were right about being angry at those pedestrians. That is, people were laughing both because ofthe funny joke and because of the happiness experienced as a result of the psychological support they got.

    The better a joke makes a person feel, and the more it includes other psychological factors, the more the person will like it. For example, if you envy one of your friends, and someone tells a joke that is funny and, at the same time, makes your friend seem stupid, then you will probably laugh atit louder than if you weren't jealous of him.

    In short, we don't laugh only when we hear something funny; we also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All Iwant to explain is that if your joke supports a person's emotions, he will certainly like it a lot.

    Old age may not sound exciting.But recent findings offer good news for older people and for people worried about getting older.Researchers found that people become happier and experience less worry after they reach the age of fifty.In fact，they say by the age of eighty­five，people are happier with their life than they were when they were eighteen years old.

    The findings came from a survey of more than three hundred forty thousand adults in the United States.The Gallup Organization questioned them by telephone in 2008.At that time，the people were between the ages of eighteen and eighty­five.The researchers asked questions about emotions like happiness，sadness and worry.They also asked about mental or emotional stress.

    Arthur Stone in the Department of Psychiatry and Behavioral Science at Stony Brook University in New York led the study.His team found that levels of stress were highest among adults between the ages of twenty­two and twenty­five.The findings showed that stress levels dropped sharply after people reached their fifties.

    The study also showed that men and women have similar feeling patterns as they grow older.However，women at all ages reported more sadness，stress and worry than men.

    Researchers say they do not know why happiness increases as people get older.One theory is that，as people grow older，they grow more thankful for what they have and have better control of their feelings.They also spend less time thinking about bad experiences.

    Professor Stone says the emotional patterns could be linked to changes in how people see the world，or maybe even changes in brain chemistry.

    The researchers also considered possible influences like having young children，being unemployed or being single.But they found that influences like these did not affect the levels of happiness and well­being related to age.

    The hit movie Notting Hill（诺丁山）begins with a famous scene. Hugh Grant bumps into Julia Roberts and spills orange juice all over her. After the collision, Grant repeatedly says, “I'm so sorry. I'm so sorry.”

    His actions in this scene are very British. If Roberts' character were from the Britain, than she would probably apologize repeatedly as well – even if the crash were not her fault. But this doesn't happen in the movie, as Roberts is from the US.

    A report in The Telegraph once said that three quarters of British people apologize when they bump into someone in the street – regardless of whether they are responsible or not. In fact, Britons use “sorry” in many situations. For example, if they mishear someone, they say “Sorry?” The person they are talking to will also apologize by replying, “No, I am sorry!” This can go on for up to five minutes as they compete over who is the most sorry.

    Why are Britons so sorry? Mark Tyrell, a psychology writer in the UK, thinks that their apologetic tendencies are rooted in British class system. “We say sorry because historically the new middle class in Britain had to apologize for not being the working class, but also for really being the upper class.” Another theory is that they apologize to avoid conflicts. For example, if they bump into someone, he might get angry. To avoid this, they instantly say “Sorry!”

    True manners are about being considerate, and today's constant use of apologizing shows that we are perhaps not as thoughtful as we once were. The word “sorry” has lost some of its meaning.

    Do you see my point? Sorry, it might just be a British thing.

    You may laugh it off if someone told you that extreme weather disasters were actually a child's tricks. But El Nino, meaning “little boy” in Spanish, could be about to cause trouble

    A recent statement from the US National Oceanic and Atmospheric Administration warned ofa strong El Nino event that may be similar to the strongest in modern times. Scientists believe that evidence shows a more than 90 percent chance that it is coming — and it's going to be big. “If this lives up to its potential, this thing can bring a lot of floods, mudslides（泥石流）, and trouble,” said Bill Patzert, a NASA scientist.

    El Nino is a climate event occurring in the Pacific Ocean. The wind usually blows strongly from east to west due to the rotation（旋转）of the Earth. This causes water to pile up in the Western Pacific and pulls up colder water from the boom in the eastern part. However, in El Nino years, the winds pushing the water get weaker and cause the warmer water to shift back toward the east. This warms the ocean as it travels before finally reaching the shores of North and South America. In an El Nino event, the waters of the eastern Pacific can be up to 4 degrees Celsius warmer than usual.

    Most El Ninos last from 9 to 12 months and their effects are felt around December. They don't happen every year though, usually between every two to seven years.

    Last seen in 1997-98, El Nino caused severe droughts in Australia, the Philippines and Indonesia, as well as deadly floods in Peru and Ecuador. The world also heats up during an ElNino-1998 became the warmest year on record at the time. If the current trend continues, 2015 is almost certainly to become the hottest year yet again.

    A strong El Nino also affects hurricane seasons around the planet. The warmer the Eastern Pacific is, the more hurricanes it gets. The Western Pacific, on the other hand, tends to see more and stronger typhoons.

    The weather isn't the only thing that's affected. Warmer surface waters in the Eastern Pacific make the cold-water fish swim away and damage the fishing industry in much of Latin America.
