The next time someone asks you where the biggest ocean is, point them toward Jupiter. While earth harbours about 320 million cubic miles(1,333 cubic km)of water, our planet is practically a desert compared to the rest of the Solar System.

    A moon of Jupiter called Europa, for example, which is roughly the size of our own Moon, likely hides a subsurface ocean with more than twice as much water as there is on Earth.

    Yet even that pales into insignificance in comparison to Europa's neighbour Ganymede; more than 30 times as much water as our home planet is thought to reside there as liquid and ice.

    And scientists keep finding more water wherever they look. On September 28, researchers reported that Dione — a small moon of Saturn — probably has a subsurface ocean, too.

    To see just how Earth stacks up against other ocean worlds, Business Insider contacted Steve Vance, a planetary scientist at NASA's Jet Propulsion Laboratory who's calculated the numbers on just how much water might be out there.

    In order of how much water they have, from the least to the most, they are: Enceladus, Dione, Earth, Europa, Pluto, Triton, Callisto, Titan, and Ganymede. Mimas, a moon of Saturn, and Ceres, the largest asteroid in the Solar System, are also thought to have subsurface oceans —but scientists aren't yet sure how big each one might be.

    Today, a man talked very loud on his phone on a train between Malvern and Reading, making many passengers upset. I wonder how he would react if I were to read my newspaperoutloudonthetrain, Ihave never had the courage to do it, though.

    Why not give it a try? Perhaps you should take lessons on a

    musical instrument. The late musician Dennis Brian is said to have

    asked a fellow train passenger to turn off his radio. When his

    request was refused, he took out his French horn(号) and started to practice.

    I don't see how musical instruments can help improve manners in public. Don't do to others what you wouldn't like to be done to yourself. Once, a passenger next to me talked out loud on his mobile phone. I left my seat quietly, giving him some privacy to finish his conversation. He realized this and apologised to me. When his phone rang again later, he left his seat to answer it. You see, a bit of respect and cooperation can do the job better.

    I did read my newspaper out loud on a train, and it turned out well. The guy took it in good part, and we chatted happily all the way to Edinburgh.

    I have not tried reading my newspaper out loud on a train, but ,several years ago, I read some chapters from Harry Porter to my bored and noisy children. Several passengers seemed to appreciate what I did.

    Certain activities can be good or bad for our brains, so let's see which of the seven habits you should carry on doing or give up.

Best Ways to Quit Smoking

    Not sure how to quit smoking cigarettes? Try the following ways to stop smoking and start your path towards a healthier, smoke-free life.

    Post this list in a visible location in your house.

    Whenever you're tempted to light up, take a look at all the ways smoking can damage your health:

    Increases risk of heart disease, stroke, high blood pressure.

    Reduces levels of folate, low levels of which can increase the risk of heart disease, depression, and Alzheimer's disease.

    Affects mental capacity and memory.

    Contributes to thin bones.

    Affects ability to smell and taste.

    Increases risk of depression in adolescents.

    To minimize cravings (欲望), change your routine.

    Sit in a different chair at breakfast or take a different route to work. If you usually have a drink and cigarette after work, change that to a walk. If you're used to a smoke with your morning coffee, switch to tea, or stop at Starbucks for a cup of java—the chain is smoke-free. You might even work better in coffee shops！

    Tell your friends, coworkers, boss, partner, and kids how you feel.

    Don't bottle up your emotions. If something makes you angry, express it instead of hiding it with cigarette smoke. If you're bored, admit to yourself that you're bored and find something energetic to do instead of lighting up.

    Make an appointment with an acupuncturist (针灸师).

    There's some evidence that auricular acupuncture (i. e., needles in the ears) controls cigarette cravings quite successfully. You can even do it yourself by taping "seeds" (small beads) onto the acupuncture points and squeezing them whenever cravings arise. Acupuncture can treat these other conditions, too.

    I'm not so sure I like my friends any more. I used to like them — to be honest. We'd have lunch, talk on the phone or exchange e-mails, and they all seemed normal enough. But then came Facebook and I was introduced to a sad fact: many of my friends have dark sides that they had kept from me.

    Today my friends show off the more unpleasant aspects of their personalities via Facebook. No longer hidden, they're thrown in my face like TV commercials — unavoidable and endless advertisements for the worst of their personalities.

    Take Fred. If you were to have lunch with him, you'd find him warm, and down-to-earth. Read his Facebook and you realize he's an unbearable, food-obsessed bore. He'd pause to have a cup of coffee on his way to save a drowning man — and then write about it.

    Take Andy. You won't find a smarter CEO anywhere, but now he's a CEO without a company to lull. So he plays Mafia Wars on Facebook. He's doing well — level 731. Thanks to Facebook, I know he's playing about 18 hours a day. Andy, you've run four companies — and this is how you spend your downtime(业余时间)? What happened to golf? What happened to getting another job?

    Take Liz. She is positive that the H1N1 vaccine(甲流疫苗) will kill us all and that we should avoid it. And then comes Chris who likes to post at least 20 times a day on every website he can find, so I get to read his thoughts twice, once on Facebook and once on Twitter.

    In real life, I don't see these sides of people. Face to face, my friends show me their best. They're nice, smart people. But face to Facebook, my friends are like a blind date which goes horribly wrong.

    I'm left with a dilemma. Who is my real friend? Is it the Liz I have lunch with or the anti-vaccine lunatic(狂人)on Facebook? Is it the Fred I can grab a sandwich with or the Fred who weeps if he's at a party and the wine isn't up to his standards?
