     The Australian crocodile is the largest crocodile in the world. It can grow up to seven meters long, and the biggest can weigh up to 1,000 kilogram. It has only two muscles to open its mouth but 40 to close it! What makes crocodiles so dangerous is that they attack extremely quickly, and they take their victims under the water to drown them. They usually attack in the water, but they can suddenly come out of a river and attack animals or people. And they can run on land as fast as 17 kilometers per hour.
     Every year in Australia there are crocodile attacks on humans. Two years ago a 24-year-old German tourist died when she went for a swim in a lake. Although there were signs warning people that there might be crocodiles, the woman and her friends decided to go for a midnight swim. The woman suddenly disappeared, and the next morning her body was found. Near it was a four-meter long crocodile. And only last month two Australian boys watched in horror as their friend was killed by a crocodile when they were washing their bikes in a river. They climbed a tree and stayed there for 22 hours while the crocodile waited below.
      But you can survive a crocodile attack. Last year Norman Pascoe, a 19-year-old, was saved from a crocodile when his aunt hit it on the nose. Norman’s aunt said: “I hit it and I shouted, ‘Help!’ The crocodile suddenly opened its mouth and my nephew escaped.”

Depression drains your energy, hope, and drive, making it difficult to take the steps that will help you to feel better. Sometimes, just thinking about the things you should do to feel better, like exercising or spending time with friends, can seem exhausting or impossible to put into action. It’s the Catch-22 of depression recovery: the things that help the most are the things that are the most difficult to do. There is a big difference, however, between something that’s difficult and something that’s impossible. While recovering from depression isn’t quick or easy, you do have more control than you realize—even if your depression is severe and stubbornly persistent. The key is to start small and build from there. You may not have much energy, but by drawing on all your reserves, you should have enough to take a walk around the block or pick up the phone to call a loved one, for example. Taking the first step is always the hardest. But going for a walk or getting up and dancing to your favorite music, for example, is something you can do right now. And it can substantially boost your mood and energy for several hours—long enough to put a second recovery step into action, such as preparing a mood-boosting meal or arranging to meet an old friend.

As we all know, millions of people receive psychotherapy to deal with psychological problems and to free themselves   41   emotional suffering. Typically, they will sit in an office with a therapist who is a member of a profession such as psychology or social work, and try to talk their ways to an improved state of mental health. The therapist,   42   , will use widely respected techniques such as helping them see the truth about their irrational beliefs or delving into the depths of the unconscious to reveal their hidden motivations. Unfortunately, people who seek out this kind of therapy often find that the therapy itself   43   emotional suffering, evoking difficult feelings such as vulnerability, anxiety, and sadness, and forcing them to   44   with therapists whose role automatically gives them the upper hand. Many people go through it anyway because they hope the truth will set them free, and they see the therapist   45   an expert who knows how to get at the truth of the mind.
