One of the most popular and enduring myths about depression is that depressed people are sad all the time—and that by extension, people who are happy can't be experiencing depression, even if they say they are. It is a mistaken version of depression. Depression doesn't make you sad all the time.

    When I'm having a depressive feeling, I'm not walking around in black clothes, and weeping. I go out with friends. I play jokes. I keep working, and have friendly chats with the people I work with. I read books. Above all, I experience moments of happiness. Yet I feel a strange conflicting pressure. On the one hand, I feel like I need to engage in a sort of sadness for people to understand that I really am depressed and that each day is a struggle for me. Because that way I will appear suitably sad, and thus, depressed—and then maybe people will recognize that I'm depressed and perhaps they'll even offer support and assistance.

    On the other hand, I feel an extreme pressure to perform just the opposite, because sad depressed people are boring and no fun, as I am continually reminded every time I speak openly about depression or express feelings of sadness and frustration. I'm caught in a trap where if I don't perform sadness, I'm not really depressed, but if I express sadness at all to any degree, I'm annoying and boring and should stop being so self-centered. Depression can become your master, but you can slip out from under it occasionally. And many depressed people don't actually spend it fainting dramatically on the couch and talking about how miserable they are.

A huge lake of salty water appears to be buried deep in Mars, scientists reported this week. The presence of water raises the chances of finding life on the red planet. The discovery is based on observations by a European spacecraft. It has excited experts. Water is necessary for life, and scientists have long hoped to prove that it is present on Mars.

Cassie Stuurman is a geophysicist at the University of Texas. In 2016, she found evidence of a huge ice deposit(沉积)on Mars. “If these researchers are right, this is the first time we've found evidence of a large water body on Mars. ”Stuurman said. Researchers are not yet sure how deep the area of water is. So, they cannot say whether it is an underground pool, or just an area of soft and wet soil.

In order to find the water, Italian researchers examined radar signals. The signals were collected over three years by the European Space Agency's Mars Express spacecraft. The results suggest that a 20-kilometer-wide water body lies below ice that is 1.5 kilometers thick. They believe the area is close to the planet's southern pole.

    Mars is very cold, but salt in the water may have kept it from freezing. It is the same as when you put salt on a road to prevent ice from forming. The water would be extremely cold, right at the point where it's about to freeze. And it would be salty. Such conditions are not ideal for life to form. But, she said there are bacteria on the earth that have been able to survive in similar conditions.

Mars has been a popular planet for exploration, with some groups placing instruments on its surface and others examining it from space. In May, NASA launched another spacecraft, the InSight Mars lander which will dig deep into the data under the surface after it reaches a flat area of the planet in November.

    Although it's great to spend vacations seeing the world with family, friends, or a lover, traveling alone can also be completely incredible. A solo adventure has the potential to be life-changing. Here are some reasons you should travel alone at least once.

    If you enjoy meeting new friends, here's your chance; you will likely find some when traveling alone, Since you won't be focused on talking to anyone you know, you'll be more likely to strike up conversations with strangers. Meeting people from different backgrounds opens our minds, expands our world, and can inspire us a lot. You may meet some amazing locals or other adventurers like yourself; either way you're bound to make some new friends during your journey.

    A trip alone can ignite your creativity. Spending time alone with an open mind can be exactly what you need for your imagination to soar. Your enthusiasm and passion for life may sky-rocket from your awesome adventure.

    When traveling with a partner or a group, every idea can be bounced off someone else. When you travel alone, you will learn to be decisive; you will be making every decision alone. From where to eat, to what time to wake up, to what sights to see, and which airline to use, traveling solo forces you to rely on yours truly. As you realize you can make good choices without help from others, you will likely trust your instincts more, and this new found self-assurance and confidence will be helpful in many areas of your life.
