1 . The cost of living in countries like the US, Britain, Australia or France has skyrocketed in recent years. However, if you’re willing to leave your country and explore life in other areas, there are many countries boasting an extremely cheap and low cost of living. Check out the following countries when planning your next move.
Ecuador
Ecuador is similar to the United States in many ways, and as a result has become a popular American getaway. They even use the US Dollar for their currency. In this country, it’s cheaper to eat out every day than cook for yourself on a budget in the US. You can even buy a building for around $ 50, 000 and hire someone to look after it while you’re away.
Mexico
Although the country is known for its poverty ridden streets, there $are many wealthier areas that provide every facility you might need. You can live off a mere $ 700 to $ 800 a month in Mexico, and this includes rent for a nice place, facilities, food, and any sightseeing.
Argentina
Argentina has been a popular tourist destination for many years. It has great restaurants, a rich history, and many places to explore. Not to mention, it’s not very expensive to live here. A decent sized home can cost around $ 139, 000, which is relatively cheap in relation to homes in the United States.
Vietnam
Vietnam has also become a popular tourist destination in recent years. There are many million-dollar luxury homes by the beach, but you can find a modest flat or a small home for around $ 25,000 to $ 50,000 if you search in the right areas.

2 . What do you plan to do when you retire? Keep working? Get more exercise? Or learn something new? You may put them on hold. There's a chance that, sooner or later, you might have to move further than you were thinking, as far as Mars.
On Thursday, National Geographic will show the first-ever Mars show home, giving earthlings (地球人)an idea of what their life could look like on the Red Planet. In the not-so-distant year of 2037, the igloo-shaped structure could be the home of your future.
It shows a house built using recycled spacecraft parts and Martian soil, called regolith, which has been microwaved into bricks. Some parts of the home are recognizable — a kitchen, a bedroom — but there are fundamental differences that are important to human survival.
As the Martian atmosphere is around one hundredth as thick as the Earth’s, people will need permanent (永久的) shelter from the sun；society will move largely indoors. Most buildings will be connected by underground passages and the houses won't have windows. The homes will have simulated solar lighting, or natural light that has been bent several times. Walls will need to be 10 to 12 feet thick, to protect people from dangerous rays (光线)that can pass through six feet of steel, and a double air-locked entrance to keep the home under proper pressure.
"We don’t think of our houses as things that keep us alive, but on Mars your house will be a survival centre, 99 says Stephen Petranek, author of How We’ll Live on Mars. This is not just the stuff of sci-fi. “10 to 20 years from now there will certainly be people on Mars,” Petranek says.
“We’ve had the technology for 30 years to land people on Mars, but we haven’t had the will, ”Petranek says. But two main factors have “completely swung public attitudes”.
The private companies’ participation has forced government agencies to speed up their game, and influential films such as Gravity and The Martian have caught society’s eye.

3 . Nowadays, we can read almost all "truths" on social media sites. But are they really reliable? Sites such as the micro-messaging service, the social networking site and the photo-sharing app Instagram might "misrepresent the real world", according to a study by computer scientists from McGill University and Carnegie Mellon University.
The scientists warn that gathering information about public views and trends from these sites is unwise. There are still large parts of the population who do not take part in social media activities. Also, there's a risk that many social media users are under-represented. Instagram, for example, appeals to younger adults in urban areas while Pinterest is used mainly by females aged 25 to 34. And only 5 percent of the micro-messaging service users are over 65 years old, according to the study. However, this is not the only issue, according to the scientific team. The design of a website can influence how people behave online, creating what the researchers call "Internet bias". For example, micro-blogging sites such as Weibo promote "popular" stories. It saves time for some but it also limits readers' choice of what they see. In the end, many people open those stories and make them more "popular". But it's not because they choose those stories. Rather, it is because the content is right in front of them.
Besides, it's possible that not everyone on your social networks is real. There might actually be a few fake accounts among them. Fake "bots" pretend to be humans and are often included when measuring or predicting human behaviors online.
The findings might be more important than you would think, since many social media studies are used to inform and justify decisions and investments among the public and in industry and government, according to Derek Ruths, an assistant professor of Computer Science at Mc Gill University.
If the team is right, you might have to think carefully next time you say, "It's true, you know; I read it on Weibo."
