Why Dogs Bury Their Favorite Bones
You may find it crazy that your dog buries his favorite bone or chew toy, only to dig it up a day or two later, but there is actually a reason behind it—it is simply in their nature. For thousands of years, dogs have buried their bones. The practice itself started long before dogs were even pets when they had to bury bones to survive.
When dogs lived in the wild, sometimes food was scarce. If they were able to find food, dogs became very protective of it. Sometimes they would have more bones than they could eat for one meal. To keep other dogs and animals from stealing their bones, dogs would bury them in the ground. When it was time for the next meal, they would dig up their bones and enjoy them again. This would continue until the bones were gone.
Even though most dogs have plenty of food to eat today, their instincts still tell them to bury their bones and favorite toys. They do this to keep other dogs and animals from stealing them, just like their ancestors did. Some dogs keep at least two bones buried at once. When they want to dig up one, they will bury one more. This may leave a backyard full of holes and bones.
How do dogs decide where to bury their bones? A dog cannot bury a bone just anywhere. He must first find the perfect spot. This involves using his nose to find a spot that is free from other dogs and animals. Often it is near a tree or a large rock, but it could be anywhere in the yard. Once the dog finds the perfect spot, he uses his front paws to dig a hole, drops the bone in and covers up the hole to protect his treasure.

Public Wi-Fi Users Neglect Safety
A recent survey shows that 25% of Internet users have done online banking through public Wi-Fi in the last three months. It also shows that 27% have bought a product or service with a credit card this way.
Experts worry that hackers (黑客) will take advantage of these practices. Doug Shadel said that hackers usually attack in two ways. They may create Wi-Fi hotspots that have the same name of the ones you trust, such as a hotel or a coffee shop. They may also provide a stronger Wi-Fi signal to get between you and the safe hotspot. In either case, the hackers can see your email, credit card information, user names and passwords.
Sometimes hackers just set up their electronic traps near a business where people enjoy the free Wi-Fi. "In most cases they are after your personal information," Shadel said. "If you use the same user name and password for many accounts, they can get into them all. It's possible for any hacker to do it. The software to hack into a Wi-Fi network is available at little or no cost."
"It's difficult for people to know if a Wi-Fi network is safe," Shadel said. "So you should just think they are not. Any shared Internet access, free or paid, carries the same level of risk. It is safe only when you or someone you trust directly controls it."
Shadel sometimes checks email through public Wi-Fi. But he never does any banking that way. In an unfamiliar place, he uses a Virtual Private Network (VPN). "This service creates a passage between your device and a safe place on the Internet," he said.

I Use Every Second Before I Go to Work
① I wake up at 6 a.m. every day. The first thing I do when I wake up is grab my smartphone and take it to bathroom with me, where I start my day by consuming quite a lot of information to some websites, but the main site that I focus on during this time is Nuzzel, a collector of headlines and links. I recommend everyone look into it if they don't have time to properly focus on every website individually.
② After visiting those sites, I head to Twitter, my No.1 outlet for communication with the public. Twitter is becoming a listening platform. There is such a volume of information on the platform that you need pay attention to. So I spend a great amount of my morning responding to people and starting conversations.
③ After all this comes my workout (锻炼) with my trainer. I usually work out for about 45 minutes. The specific workout routine varies depending on the day of the week, what I ate, and how much I've been traveling.
④ After the workout, I head back home to get my children ready for school. I say bye to them and give them each a kiss before they leave. Then, I'm off to my office, often before 9 a.m..
⑤ In the car to my office, I call my mom, dad or sister. I talk to them just to learn what they're up to. I really value those small moments. By the time I step into my office, so much is going through my head. My day starts the minute I open my eyes.
