1 . I’ve never had a great sense of direction. And I often wander into shops and, upon coming back out, can’t remember which way I’ve come from — left or right? Many people are like me, and why do some constantly have no idea where they are?
The hippocampus (海马体) is a region of the brain associated with memory and involved in sense of direction. And a nearby region has also been associated with sense of direction. There are four known types of navigation-related neurons (神经元), found in these regions place cells, grid cells, border cells and head direction cells.
In short, you can think of place cells as an internal cognitive (认知的) map; they identify where you are. Grid cells are like a GPS system in our brain; they tell us about the relationship of this place to other places we’ve been to. Border cells respond to the presence of environmental boundaries at a specific direction and distance from us. Lastly, head direction cells are activated when our head faces a specific direction. These cells will fire electrical impulses when we enter familiar locations, with each group of cells relating to a specific place.
Our reliance on GPS and smartphones may have decreased the ability to use our internal maps. Older adults who regularly used GPS had less activity in their hippocampus, compared with those who did not use GPS. They also performed slightly worse in a cognition test. In contrast, a study involving London taxi drivers found they significantly larger hippocampus than ordinary people.
You can improve your way-finding ability specifically by practicing the skill, according to Aziz, PhD of neurology at Temple University School of Medicine. “The more you get out and go to places, the better,” he says. Physical exercise improves the blood flow to the brain, while mental exercise, such as doing puzzles or learning a new language, stimulates the development of new nerve cells and connections in your brain.

6 . Located deep in the mountains of Chong yang county of Hubei province, the Qingshan Reservoir (水库) looks like a river with many twists and turns.
For Wang Zhijun, a primary schoolteacher who has served the villages near the reservoir for 28 years, the river is an obstacle (障碍) to be overcome. He doubles as a ferryman to help students shuttle (往返) back and forth via boat.
A recent video of Wang went viral on social media and moved many.
He became a teacher at the primary school in Panshan village in 1995. With water in three directions, the village occupies a sort of peninsula (半岛), even though it’s high on Qingshan Mountain.
Wang travels 500 meters of mountain roads to carry water to the school for the students. He rows a boat to pick them up for school, and then he takes them home afterward. Wang said he had suffered many falls with the water buckets, but the ferry trips have always been safe.
With development of the local economy, Panshan Primary School merged with the Chichong Primary School on the opposite bank of the reservoir in 2017. Wang could drive to pick up most of the students, but a few depend on his boat.
He said he had been given several opportunities to get out of the area for better career development, but he felt responsible for the kids and stayed.
Panshan and Chichong villages together have more than 1, 000 residents. Wang is proud that 40 of his students eventually entered college. “My ultimate dream is to send them out from the mountains through education,” Wang said. Meanwhile, he is proud that six of the 40 college students returned to their hometown and became teachers themselves.

In 2014, it was listed as
An old and fragile woman approached a very busy road intersection. She stepped slowly forwards. She paused at the sidewalk’s edge, grasping a heavy bucket filled with fresh red apples. She aimed to cross the street.
The way to the intersection before her seemed like a tough journey. The traffic lights changed regularly, and the flow of cars seemed to be non-stop for the old woman. She knew she had to cross the street to reach her destination, a small grocery store on the other side, where she sold her apples to make ends meet.
As she slowly made her way to the crosswalk, she held the handle of the bucket. A kind-hearted driver in the first car, recognizing her struggle, stopped well before the sidewalk, allowing her to cross safely. Grateful for this act of kindness, the old woman nodded and offered the driver a slight smile as she inched forward.
A second car, in the next road, also came to a stop. Its driver also witnessed the old woman’s slow progress. The kindness of strangers warmed her heart, and with their help, she moved another step closer to her destination.
However, the third road was a different story. As the old woman moved carefully further into the road, a speeding car approached, its engine making loud sound like a beast. Panic flowed through the old lady as she realized the approaching danger. The driver of the third car had not noticed her until the very last moment.
With a jolt (颠簸) of terror, the old woman’s holding on the bucket weakened, and the bucket slipped from her weak grasp. The bucket fell to the ground, releasing its goods of apples, which scattered (散开) in all directions. The sound of the crashing bucket and rolling apples echoed through the busy city traffic.
In the emergent time, the driver of the speeding car stepped on the brake to a stop just inches from the old woman. The drivers’ heart pounded in their chest as they realized how close it had come to a tragedy.
