Alan Smith is blind. He teaches blind children in his country. To show the world that the blind can also do something amazing, he walked across the world's largest salt desert, Salar de Uyuni, only with the help of a GPS.

Walking across the desert is not easy for an able-bodied person, let alone(更不用说) a blind man. Before setting off, Alan spent three years training for the journey.

Is Fresh Air Really Good for You?

We all grew up hearing people tell us to“go out and get some fresh air."

1.According to recent studies, the answer is a big YES, if the air quality in your camping area is good.

2.If the air you're breathing is clean-which it would be if you're away from the smog of cities -then the air is filled with life-giving, energizing oxygen. If you exercise out of doors, your body will learn to breathe more deeply, allowing even more oxygen to get to your muscles(肌肉) and your brain.

Recently, people have begun studying the connection between the natural world and healing(治愈).3.In these places patients can go to be near nature during their recovery. It turns out that just looking at green, growing things can reduce stress, lower blood pressure, and put people into a better mood. Greenery is good for us.
