1 . We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us?   It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.

Blue light is a type of electromagnetic radiation with a very short wavelength that produces a high amount of energy. While it’s true that light can damage our eyes under certain circumstances, there’s no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue-light-blocking glasses are so popular. So, do the glasses work?

“Everyone is very concerned that blue light may be causing damage to the eye, but there’s no evidence that it may be causing serious damage, ” Dr. Rahul Khurana, a clinical spokesman, told Business Insider.

Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn’t harmful, then why are we constantly rubbing our eyes when we’re looking at our screens?   The answer is eyestrain (眼疲劳). More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems isn’t the cause. Instead, our eyes are so strained because most of us blink less when we stare at our digital devices. So, if eyestrain is the real issue, blue-light-blocking glasses are probably of little use.

From the work I did during the summer vacation, I understand that money was not easy to earn. I felt it a shame to wasting food. For the old generation, we advocate saving money.

9 . A simple project to help a family in need stopped Luck Mickelson in his tracks. In 2012, he and his family were inspired to build and donate a bunk bed, one bed on top of the other, after learning there were local children who slept on the floor. Shocked to discover how widespread this need was in his community, Mickelson founded Sleep in Heavenly Peace, a nonprofit that builds and delivers beds to children in need.

Born and raised in Idaho, Mickelson, now 41, had a thriving career. He coached his kids' sports teams and fished in the nearby river. But when he met children who were sleeping on the floor, his peaceful life changed course.

Using safety guidelines and his daughter’s bunk bed as a model, Mickelson started buying wood and supplies to build beds with his own money. He recruited friends and family members to help around the holidays. As the word spread, interest and involvement from his and other communities flooded-along with Mickelson's bunk bed output. "That first project, we built 11 bunk beds in my garage, "he said. "The next year, we did 15. Then it doubled every year. In 2017, we built 612 bunk beds.”

With the motto "No kid sleeps on the floor in our town”, the nonprofit and its more than 65 branches have built and delivered more than 1,500 free beds to children across America. But along with the rapid growth, Mickelson was faced with a tough choice: advancing his career or his nonprofit. He chose the latter and went from making "great money to zero money". He's never looked back. "I found that the need I have isn't financial, "he said. “The need I have is seeing the joy on kids’ faces, knowing that I can make a difference.”
