“ Can we go now, Momma?” little Susie asked, pulling on her mom's arm. Her mother did not answer, only stared blankly at the scene below. Crowds of people marched about with what looked like picket(警戒队) signs. Other people gathered around them, shouting angry words that she couldn't make out from this distance. This relatively small town in Missouri had never seen so much action. She and Susie were standing at the top of the only high rise building in town for Susie loved to try to find their house among the rows and rows of little boxes.

    “Momma? ” Susie said in a frightened voice, two seconds before a gun shot went off, making her scream at the top of her lungs. Her mom grabbed her and held her over her shoulder as the tears started pouring. “What was that? I'm scared, Momma!!”

    “Sh Sh Sh,” her momma whispered in a soothing tone, rubbing her daughter's hair. “It's just a bad dream, baby. She said both to herself and Susie.

    Susie looked at her with confused eyes at the same time a fight broke out among some members of each group. The little girl gasped in surprise. “Why are those ants fighting , Momma?”

    “Those aren't ants, sweetie; they're people, or, at least they're supposed to be.”

    “I don't understand what's going on! I'm scared!!” the four-year-old child clung to her momma. “It looks like they're dancing, momma.”

    “Yeah, it sort of does, doesn't it?” her mother said with an air of disbelief. How could the expression of heated anger be so beautiful? It was so wondrously unexpected that it brought soft tears to her eyes.

    “Why are you scared, Momma? It's just bugs dancing,” Susie said with an innocent smile, wiping away her mother's tears.

    The decisions that we make shape us throughout our lives. No matter what decisions we make, good or bad, each one puts us on a new road in the future. Make a bad decision? No problem. Learn from the decision and make another decision to get on a different path. This is advice that I got from Tony Robbins in his book Awaken the Giant Within. This is a book that I recommend(推荐) to anyone wanting to develop a fire to make changes in their life. It helped me to understand how fear of making poor choices was hindering me from becoming the great man who I am today. Now I am not saying I am a well-known person in any particular circle. But I am the king of my castle working hard and trying to make good decisions in regard to the paths that I have chosen. I am a great man in the eyes of my wife and my children. And that is all the recognition that I need in my lifetime. And I know that my past failures have been the building block that I continue to use to build my career and self-image in my community that I live in.

    Ben Lerer, cofounder of the CEO of Thrillist Media Group, is a good example of this. In an article on the Fast Company website, Lerer talks about this very subject. He says, “I've had to make some really tough decisions but finally, I think the best companies are those that can recognize when something isn't going right, and fix it, instead of just turning a blind eye because it's easier.” Great people make decisions. When a decision does not have the desired result, make a different decision. It does not get any simpler than that.

    Despite what so many people would love to believe, NASA hasn't discovered any evidence of past or present intelligent life on Mars. So, when the Curiosity rover (好奇号探测器）found something suspicious on the Red Planet's surface, they were not only surprised but also a little bit worried.

    The thin fragment (碎片）was suspicious enough to guarantee its own name, with NASA's Curiosity rover team calling it the “Pettegrove Point Foreign Object Debris,” named for the location where it was discovered. With no idea what it was or where it came from, the rover s handlers began to worry that it might actually be a piece of the rover itself, suggesting some unseen damage or other issue with the robot. Thankfully, those concerns seem to have been unfounded.

    In a new update from NASA the object has now been identified as a natural piece of rock rather than a piece of any man-made craft or vehicle. The team analyzed the bizarre object with a tool called the ChemCam RMI. The instrument uses a laser (激光器）t0 sniff out the makeup of anything it's pointed at, and the results for this particular piece of debris revealed that it's actually just a very thin piece of rock.

    NASA describes the inspection： The planning day began with an interesting result from the previous plan's ChemCam RMI analysis of a target that was referred to as “Pette Point Foreign Object Debris” （PPFOD),and speculated to be a piece of spacecraft debris fact was found to be a very thin flake of rock, so we can all rest easy tonight-Curi0sity n0t begun to shed its skin!

    How this particularly thin sliver of rock got to where it is—and why it seems to be a different colour than the surrounding sand and debris-remains unexplained, but at least the rover falling apart.

    Simpson is 53, "not sporty" and has suffered from asthma all her life. Two years ago her son Jay, now 10, took up BMX (自行车越野赛). "I enjoyed watching him and thought I'd like to try it," Simpson recalls. "But I didn't want to embarrass myself. I hadn't ridden for over 40 years."

    Then she noticed a session for women and girls at Burgess Park BMX Track in Peckham, south-east London, where Jay trained. This season Simpson raced at the London BMX series and finished third in her category.

    "It was the most worrying experience of my life. But it was also exhilarating," she says cheerfully. "My son is proud of me. We now share a real love for the sport. It has brought us closer together."

    Since becoming part of the Olympic Games in 2008, the popularity of BMX has risen. A program introduced in London in 2011 by the sports development charity Access Sport has seen tracks built in several London regions, backed up with investment in coaching, and the program is being rolled out to Bristol.

    Wright's children Skye, 11 and Xander, 10 are sponsored riders who have represented Great Britain in every world championship since 2014. Wright says she was motivated to start BMX herself out of an interest aroused by watching so much of it. "It's an eye-opener to share your children's interests," she explains. "You comprehend what they go through in a much more direct way. It adds another dimension to your relationship."

    It is also a high-impact sport and the risks are fairly obvious. "I totally get the fear," says Emma, 51, a BMX exercise coach and cycling instructor. "It's the fear of doing something new, of getting hurt. But I say 'Come and give it a try.' The chance of having an accident is slim, and you can spend time on the flat to improve your confidence."

The rejuvenating effects of a restorative nocturnal repose are widely recognized; it can engender a state of enhanced well-being. Academics in the field posit that the excellence of one's slumber may indeed be instrumental in the prolongation of one's lifespan.

Male subjects who enjoy a state of somnolent tranquility could potentially extend their existence by a span of nearly five decades in comparison to those bereft of such repose. The female counterparts stand to gain an increment of two decades. Additionally, it has been observed that youthful individuals who adhere to salutary somniferous routines are less susceptible to a premature demise. However, the mere quantity of repose is insufficient to reap the potential healthful dividends; the caliber of one's slumber is equally pivotal.

The parameters of commendable slumber were delineated by a quintet of distinct criteria. These encompassed an optimal duration of seven to eight hours of repose per nocturnal cycle; experiencing difficulty in the initiation of sleep no more than twice per hebdomadal period; similar challenges in maintaining somnolence no more than twice weekly; abstaining from the consumption of any soporific pharmaceuticals; and awakening with a sensation of invigoration on no fewer than five days per septenary cycle.

The conclusions derived from the study intimate that approximately 8% of fatalities, irrespective of their etiology, could be imputed to inadequate somniferous patterns. Dr. Frank Qian, a resident physician specializing in internal medicine at the Beth Israel Deaconess Medical Center in Boston, America, remarked, "A distinct proportional response relationship was discerned. Consequently, an increase in the beneficial elements pertaining to the quality of sleep correlates with a progressive diminution in mortality from all causes."

The research collated data from a populace of 172,321 individuals with an average age of 50, of which 54% were female. These participants were engaged in the National Health Interview Survey, spanning the years 2013 to 2018, which sought to scrutinize the well-being of the American populace, inclusive of inquiries into their somniferous habits.

The subjects were tracked for a mean period of 4.3 years, during which 8,681 succumbed to death. Of these fatalities, 2,610 (30%) were attributable to cardiovascular afflictions, 2,052 (24%) to oncological disorders, and 4,019 (46%) to a miscellany of other causes. Among the male and female participants who reported adherence to all five indices of quality sleep (an optimal quintile score), the expectancy of life was augmented by 4.7 years for males and by 2.4% for females, in contradistinction to those who possessed none or a solitary factor.

Further scholarly endeavor is warranted to elucidate the raison d'être for the dichotomy in the enhancement of life expectancy, with males exhibiting twice the increment observed in females despite equivalent somniferous quality.

A caveat of the study lies in the reliance on self-reported somniferous habits, which were not subjected to objective quantification or verification.
