Surprisingly, the answer to this isnt as simple as being a morning or a night person. New research has shown that certain times of the day are best for completing specific tasks, and listening to your bodys natural clock may help you to accomplish more in 24 hours. Science suggests that the best time for our natural peak productivity is late morning. Our body temperatures start to rise just before we wake up in the morning and continue to increase through midday, Steve Kay, a professor of molecular and computational biology at the University of Southern California toldThe Wall Street Journal. This gradual increase in body temperature means that our working memory, alertness, and concentration also gradually improve, peaking at about mid morning. Our alertness tends to dip after this point, but one study suggested that midday fatigue may actually boost our creative abilities. For a 2011 study, 428 students were asked to solve a series of two types of problems, requiring either analytical or novel thinking. Results showed that their performance on the second type was best at non-peak times of day when they were tired. As for the age where our brains are at peak condition, science has long held that fluid intelligence, or the ability to think quickly and recall information, peaks at around age 20. However, a 2015 study revealed that peak brain age is far more complicated than previously believed and concluded that there are about 30 subsets of intelligence, all of which peak at different ages for different people. For example, the study found that raw speed in processing information appears to peak around age 18 or 19, then immediately starts to decline, but short-term memory continues to improve until around age 25, and then begins to drop around age 35,Medical Xpressreported. The ability to evaluate other peoples emotional states peaked much later, in the 40s or 50s. In addition, the study suggested that out our vocabulary may peak as late as our 60ss or 70s. Still, while working according to your bodys natural clock may sound helpful, its important to remember that these times may differ from person to person. On average, people can be divided into two distinct groups: morning people tend to wake up and go to sleep earlier and to be most productive early in the day. Evening people tend to wake up later, start more slowly and peak in the evening. If being a morning or evening person has been working for you the majority of your life, it may be best to not fix whats not broken. (Dana Dovey. www.medicaldaily.com, 08.08.2016. Adaptado.) According to the first and second paragraphs, the brain performance peaks in late morning because

When it comes to politics and fake news, facts arent enough The myth that vaccines cause autism has persisted, even though the facts paint an entirely different story. In todays political climate, it sometimes feels like wecant even agree on basic facts. We bombard each other with statistics and figures, hoping that more data will make a difference. A progressive person might show you the sameclimate change graphs over and over while a conservative person might point to the trillions of dollars of growing national debt. Were left wondering, Why cant they just see? Its so obvious! Certain myths are so pervasive that no matter how many experts disprove them, they only seem to grow in popularity. Theres no shortage of serious studies showing no link between autism and vaccines, for example, but these are no match for an emotional appeal to parents worried for theiryoung children. Tali Sharot, a cognitive neuroscientist at University College London, studies how our minds work and how we process new information. In her upcoming book, The Influential Mind,she explores why we ignore facts and how we can get people to actually listen to the truth. Tali shows that were open to new information but only if it confirms our existing beliefs. We find ways to ignore facts that challenge our ideals. And as neuroscientist Bahador Bahrami and colleagues have found, we weigh all opinions as equally valid, regardless of expertise. So, having the data on your side is not always enough. For better or for worse, Sharot says, emotions may be the key to changing minds. (Shankar Vedantam. www.npr.org. Adaptado.) De acordo com o texto, as pessoas
