American College of Physicians 'stepped out of its lane" by placing gun control in medical education. Stanley Gold-farb, formerly the associate dean of curriculum at the University of Pennsylvania's Perelman School of Medicine, argued that teaching social justice issues and population health comes "at the expense of strict training in medical science" at a time when sub-specialists are in short supply. But many physicians, ourselves included, think social issues should be at the heart of medical education.
Formal medical school typically takes four years, followed by several years of residency(住院医生实习期)and often a fellowship(研究员职位), and during that short time students have a wide range of competing requirements. They must learn complex biological and chemical pathways that explain diseases and health. They must be educated on how to read the the scientific literature and apply it to their patients. They must master many therapies and know how to adapt them to patients' varied diseases states. On top of all this, they must learn to communicate effectively and compassionately with patients and colleagues.
Being a good doctor also demands that we understand the reasons behind poor health. Our mission is not simply to diagnose, manage and treat. Physicians should act to prevent the root causes of illness and improve well-being. Physicians are trained to tackle problems at their root. System and structural-level social issues are also drivers of poor health, and it is our duty to address them. Medical training must evolve to produce doctors who are able to not only treat the individual but also understand the larger influencers of health -- of which gun violence is most emphatically one. As medical professors, we would fail our students -- and our patients - if we expected any less.

Finding Comfort in War and Peace
Over the past 15 years, Yiyun Li, a Chinese-American author, has read War and Peace at least a dozen times. Her hardback copy of Leo Tolstoy's 1,200 - page saga bristles with colored notes, like some exotic lizard's spine. The novel is not just a masterclass in fiction, Ms. Li believes, but a cure for

The Paint Creek Recreation Trail is the flagship pathway of a planned trail network in the Ohio counties of Fayette, Ross and Highland. Nearly 35 miles of paved trail are currently open linking the communities of Washington Court House, Frankfort and Chillicothe.
The vast majority of the trail occupies a former railroad corridor acquired by the local nonprofit trails group in 1994. However, the trail does leave the original corridor where the right-of-way could not be acquired from its current owners. The diversions are usually short, with the longest stretch being a 2.5 mile stretch of highway cast of the Washington courthouse.
Because most of the trails through rural Ohio are dominated by seemingly endless fields, trail users are exposed to the sun for long periods of time. Fortunately, the path occasionally winds through a more wooded corridor near local waterways, such as Paint Creek and the Scioto River.
The Paint Creek Recreation Trail also passes through the downtown areas of the three towns along the way, offering many opportunities for rest and energy. Just before Chillicothe, trail users will want to stop at Hopewell Culture National Historical Park. The Hopewell Mound Group, a part of the park visible from the trail along Sulphur Lick Road, features earthworks and tombs built by the local people nearly 2,000 years ago.
The existing Paint Creek Recreation Trail will one day make a significant contribution to local leisure and transportation. There are plans nowadays to develop new trails along former railroad corridors from Washington courthouse northwest to the existing Xenia-Jamestown Connector, southwest to Wilmington and cast to Circleville in Pickaway County.

5 . Are we just thinking with our heads? No. The human brain is just like a telephone switchboard (总机), but not a whole system. Its function is to receive incoming signals, establish appropriate connections, and send the information to its destination. In order to provide efficient service, the body must function as a whole.
But where is the mind? Is it in the brain? Or the nervous system? Can we say that the mind is in a particular place? In fact, the mind is not a thing, not a leg, and not even a brain. Thinking is both a function and an activity. Aristotle, 2300 years ago, noted that the mind is to the body what the tool is to the worker. When the tool is not in use, there is no work. Charles Woolbert said that consciousness is what the body does.
If this activity is necessary for thought, it is also necessary for the transmission of thought from one person to another. Observe how people conduct their daily conversations. If you've never taken the trouble to do this, you'll have a surprise waiting for you, because good conversationalists are almost always in motion. Their heads nodded and nodded, sometimes so violently that you wondered how their necks could withstand the strain. Even the legs and feet are active. As for hands and arms, they rarely stay still for more than a few seconds at a time.
Remember, these people are not giving speeches. They're just people, trying to get their points of view across. They have no sense of movement. Their language has not been studied. They're just human beings in a human environment, trying to adapt to the social environment. However, their conversation is not only verbal, but also visual, involving almost every muscle in the body. Briefly, because people are really thinking, the speaker must be everywhere if he is to succeed in getting people to think.
