Our risk of cancer rises dramatically as we age. So it makes sense that the elderly should be routinely screened for new tumors — or doesn't it?

    While such vigilant(警觉的) tracking of cancer is a good thing in general, researchers are increasingly questioning whether all of this testing is necessary for the elderly. With the percentage of people over age 65 expected to nearly double by 2050, it's important to weigh the health benefits of screening against the risks and costs of routine testing.

    In many cases, screening can lead to additional biopsies(活检) and surgeries to remove cancer, which can cause side effects, while the cancers themselves may be slow-growing and may not pose serious health problems in patients' remaining years. But the message that everyone must screen for cancer has become so ingrained(根深蒂固的) that when health care experts recommended that women under 50 and over 74 stop screening for breast cancer, it caused a riotous reaction among doctors, patients and advocacy groups.

    It's hard to uproot deeply held beliefs about cancer screening with scientific data. Certainly, there are people over age 75 who have had cancers detected by routine screening, and gained several extra years of life because of treatment. And clearly, people over age 75 who have other risk factors for cancer, such as a family history or prior personal experience with the disease, should continue to get screened regularly. But for the remainder, the risk of cancer, while increased at the end of life, must be balanced with other factors like remaining life expectancy(预期寿命).

    A recent study suggests that doctors start to make more objective decisions about who will truly benefit from screening—especially considering the explosion of the elderly that will soon swell our population.

    It's not an easy calculation to make, but one that make sense for the whole patient. Dr. Otis Brawley said, “Many doctors are ordering these tests purely to cover themselves. We need to think about the rational(合理的) use of health care and stop talking about the rationing of health care.”

    That means making some difficult decisions with elderly patients, and going against the misguided belief that when it comes to health care, more is always better.

    Poet William Stafford once said that we are defined more by the detours (绕行路) in life than by the narrow road toward goals. I like this image. But it was quite by accident that I discovered the deep meaning of his words.

For years we made the long drive from our home in Seattle to my parents' home in Boise in nine hours. We traveled the way most people do: the fastest, shortest, easiest road, especially when I was alone with four noisy, restless kids who hate confinement (限制) and have strong opinions about everything.

    Road trips felt risky, so I would drive fast, stopping only when I had to. We would stick to the freeways and arrive tired.

    But then Banner, our lamb was born. He was rejected by his mama days before our planned trip to Boise. I had two choices: leave Banner with my husband, or take him with me. My husband made the decision for me.

    That is how I found myself on the road with four kids, a baby lamb and nothing but my everlasting optimism to see me through. We took the country roads out of necessity. We had to stop every hour, let Banner shake out his legs and feed him. The kids chased him and one another. They'd get back in the car breathless and energized, smelling fresh from the cold air.

    We explored side roads, catching grasshoppers in waist-high grass. Even if we simply looked out of the car windows at baby pigs following their mother, or fish leaping out of the water, it was better than the best ride down the freeway. Here was life. And new horizons (见识).

    We eventually arrived at my parents' doorstep astonishingly fresh and full of stories.

    I grew brave with the trip back home and creative with my disciplining technique. On an empty section of road, everyone started quarreling. I stopped the car, ordered all kids out and told them to meet me up ahead. I parked my car half a mile away and read my book in sweet silence.

    Some road trips are by necessity fast and straight. But that trip with Banner opened our eyes to a world available to anyone adventurous enough to wander around and made me realize that a detour may uncover the best part of a journey—and the best part of yourself.

    How's your happiness quotient (指数)? Science tells us that if you want to increase your "happiness quotient" every day, it's important to take time and accept the present blessings (恩赐) in your life.

    I wanted to share a moment of feeling about some of my blessings and what's in my life to be grateful for as Thanksgiving approaches.

    One of our family traditions at our Thanksgiving meal is to go around the table and to let each one share something we're especially thankful for.

    I'm going to recite lots of things, including that I'm grateful for my health, my loving husband, and the wonderful relationship we share. My husband joins me for 3-mile walk to start our day. The exercise habit keeps our moods in check and the ups and downs of life easier to manage. We talk as we walk, sharing ideas, worries and good feelings too. Sometimes we argue a little until we figure out what to do. We always come up with something. What a blessing that is!

    It is so much to be grateful for. I feel I am the luckiest woman alive. It's my wish for you that you'll be able to spot something in your life. I hope yet you will savor (体味) and appreciate it.

    Many of us spend the holiday with our aging parents or other loved ones. In my work at AgthgParents.com, we just reminded everyone that you never know if there will be another Thanksgiving with these loved ones. We can't take the day for granted. Just be in the moment. We suggest that you verbally give thanks to your parents, no matter what conditions your aging parents may be in now. Do what you can to be tuned in to what you need as well as what your family needs.

    E-Sports, short for electronic sports, is one of the growing industries in the world, with prizes totaling around $25 million up for grabs in some tournaments. E-Sports are professional multiplayer video game competitions. Any video game with a strong competitive element is considered e-Sports. The competition models itself after traditional professional sports in several ways: it uses corresponding tournament formats, involves player contracts, and is governed by regulations. The athletes who compete in e-Sports competitions are gamers．

    The history of e-Sports dates back to 1972 when some Stanford University students competed in the Intergalactic Space War Olympics for the opportunity to win a one-year subscription to the Rolling Stone Magazine. E-Sports pretty much continued on the rather quiet path until the 80s when competitions like the Space Invaders Championship shot them to the spotlight. 2002 marked the beginning of a new era for the sport and laid the foundation for what e-Sports would become thanks to the release of the Xbox live, which brought online play to consoles. Halo Ⅱ became the first game to be shown on national television for Major League Gaming in 2004, paving the way for e-Sports to become a global phenomenon.

    Today, e-Sports are growing at a rapid pace thanks to advance in technology and the arrival of streaming services like Twitch which have exposed video game competitions to a new audience due to their extensive reach.

    To understand how much impact Twitch has made, data from gaming analyst group Newzoo show that e-Sports global audience increased 43 percent from 204 million to 292 million between 2014 and 2016. Interestingly, this coincides (一致) with Amazon's acquisition of Twitch in 2014 and its effort to make the competition a spectator sport.

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.
