Have you ever wondered whether it's worth your while to encourage an older person to start exercising? In 2014, the top-notch journal JAMA published the results of a fantastic research project: a study in which 1635 sedentary older adults (aged 70-89) were assigned to get either a structured exercise program, or a program of "successful aging" health education. The researchers called it the Lifestyle Interventions and Independence for Elders (LIFE) study. (You can read the full study here.) During the LIFE study, the two groups were followed for a little over 2.5 years. And by the end of the study, guess which group of volunteers was more likely to still walk a quarter of a mile (without a walker)? That's right. When it came to avoiding "major mobility disability" which the researchers defined as becoming unable to walk 400 meters or more a structured exercise program was better than a program of healthy aging education. Specifically, the researchers found that 30% of the exercisers experienced a period of major disability, compared to 35.5% of the seniors enrolled in the healthy aging education program. This is a very encouraging finding! That said, it's also a bit sobering to realize that even with exercise, almost 1 in 3 older adults experienced a period of limited mobility, of which half lasted 6 months or more. In this post, I'll share some more details on this study, because the results provide a wonderful wealth of information that can be helpful to older adults, family caregivers, and even geriatricians such as myself. Want to know how often the exercisers experienced "adverse events"? (Hint: often!) Wondering just what the structured exercise program involved? (Hint: more than walking!) Let's dig into the details! At the end of this post, I'll share my list of key take-home points for older adults and family caregivers. Who were the study volunteers? Whenever you read about a research study, it's important to understand how the study volunteers compare to the older adults in *your* life. One of... How long did the elderly probably exercise each day in the structured exercise program published in JAMA? - Probably 30 to 60 minutes a day - Probably 6 hours a day - probably 4 hours a day - not enough information
Probably 30 to 60 minutes a day

SEOUL This week's summit between North Korean leader Kim Jong Un and South Korean President Moon Jae-in, to be held on Friday, April 27, is expected to produce a denuclearization framework that U.S. President Donald Trump could support when he meets with Kim in May or June. The North's reassuring outreach of late, including its decision to unilaterally suspend all nuclear and missile tests, has set an optimistic tone that a deal can be reached. But it is still unclear if real progress toward peace can be achieved. There have been two past inter-Korean Summits in 2000 and 2007, both held in the North. The first produced a joint peace declaration promoting humanitarian exchanges and economic cooperation. From the second came support for a permanent peace treaty and a U.S. and China-led deal to end Pyongyang's nuclear weapons program for economic assistance and security guarantees. However, North Korea's continued nuclear development efforts and missile tests, in violation of past agreements, and other hostile acts, including a alleged deadly attack on a South Korean naval ship in 2010, brought an end to any progress made at these summits. Leading up to this week's inter-Korean summit, there are encouraging developments that a nuclear deal may again be within reach. U.S. President Donald Trump's maximum pressure campaign, that led efforts to impose harsh international sanctions ending most North Korean exports, are exerting increasing economic pain that could be pressuring the leadership in Pyongyang to actually give up its nuclear arsenal this time. "If the situation continues, the foreign exchange could be depleted and North Korea can face a very serious situation at the end of this year. This is one of the reasons why it has come out in favor of dialogue," said Cheong Seong-Chang, a senior North Korea analyst at the Sejong Institute in South Korea. North Korean leader Kim Jong Un has made a number of concessions already by agreeing to talk about denuclearization without conditions, by appearing to drop past... What does Kim Jung Un really want? - he wants to go to war with the US - he wants to lie and cheat the US and Donald Trump - not enough information - he probably wants to make some kind of a deal with the US
(Answer)
he probably wants to make some kind of a deal with the US

Ques:Kadin loved the desert. Many creatures lived in the desert. Some learned to survive within her harsh burning grip. Some even learned to thrive in her, building stone monuments to themselves and living their lives surrounded in the lavish luxuries of Gods. How puny their monuments were compared to the desert herself. Where they had castles surrounded by dry moats, the desert had mountains surrounded by thousand year sandstorms. Where they had silks and the most beautiful slaves serving their every greatest desire, she had dunes that stretched for a thousand leagues and a sun that burned huge and deep crimson in the violet sky. Where desert kings, the Danken, dined on the finest food and drank the finest wine, the desert drank every drop of water from the air itself and feasted on men. Kadin knew the desert. He knew her voice whispering in the dark of night like a dangerous lover. The sound he heard now was not her voice but a cry from one trapped within the desert's teeth. It was the cry of a woman. Kadin rose from his makeshift bed in the dip of two dunes. He stood quickly, tying the leather straps of his knife belt around his waist. He pulled on his boots and silently mounted White Ash. THe mare felt his soft touch and made no sound. Kadin listened and heard the cry again. He studied the dunes in the darkness of night. THe blood moon painted the desert a deep red. He felt the echos and turned White Ash towards their origin. He rode quietly into the night. Kadin saw the glow of torchlight long before cresting the hill. He guessed four riders from the sound of their horses and confirmed it when he rose above them. Three men, now on foot, chased a woman in black across the dune. Their horses stood back, panting from a hard ride. The woman's own stallion lay dead, a black arrow buried in its flank. Why did Kadin mount White Ash? - To exercise the horse. - To ride toward the sounds of a woman's distress. - To ride to a Danken's castle - not enough information

Ans:
To ride toward the sounds of a woman's distress.
