Question: 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... What does the journal author of JAMA probably think about healthy lifestyles in the elderly?  A. JAMA's author is supportive of healthy lifestyles  B. JAMA's author thinks the elderly shouldn't get involved in exercise as it is dangerous  C. JAMA's author thinks elderly should be allowed to rest  D. not enough information

The leading U.S. presidential hopefuls reacted strongly Monday to the massacre at a gay nightclub in Orlando, Florida. Sunday's incident that left 49 people dead and 53 others wounded was the worst mass shooting in U.S. history. The gunman, Omar Mateen, was a U.S. citizen and the son of Afghan parents. In her first speech since the shooting, presumptive Democratic presidential nominee Hillary Clinton told supporters in Cleveland, "The Orlando terrorist may be dead, but the virus that poisoned his mind remains very much alive." Clinton laid out a multi-faceted approach to combating terrorism. The plan would disrupt terrorist groups by infiltrating their online networks, enhancing intelligence sharing among local and federal law enforcement agencies, and asking allied nations to help "prevent the radicalization and recruitment" of potential terrorists in the U.S. and Europe. In an apparent response to presumptive Republican Party opponent Donald Trump's charge that President Barack Obama and other Democrats refuse to use the word "radical" to describe terrorists who happen to be Muslim, Clinton said earlier on CNN that she is not afraid to use the term, but says she refuses "to demonize and demagogue and declare war on an entire religion." Doing so, she said, "plays right into the ISIS' hands." ISIS is an acronym for Islamic State, which is also known as IS, ISIL and Daesh. Clinton called for citizens to reach out to Muslims in the United States "to help us defeat this threat." She cited the need for "common sense reform" of gun ownership laws, including a ban on assault weapons. After Obama did not use the term "radical" in his remarks Sunday from the White House, Trump criticized Obama's approach to extremism and said the president "should step down." Trump, meanwhile, renewed a call for a ban on the entry of Muslim immigrants into the United States. "The only reason the killer was in America in the first place was we allowed his family to come here," Trump said in a speech to supporters in Manchester, New... how does trump probably think about Muslims  A. he thinks they are terrorists  B. he thinks they are scammers  C. he thinks they are  good people  D. not enough information

Ques:As U.S. political candidates make their final appeals, voters in 35 states will decide policy issues Tuesday that include legalizing recreational use of marijuana and restricting access to guns and ammunition, voting yes or no on nearly 160 state ballot initiatives. California's Proposition 64, which is leading in the polls, could create a multibillion-dollar marijuana industry by legalizing the recreational use the drug for adults in the state. Similar measures are on the ballot in Arizona, Nevada, Maine and Massachusetts. Marijuana could be legalized for medical use in Florida and three other states. Medical marijuana is already permitted in half the 50 U.S. states, and recreational use is allowed in Alaska, Colorado, Washington state, Oregon and the District of Columbia. Marijuana is banned under federal law, but U.S. officials have taken a hands-off approach on the issue. Voters in Maine and Nevada are considering measures that would expand background checks for gun purchases, which is already required for buying guns from dealers, by extending the provision to private sales. Californians will consider measures requiring background checks for buyers of ammunition and banning high-capacity ammunition magazines. Washington state has a measure that would allow the courts to bar the sale of guns to individuals deemed an extreme risk to themselves or others. Californians are considering whether to eliminate the death penalty with Proposition 62, or to maintain capital punishment and make the process more efficient with Proposition 66, which supporters say makes it more fair to victims of violent crimes. Twenty states and the District of Columbia have abolished or overturned capital punishment on the grounds that it is unequally applied to minority populations and that innocent people are sometimes convicted. South Dakotans will decide whether to make statewide offices nonpartisan and create a citizens commission to redraw voting districts after each 10-year national census, removing the task from legislators,... Who will create a commitee to remake districts?  A. Californians  B. political candidates  C. South Dakota voters  D. not enough information
