Light dappled through the trees in the family courtyard, painting shadows on the paving stones. Li Reiko knelt by her son to look at his scraped knee. "I just scratched it." Nawi squirmed under her hands. Her daughter, Aya, leaned over her shoulder studying the healing. "Maybe Mama will show you her armor after she heals you." Nawi stopped wiggling. "Really?" Reiko shot Aya a warning look, but her little boy's dark eyes shone with excitement. Reiko smiled. "Really." What did tradition matter? "Now let me heal your knee." She laid her hand on the shallow wound. "Ow." "Shush." Reiko closed her eyes and rose in the dark space within her mind. In her mind's eye, Reiko took her time with the ritual, knowing it took less time than it appeared. In a heartbeat, green fire flared out to the walls of her mind. She dissolved into it as she focused on healing her son. When the wound closed beneath her hand, she sank to the surface of her mind. "There." She tousled Nawi's hair. "That wasn't bad, was it?" "It tickled." He wrinkled his nose. "Will you show me your armor now?" She sighed. She should not encourage his interest in the martial arts. His work would be with the histories that men kept, and yet... "Watch." Pulling the smooth black surface out of the ether, she manifested her armor. It sheathed her like silence in the night. Aya watched with obvious anticipation for the day when she earned her own armor. Nawi's face, full of sharp yearning for something he would never have, cut Reiko's heart like a new blade. "Can I see your sword?" She let her armor vanish back into thought. "No." Reiko brushed his hair from his eyes. "It's my turn to hide, right?" Why can't Nawi never get his armor? Pick the correct answer from the following options: - He is physically ill - not enough information - He is banned because of something he did - Men are not allowed to have armor
**Answer**

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... Who probably performed the research on the elderly that was published in JAMA? Pick the correct answer from the following options: - probably exercise physiologists and healthcare providers - probably teachers - not enough information - probably engineers

Weight gain is a complex issue. But there is little doubt that the current food environment in Western countries – heavy in highly processed salty, sugary, and fatty food – has a big role to play. Most of the salt eaten in our diet has been added to food in the manufacturing process. This is in contrast to the small amount of salt naturally present in most foods or what is added at the table or at home in cooking. Salt can be a desirable taste, increasing the palatability of foods in addition to helping preserve it; that’s why it is commonly added in processed foods. Combining salt and fat together is thought to be a potent combination in helping to promote passive over-consumption foods. Just think of how moreish salty chips can be. Having a greater liking for salty and fatty foods is associated with eating more kilojoules overall, uncontrolled eating, and overweight in children. This link between overconsumption of food and its degree of saltiness is considered stronger than having a liking for sweet and fatty foods. Teasing out further how salt may influence the over-consumption of fatty foods, sensory researchers from Deakin University recruited 48 healthy adults to take part in a tasting panel. Over four lunchtime sessions (following on from a standardised breakfast that morning), each person ate a meal of macaroni and cheese where the fat and salt content had been manipulated. The four meal combinations were low-fat/low-salt, low-fat/high-salt, high-fat/low-salt and high-fat/high-salt. Participants were encouraged to eat as much as they wished until feeling full. Eating rate, meal agreeability, and subjective ratings of hunger and fullness were also taken. Salt promotes over-eating Eleven percent more kilojoules were consumed when the meals eaten were high in salt. And this was irrespective of if the fat content was high or low. The fat content of the meal didn’t result in people eating more food by weight, but because of its greater energy density, that meant more kilojoules were eaten. After eating foods high in salt most of their lives, how are people most likely to be (statistically speaking): Pick the correct answer from the following options: - Fans of macaroni and cheese. - Overweight or obese. - not enough information - University researchers.
**Answer**

Overweight or obese.
