From a Wall Street Journal online article:
Dementia is a complicated disease that has multiple causes and risk factors, some of which remain unknown. Nevertheless, there is increasing evidence that people—even those who inherit genes that put them at greater risk of developing Alzheimer’s in later life—can improve their chances by adopting lifestyle changes.
“It’s not just about running three times a week,” says Sarah Lenz Lock, executive director of AARP’s Global Council on Brain Health. “Instead, it’s about a package of behaviors, including aerobic exercise, strength training, a healthy diet, sleep and cognitive training.”
When it comes to battling dementia, the unfortunate news is this: Medications have proven ineffective at curing or stopping the disease and its most common form, Alzheimer’s disease. But that isn’t the end of the story. According to a recent wave of scientific studies, we have more control over our cognitive health than is commonly known. We just have to take certain steps—ideally, early and often—to live a healthier lifestyle.
In fact, according to a recent report commissioned by the Lancet, a medical journal, around 35% of dementia cases might be prevented if people do things including exercising and engaging in cognitively stimulating activities. “When people ask me how to prevent dementia, they often want a simple answer, such as vitamins, dietary supplements or the latest hyped idea,” says Eric Larson, a physician at Kaiser Permanente in Seattle and one of a group of scientists who helped prepare the report. “I tell them they can take many common-sense actions that promote health throughout life.”

From Helen of Troy’s abduction to the deception of the Trojan Horse and the fall of the city, tread the line between myth and reality in this phenomenal new exhibition.
The story of the ancient city of Troy, and of the great war that was fought over it, has been told for some 3,000 years. Spread by travelling storytellers, it was cast into powerful words by the Greek poet Homer as early as the eighth to seventh century BC – and into powerful images by ancient Greek and Roman artists. Just as it enraptured audiences in the past, it still speaks to us today and it’s easy to see why. It’s a story that has it all – love and loss, courage and passion, violence and vengeance, triumph and tragedy – on a truly epic scale.
Expect many of those chairs to be filled in the months ahead. The Winter Village is a huge draw, built around a massive ice rink enjoyed by upwards of 300,000 skaters throughout the holiday season. “We want people to enjoy great cocktails and drinks at the Porch, to take time to relax and appreciate the city with all its extraordinary energy,”

Right now, you tend to have investment advisors for retirees, and insurance advisors or salespersons for retirees, and it’s fairly rare to go to somebody who can sell you annuities or invest your money and has no financial incentive to tilt one way or the other. Ultimately, what I’d like to see are people who have knowledge of both annuities and investments, and who are compensated in a way that doesn’t influence the decision.
Nobel Prize–winning economist William Sharpe has spent most of his career thinking about risk. He’s behind the Capital Asset Pricing Model for gauging systemic risk and the eponymous Sharpe ratio, which captures risk-adjusted return.
Syndicated columnist Mark Shields and New York Times columnist David Brooks join Judy Woodruff to discuss the week in politics, including whether public impeachment hearings are making President Trump more or less vulnerable, what stood out about the witnesses who testified so far, whether Trump’s Ukraine dealings are surprising or “in character” and the latest dynamics among 2020 Democrats.
