How to Keep Your Brain Young
Rather than trying to cope with or counteract the cognitive decline that comes naturally with age, neuroscientists say that continuing to live an active and engaged life is the best strategy.
What's the Latest Development?
When it comes to maintaining a healthy brain into old age, what you do in your later years is more important than how you lived your youth, according to new scientific evidence just published in Trends in Cognitive Science. "Engagement is the secret to success. Those who are socially, mentally and physically stimulated reliably show greater cognitive performance with a brain that appears younger than its years." The cognitive advantage of highly educated individuals as well as those with especially demanding jobs rarely outlast their own retirement, say aging experts.
What's the Big Idea?
New information on how the brain ages represent a fundamental shift in how scientists advise the public to keep their brain in good working order, even as the years accumulate. Rather than trying to cope with or compensate for the cognitive decline that comes with aging, it is better to avoid those age-related brain changes in the first place. Neuroscientist Lars Nyberg points out that memory decline occurs later than most people realize, typically after the age of 60. And aging people continue to accumulate knowledge until even later in life. According to Nyberg, the latest science increasingly supports the idea of brain maintenance.

Antimicrobial resistance is growing worldwide, rendering many "work horse" medicines ineffective. Without intervention, drug-resistant pathogens could lead to millions of deaths by 2050. Thankfully, companies like Pfizer are taking action.
- Antimicrobial-resistant pathogens are one of the largest threats to global health today.
- As we get older, our immune systems age, increasing our risk of life threatening infections. Without reliable antibiotics, life expectancy could decline for the first time in modern history.
- If antibiotics become ineffective, common infections could result in hospitalization or even death. Life-saving interventions like cancer treatments and organ transplantation would become more difficult, more often resulting in death. Routine procedures would become hard to perform.
- Without intervention, resistant pathogens could result in 10 million annual deaths by 2050.
- By taking a multi-faceted approach—inclusive of adherence to good stewardship, surveillance and responsible manufacturing practices, as well as an emphasis on prevention and treatment—companies like Pfizer are fighting to help curb the spread.
No, the Syrian civil war is not over. But it might be soon. Time for a recap
- The War in Syria has dropped off the radar, but it's not over (yet)
- This 1-minute video shows how the fronts have moved – and stabilised – over the past 22 months
- Watching this video may leave you both better informed, and slightly queasy: does war need a generic rock soundtrack?
Sarco assisted suicide pods come in three different styles, and allow you to die quickly and painlessly. They're even quite beautiful to look at.
Death: it happens to everyone (except, apparently, Keanu Reeves). But while the impoverished and lower-class people of the world die in the same ol' ways—cancer, heart disease, and so forth—the upper classes can choose hip and cool new ways to die. Now, there's an assisted-suicide pod so chic and so stylin' that peeps (young people still say peeps, right?) are calling it the "Tesla" of death... it's called... the Sarco!
Entrepreneur and author Andrew Horn shares his rules for becoming an assured conversationalist.
