For a Healthy Brain, Play the Long Game
Nothing keeps the mind healthy like an education, say psychologists. And contrary to past belief, recent research shows that new neural connections can be built well into middle age.
What's the Latest Development?
Psychologists are learning that the brain stays agile well into middle age, retaining the ability to learn new skill sets and take on different points of view by building new neural connections. And nothing is more important to maintaining a healthy brain than receiving an education, say psychologists. Up to age 75, mental tests demonstrate that 'people with college degrees performed on complex tasks like less-educated individuals who were 10 years younger.' In other words, learning keeps you young.
What's the Big Idea?
A greater understanding of intelligence has come to light in recent years which distinguishes between what psychologists refer to as fluid and crystallized intelligences. While fluid intelligence—memory and abstract thinking—peaks in your 20s, crystallized intelligence—inductive reasoning and judgement—continues to build until very late in life. Perhaps most encouraging of all is that the brain remains 'fluid' until much later than was previously thought, retaining the ability to forge new neural connections through new experiences.

Since the idea of locality is dead, space itself may not be an aloof vacuum: Something welds things together, even at great distances.
- Realists believe that there is an exactly understandable way the world is — one that describes processes independent of our intervention. Anti-realists, however, believe realism is too ambitious — too hard. They believe we pragmatically describe our interactions with nature — not truths that are independent of us.
- In nature, properties of Particle B may be depend on what we choose to measure or manipulate with Particle A, even at great distances.
- In quantum mechanics, there is no explanation for this. "It just comes out that way," says Smolin. Realists struggle with this because it would imply certain things can travel faster than light, which still seems improbable.
E-cigarettes may be safer than traditional cigarettes, but they come with their own risks.
- A new study used an MRI machine to examine how vaping e-cigarettes affects users' cardiovascular systems immediately after inhalation.
- The results showed that vaping causes impaired circulation, stiffer arteries and less oxygen in their blood.
- The new study adds to a growing body of research showing that e-cigarettes – while likely safer than traditional cigarettes – are far from harmless.
