78-year-old who has written over 175 books: My 4 'hard rules' for keeping my brain sharp and quick
I've written more than 175 books over the course of my career — on a wide range of topics, including marine biology, job interviews, ancient trees, creativity, baseball, dinosaurs, American history, resume writing, tsunamis, and Mother Goose. I also spent over three decades as a professor and worked with more than 100 schools across North America as a consultant.
Even though I'm retired now, I still write books, give presentations, and blog about psychology. My secret to staying sharp is simple: I am constantly curious.
Our brain's chemistry changes when we become curious. Curiosity is what sharpens our intellectual powers, and keeps us mentally active well into our golden years. Here are my four hard rules for keeping my brain sharp and quick:
There's a common belief that knowledge is the key to success. But growing research suggests that some of the most successful people embrace their own "innate ignorance."
They understand that there is much more to learn about the world, but they don't let that impede their progress. If anything, it galvanizes them to do more. Knowing what we don't know can be a powerful mindset shift that sparks growth and creativity.
How to do this: Once or twice a week, select a topic you know little about, preferably one unrelated to your job or background. Maybe it's WWII fighter pilots, prehistoric cave paintings, or square-trunked trees.
Spend five to 10 minutes learning all you can about that topic. Write down three interesting facts. This is a small but powerful way to exercise your brain.
Many of us get trapped in an endless cycle of convergent thinking, or always looking for the "right" answers.
But I've spent my entire career as an educator, and I can tell you that most schools trained us to focus on facts ("What is the capital of Pennsylvania?"), rather than creative answers ("Where do you think the capital Pennsylvania be located?").
Divergent questions, or open-ended questions that have multiple answers, encourage deeper thinking and help keep your mind flexible.
How to do this: A few times a week, ask yourself "What if...?" questions:
Not only are these questions fun, they can also generate a number of responses and paths for exploration.
According to researchers at the Greater Good Science Center at the University of California, Berkeley, experiencing awe can stimulate wonder and curiosity.
Some examples can be holding a newborn baby, seeing the Grand Canyon for the first time, or watching a kaleidoscope of butterflies dance over an open field. That sense of awe can improve our well-being, contribute to a more positive attitude, and boost curiosity.
How to do this: Once or twice a month, go to a place you've never been before. It doesn't have to be somewhere far — maybe a local park or new restaurant. Find something awesome, spend time observing, and record your thoughts.
Reading outside our field of expertise may be one of the most significant things we can do to develop our natural curiosity. When we expose ourselves to different ways of thinking through literature, we open up new possibilities for learning.
Even after 50 years of teaching, my current reading list includes books not on education, but on marketing strategies, paleontology, growing tomatoes, British narrowboats, island ecology, long distance running, and redwood trees, among many others.
How to do this: Visit your local public library and pick at least three books on topics that interest you, but that you've never formally studied or worked in. Read at least one chapter a day. You might be surprised by where your research takes you.

Why many women over age 52 have a higher risk of getting STIs
STIs are on the rise — but it's not just frat bros and free-lovers feeling the burn. While younger people still account for the majority of cases, studies show that some of the steepest spikes are happening in people 55 and up. Experts have offered several explanations for the surge, but research suggests there's a risk factor affecting many midlife and older women that has largely flown under the radar and could be playing a key role. Advertisement 4 More Americans are having sex in their senior years thanks to advancements in medicine. Monkey Business – More than a million American women hit menopause each year — and it's not just hot flashes and mood swings they're facing. The transition, which wraps up around age 52 on average, marks the end of reproductive years and is driven by a drop in estrogen as the ovaries slow hormone production. While vaginal dryness and loss of elasticity are well-known symptoms, research from Ohio State University (OSU) shows that menopause can also weaken the vaginal tissue itself, making it more prone to tearing. Advertisement That vulnerability comes down to changes at the cellular level. The vagina's surface is made up of multiple layers held together by key proteins like desmoglein-1 (DSG1) and desmocollin-1 (DSC1). 'These proteins strengthen the vaginal lining and restrict pathogen access to deeper tissue, reducing the risk of infection,' Dr. Thomas L. Cherpes, associate professor of otolaryngology at OSU, wrote in The Conversation. Advertisement 4 Menopause can bring a host of uncomfortable symptoms, including vaginal changes. – In their research, Cherpes and his colleagues found that postmenopausal women have significantly lower levels of DSG1 and DSC1 than women who haven't gone through the transition. To see how this might impact infection risk, the researchers removed the ovaries of mice in a lab to mimic estrogen loss in postmenopausal women. Compared to mice with intact ovaries, those without had far lower levels of DSG1 and DSC1 in their vaginal tissue. Advertisement The team also found that these mice were more vulnerable to infection with herpes simplex virus type 2 (HSV-2), which causes genital herpes. They were less able to clear chlamydia infections from the lower genital tract as well. The findings help explain why postmenopausal women are more susceptible to STIs than their younger counterparts. Notably, when Cherpes and his colleagues applied estrogen cream to the mice without ovaries, it restored the vaginal lining's integrity and fully protected them from HSV-2 infection. 4 The vaginal tissue is more vulnerable to tearing after menopause, opening the door to infection. megaflopp – 'While additional research is needed, findings from our lab suggest that estrogen-containing compounds used to relieve vaginal irritation and other symptoms of genitourinary syndrome of menopause can also reduce susceptibility to STIs among older adults,' Cherpes wrote. Sex doesn't stop — and neither do the risks Americans might not like to talk about it, but older adults are still very much having sex. A 2018 survey found nearly 40% of people aged 65 to 80 are sexually active, and almost two-thirds remain interested in sex. Advertisement More recent AARP data shows that 26% of 60- to 69-year-olds and 17% of those 70 and older have sex weekly. 'Hormone-replacement therapy, vaginal lubricants and the approval of sildenafil (Viagra) and its relatives have extended people's sex lives,' Dr. Sandra Adamson Fryhofer told the American Medical Association. But while more people are living longer and staying sexually active, more are also paying the price. 4 Sex-crazed seniors are fueling a major spike in STIs nationwide. David – Advertisement 'Rates are highest in the under 25 age group, which accounts for about 50% of STIs, but we're definitely seeing a rise in infections in the older population, particularly in people over 65,' Dr. Angelina Gangestad said in an interview with University Hospitals. Between 2010 and 2023, the number of Americans over 65 diagnosed with chlamydia, gonorrhea or syphilis rose by roughly three-, five- and sevenfold, respectively, according to the Centers for Disease Control and Prevention. Research also suggests women over 50 are at greater risk for HIV than their younger peers. Advertisement In addition to the effects of menopause, experts say several other factors are likely fueling the rise. Condom use is significantly lower among older adults compared to younger people. One study found that just 3% of Americans aged 60 and older have used a condom in the past year. Older adults also tend to have less knowledge about STIs, including how they spread, what symptoms look like and how to prevent them. Advertisement To make matters worse, research suggests that many doctors don't ask older patients about their sex lives — and seniors aren't exactly jumping to bring it up with their family or friends, either. 'No one wants to think about grandma doing this,' Matthew Lee Smith, an associate professor at the Texas A&M School of Public Health, told NBC News. 'You certainly aren't going to ask grandma if she was wearing condoms — and that's part of the problem, because every individual regardless of age has the right to intimacy.'

Strong Support for NASA and Project Artemis Will Advance the U.S.
During President Trump's first term in office, he signed Space Policy Directive 1, signaling the administration's desire to bring American astronauts back to the moon. This directive, and similar ones, later became Project Artemis, the lunar campaign with broader ambition to get the U.S. on Mars. But will we get to the moon, not to mention Mars? As the space race against China barrels forward, the White House first proposed $6 billion in total cuts to NASA funding, a roughly 24 percent reduction that experts said would be the largest single-year cut to agency funding in history. On supporting science journalism If you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today. But in the aftermath of President Trump signing the ' One Big Beautiful Bill,' which did reintegrate certain funds for Project Artemis, Congressional appropriations committees have continued to push back against the administration's myriad cuts to NASA, which for the space agency's science unit alone was a 47 percent reduction to approximately $3.9 billion. The Senate committee's bill kept NASA science funding, integral to the support of Artemis and its mission, roughly at their current levels, while the House draft halved the cuts proposed by the White House. The Senate appropriations committee also firmly rejected the president's original proposal to terminate Project Artemis's Space Launch System and Orion Spacecraft after the conclusion of the Artemis III mission. This conflict and dizzying back and forth regarding America's moonshot project suggests a question: Are we committed to Artemis and the broader goal of understanding space? Or to put it another way: Do we want to win this new race to the moon? The current administration owes us an answer. There's more than just a soft-power victory over China's taikonauts at stake. This endeavor is about cementing the U.S. as a technological superpower, a center for understanding space and our solar system, and in due course, setting us up to be the first to live and work on the moon. Americans support this goal. A recent CBS News poll shows broad support for sending astronauts back to the moon. But it will be hard for the administration to reconcile its anti-government spending message with a full-throated support of Artemis and related missions. This isn't the first time the U.S. has faced such a debate. In the winter of 1967, Senator Clinton P. Anderson and his space committee initiated an inquiry into the disastrous Apollo 1 fire that killed three American astronauts. Letters flooded into Congress. Concerned citizens across the country offered their theories about the cause of the conflagration. But others asked a more poignant question that was at the center of national debate: Why are we going to the moon in the first place? 'I want to say here and now that I think the moon project is the most terrible waste of national funds that I can imagine,' wrote James P. Smith of Cold Spring Harbor, N.Y. in a letter housed at the Legislative Archives in Washington D.C. 'Let [the Russians] go to the moon and let us use our money to end the war in Vietnam and raise our standards of living.' Others pressed their representatives to not give up their support of the Apollo program. Julius H. Cooper, Jr., of Delmar, Md., said in his letter to Anderson's committee: 'Should a manned landing by the Soviets occur on the moon first make no mistake about it the political and scientific repercussions will be tremendous.' Today's America, in many ways, is the same. Social discord, financial struggles, and conflicts abroad continue to consume our country's time, energy and resources. But the value of Project Artemis goes beyond the scientific discoveries and technological advancements that await. The success of this new moonshot will at the very least prevent space dominance from adversaries, including Russia and China, which have partnered together on their own International Lunar Research Station. Both countries have declined to sign onto the Artemis Accords, a worrying sign that these nations don't agree with our approach to the 'peaceful' exploration and use of space. To be clear, this Artemis isn't just a jobs program. Although the work created by these missions will bring a positive economic impact, the reality is that humankind's future is among the stars. Our government should be the one to orchestrate the path there while inspiring the next generation to continue exploring the depths of space. But instead of leaning into the benefits of Project Artemis, the administration is creating hurdles for the moon bound mission. To start, NASA has no permanent leadership. The administration withdrew its nomination of tech billionaire and civilian astronaut Jared Isaacman to lead the space agency, so despite the recent appointment of Secretary of Transportation Sean Duffy as interim administrator, NASA will continue for months without a leader pushing Project Artemis forward. And despite Duffy's assurance that Artemis is a critical mission, the message runs hollow if word from the Oval Office doesn't match. Again, the president initially called for the end of the program's Space Launch System and Orion crew capsule following the Artemis III mission for more cost-effective commercial systems. Trump's initial budget also called for the termination of the Gateway station, the planned lunar outpost and critical component of Project Artemis's infrastructure. This would effectively kill the program that President Trump championed with his initial space policy directive. Congress did ultimately provide funding for additional Artemis missions in the One Big Beautiful Bill Act, but it remains to be seen whether that reflects a sustained change in the administration's commitment. The success of Artemis requires extended support, not preemptively phasing out critical mission components or funding for NASA's incredibly valuable science missions. Artemis and NASA's science programs contribute an extraordinary amount toward America's technological might, so funding shouldn't be framed as an 'either/or' proposition. Now is the time to brush away uncertainty and put Artemis on a track forward. As critics have pointed out, it is unclear whether NASA has a tangible plan for getting to the moon and back. The lunar landing system is still in the concept stage. This is a chance for the president to show leadership by stepping in and pushing his government to achieve a monumental task, one that he might compare to the success of Operation Warp Speed during his first term. The administration needs to move fast and nominate a leader for NASA who will prioritize Artemis and its core mission. It needs to walk back plans to slim down government that are causing 2,000 senior officials to leave NASA at a time when leadership matters more than ever before. In short, Project Artemis requires financial certainty. The success of the program will come from the willingness of this administration to fully commit to it. In Air & Space magazine's June/July 1989 issue commemorating the 20th anniversary of the Apollo 11 moon landing, author Andy Chaikin opined on why America hadn't yet gone back. 'One of the lessons of Apollo is that the decision to 'go someplace' can't come from anyone in NASA, or from moon advocates, or from the Mars advocates,' he wrote. 'It's got to come from the top.' If President Trump supports this moonshot, Americans deserve a clear justification straight from the Oval Office. Americans need to buy into the message from the top, whether it's one of technological or political superiority, a desire to discover the unknown, or something else. Ultimately, Senator Anderson's 1967 space committee recommended that the Apollo program continue, with the caveat that improvements needed to be made. Today, boxes of letters sent into the Apollo 1 investigatory committee sit in the Center for Legislative Archives in Washington, D.C., serving as a time capsule of one of America's most contentious debates. Inside one of these boxes there's a handwritten letter from a woman named Ruth B. Harkness, of Wataga, Ill., inquiring about the U.S.'s determination to get to the moon. It distills down the very question we're struggling with now. 'May I ask, Why?' she wrote. Tell us, Mr. President.

'Eclipse of the century': Lengthy 6-minute solar eclipse is coming Aug. 2, 2027
No, the world will not go dark this weekend. Rumors about a lengthy total solar eclipse may have been circulating online, but the so-called "eclipse of the century" isn't for another two years. A total solar eclipse lasting up to 6 minutes and 23 seconds, at its peak, is expected to occur on Aug. 2, 2027, according to NASA. The total solar eclipse, in which the moon moves perfectly between the sun and Earth and casts a shadow on Earth, will be one of the longest in several decades. For a time comparison, the total solar eclipse that occured on April 8, 2024, lasted 4 minutes and 28 seconds at its peak. The solar eclipse of 1991, however, lasted 6 minutes and 53 seconds. reports the Aug. 2, 2027 eclipse will be the longest eclipse totality until 2114. The eclipse will be visible in parts of Africa, Europe and the Middle East. Unfortunately for American skywatchers, the vast majority of the U.S. won't have a view of it. The Aug. 2, 2027 solar eclipse isn't actually the next total solar eclipse though. That one, on Aug. 12, 2026, will be visible in Greenland, Iceland, Spain, Russia and parts of Portugal, according to NASA. Here's what to know about the solar eclipse on Aug. 2, 2027. The solar eclipse's path of totality will cross over parts of Africa, Europe and the Middle East, according to National Eclipse and NASA. Parts of the following countries are within the path of totality. Other countries in Africa, Europe and the Middle East will have a partial view of the eclipse. A partial solar eclipse will be visible in parts of Maine between 5:14 and 5:19 a.m. ET on Aug. 2, 2027, according to Time and Date.
