Researchers from Israel reversed two key processes involved in aging.
- Israeli scientists reversed two major processes involved in aging.
- Their new therapy counteracted the shortening of telomeres and the accumulation of old and dying cells.
- The study participants underwent oxygen treatments in hyperbaric chambers.

Research suggests that aging affects a brain circuit critical for learning and decision-making.
As people age, they often lose their motivation to learn new things or engage in everyday activities. In a study of mice, MIT neuroscientists have now identified a brain circuit that is critical for maintaining this kind of motivation.

- A new study found that weekly 15-minute "awe walks" have positive effects on mental health.
- Volunteers reported higher levels of gratitude and compassion after eight weeks of these short walks.
- Researchers believe this low-cost intervention could help prevent cognitive decline in older adults.
Finding Happiness Through "Awe Walks"<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="0988a4421b47d7cdc45d740014a53b17"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/-nVx6SriWPM?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Importantly, participants were instructed to observe details while walking around the forest. If the goal was only exercise, volunteers were likely to power through trails without noticing their surroundings. This is where awe comes into the picture.</p><p>UC Berkeley psychologist Dacher Keltner <a href="https://www.ucsf.edu/news/2020/09/418551/awe-walks-boost-emotional-well-being" target="_blank">explains</a> the relevance, noting that feelings of awe help us feel more generous and humble, while increasing our overall well-being. </p><p style="margin-left: 20px;">"Awe is a positive emotion triggered by awareness of something vastly larger than the self and not immediately understandable — such as nature, art, music, or being caught up in a collective act such as a ceremony, concert or political march."</p><p>The post-walk selfie is key. Week after week, their smiles grew larger. Incredibly, their bodies shrunk in the photos—the photographer stepped back to include more of nature. Instead of the normal close-ups we associate with selfies, volunteers naturally became more integrated with their environment, without any prompting from the research team.</p><p><a href="https://bigthink.com/21st-century-spirituality/individualism-is-spreading-and-thats-not-good" target="_self">Research</a> on individualist versus collectivist societies shows that the members of individualist societies tend to prioritize independence and autonomy. These seem like positive qualities, though higher rates of anxiety and depression are reported in such cultures. By contrast, collectivist societies emphasize interdependence, which ultimately makes members feel like they're part of a bigger landscape. </p><p>This is exactly what was reflected in those selfies. </p>

People only appear as part of a much larger scene. This trend cuts across Buddhist art, perhaps unsurprisingly given the philosophy stresses collectivity. Happiness levels tend to be higher in these societies than in individualist nations.</p><p>America, arguably the global leader in individualism, has <a href="https://worldhappiness.report/ed/2019/the-sad-state-of-happiness-in-the-united-states-and-the-role-of-digital-media/" target="_blank">continually ranked lower</a> on world happiness charts over the last 40 years. Meanwhile, our rates of Alzheimer's disease <a href="https://bigthink.com/mind-brain/alzheimers-risks" target="_self">rise</a> every year.</p><p>Can a 15-minute awe walk change all of that? Not completely, but we'll take whatever help we can get. As mythologist Joseph Campbell <a href="https://www.jcf.org/works/quote/awe-is-what-moves-us-forward/" target="_blank">once remarked</a>, "awe is what moves us forward." He cited awe as a primary driver in the creation of mythology: the overwhelming sensation that you're part of something grand. </p><p>As Sturm says, this is a low-cost, worthwhile means for alleviating distress and filling people with gratitude and compassion. Given the state of the world, those qualities are in high demand. </p><p style="margin-left: 20px;">"I find it remarkable that the simplest intervention in the world – just a three-minute conversation at the beginning of the study suggesting that participants practice feeling awe on their weekly walks – was able to drive significant shifts in their daily emotional experience. This suggests promoting the experience of awe could be an extremely low-cost tool for improving the emotional health of older adults through a simple shift in mindset." </p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank" rel="noopener noreferrer">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank" rel="noopener noreferrer">Substack</a>.

In fact, the maximum human lifespan has barely changed since we arrived.
You might have seen the cartoon: two cavemen sitting outside their cave knapping stone tools. One says to the other: 'Something's just not right – our air is clean, our water is pure, we all get plenty of exercise, everything we eat is organic and free-range, and yet nobody lives past 30.'
