Visit these 'blue zones,' where people live the longest

Blue zones are regions with unusually high numbers of centenarians

Factors thought to contribute to longevity in these regions include diet and social connections, but their legitimacy is often questioned due to a lack of rigorous scientific methodology and potential record inaccuracies.

Why Hawaiians live longer

Hawaii has the longest life expectancy at birth out of all 50 states, according to the US Centers for Disease Control and Prevention. Key factors include strong healthcare, lots of sunlight, and active lifestyles.

Health span: The number of years one is active and disease-free

As scientific advances continue to extend the average human lifespan, many are now turning their attention toward extending "health span." The ultimate goal would be to extend one's health span to match one's lifespan, which would necessitate a shift in focus toward the pursuit of healthy aging. (Some users may experience a paywall.)

The formula behind super agers—those possessing health and cognitive skills of people decades younger

A study of about 1,400 super agers did not identify any underlying genetic mechanism for longevity. While researchers instead emphasized that sustainable habits involving positive social connections, sleep, mood, diet, exercise, and personal fulfillment help reduce long-term risks, there is no one-size-fits-all formula for everyone.

Moving your body every day is key to longevity

In an era of biohacking, where millionaires subject themselves to draconian routines and tests to de-age themselves, one study suggests a super simple key predictor of mortality: more than any other trait, how much subjects moved determined how long they'd live. Movement mattered even more than age in predicting overall life longevity. Researchers suggest this means we should all simply get outside a bit more. Read more about the study here.

Environment and genetics explain why animals have widely different lifespans

Both environmental conditions and genetic factors shape how long various animals live. For some creatures, colder conditions allow for less energy use and slower aging. Larger animals have fewer predators. While humans don't live the longest, we are a rare species that successfully lengthened its average lifespan over time.

Can fasting help you live longer?

Animal studies into the health benefits of calorie restrictions of 20%-40% suggest it extends life spans and reduces incidents of age-related diseases, including cancer. This article explores the research into fasting, calorie restriction, and longevity.

Helping support others in older age linked to longer life

Analysis of findings from a long-term study of older couples first interviewed in 1987 and then followed for the next five years found that individuals who lend support to friends, neighbors, and relatives live longer. Non-helpers were more than twice as likely to die as helpers during the five-year period. That's even after controlling for factors including age, gender, and physical and mental health.

The disparity in life expectancy between wealthy and impoverished nations has notably narrowed

In 1950, people in Norway lived to age 72, on average, while those in Mali lived to just 26. By 2015, the countries with the worst conditions had made such significant progress that the global average life expectancy had surpassed the rate of any nation in 1950.

The color blue is almost never mentioned in ancient Greek literature

Linguists have noted blue is regularly the last color to enter the language of most cultures. Researchers guess that the color's rarity in living organisms is partly the cause of its linguistic absence.

People who feel connected to nature also report a higher well-being

Based on data collected from over 38,000 participants across 75 countries, spending time appreciating Earth's beauty appears to increase one's satisfaction with life. Whether it's a hike in the woods, a dip in the ocean, or time spent watching the sunset, the findings held true across a wide range of economic, cultural, and environmental contexts. The findings also indicate that connection to nature fosters experiences of being present and attentive, which are strongly linked to mental health.

In 2026, Finland was named the world's happiest country for the ninth consecutive year based on its wealth, social safety network, and high life expectancy, among other factors.

How do 'dementia villages' work?

The goal of good dementia care is to preserve a patient's quality of life as the incurable disease progresses, maximizing their ability to lead normal lives and maintain their health and dignity. Dementia villages are small neighborhoods built for people with severe dementia, with typical neighborhood haunts like salons or grocery stores staffed by people trained in dementia care, helping residents maintain a sense of autonomy and connection.

Conservative estimates suggest that 21.1 billion tons of polymetallic nodules exist in this abyssal plain, but about 90% of the species in the area are unknown to scientists.
