How long can you hang out? The answer may say a lot about your potential lifespan.

Would you really want to know how long you have to live? On one hand, it’d probably inspire you to go out and complete your bucket list. On the other, it may be depressing to know just how many days you have left. Well, science has yet to discover a way to determine the average person's life expectancy, but some indicators can show whether someone is in danger of having their life cut short by deteriorating health.

You could, if you were so inspired, shell out a bunch of money for fancy genetic and biological testing. Chasing immortality is all the rage with billionaires, so if you've got the money, you can find out an awful lot about how long you're likely to live.

Or you could just hit the gym or local playground and find out for free.

A study published by Clinical Interventions in Aging in 2019 determined that handgrip strength can be a reliable proxy for how long one has to live, or longevity.

One of the best ways to judge handgrip strength is to time how long you can hang from a bar. To test your grip strength, find yourself a pull-up bar, whether at a gym or local park, take a deep breath, and start hanging. Don't worry, you don't need to be able to do a pull up!

Ironically, the move is called a "dead hang." So-called, because you literally just hang there for as long as possible.

The literature revealed that 30 seconds is a good target for women and 60 is an excellent goal for men.

Therefore, if you go longer than the goal, you’re looking at a long life. But if you can’t quite get there, your life may be shorter than you’d like.

Dr. Peter Attia, founder of Early Medical and author of Outlive: The Science and Art of Longevity (2023), believes that grip strength is a great way to determine one’s overall health.

“It's just a great proxy for overall body strength and muscle mass, but I think it's also a very functional form of strength,” he said on The Drive podcast. “Basically, everything in your upper body is mediated through your hands. And if your grip is weak, everything downstream of that is weak. When you watch someone who's got a weak grip deadlifting it's very difficult for them to deadlift correctly because they don't create a proper wedge."

There are may ways to measure grip strength, but the dead hang is likely the simplest. When you think about it, it requires an incredible combination of shoulder mobility, spinal stability, core strength, and overall fitness. Not only are these all positive biological health markers, they're also all key to preventing falls as we get older.

Regularly practicing the dead hang, on the other hand, has incredible benefits including stretching your muscles and deloading your joints and spine, giving them a much needed rest.

Doctors Eve M. Glazier and Elizabeth Ko at UCLA Health say poor grip strength is connected to numerous diseases. “Research continues to link a decline in grip strength to a range of adverse health issues, including heart disease, arthritis, osteoporosis, Type 2 diabetes and certain cancers. It has also been found to be a predictor of the likelihood of post-surgical complications, post-surgical recovery time and mortality,” they wrote on the UCLA Health blog.

Weight can also significantly affect how long a person can hang from a bar. So, do lighter people have an unfair advantage over those on the heavier side? Well, weight is also an important indicator of longevity. A study published in Aging Cellfound a direct correlation between increased body mass and decreased longevity.

Other studies have elaborated on the findings: More important than your absolute grip strength and dead hang ability may be how it changes over time. Losing grip strength is a negative sign for your overall health, but maintaining or even building it is associated with better outcomes.

Another good reason to hit the gym regularly, at any age. No matter where you're starting, you want to do everything you can to maintain that level of strength as long as possible.

The good news for people who didn’t quite make their hang time goal is that you can improve it by practicing dead hangs.

How to perform a dead hang (according to Healthline):

  • Use a secure overhead bar. Use a step or bench to reach the bar with your arms easily. You don’t want to jump straight into a dead hang.
  • Grip the bar with an overhand grip (palms facing away from you). Aim to keep your arms shoulder-width apart.
  • Move your feet off the step or bench so you’re hanging on to the bar.
  • Keep your arms straight and stay relaxed.
  • If you’re new to the exercise, hang for 10 seconds. Then, work your way up to 45 seconds to 1 minute at a time.
  • Slowly step back onto the step or bench before releasing your arms. Repeat up to 3 times if you wish.
Grip strength is so strongly correlated with longevity that many medical professionals advocate for it being considered a true biomarker. A biomarkers is a regularly measured state of the body that's used as a key health indicator, like blood pressure or cholesterol. Grip strength, some say, should be regularly evaluated at medical check ups as an indicator of healthy aging.

A simple balance test can show your real biological age

Is your body older or younger than your chronological age?

A couple doing balance practice.

Your chronological age is the number of years you’ve lived, but that isn’t the greatest predictor of your health. Doctors often consider your biological age to determine your overall health or longevity.

There is no universal formula for determining someone’s biological age. Doctors usually consider one’s family health history, diseases, conditions, sleep, diet, and exercise habits. They can also determine someone’s biological age by checking their balance, grip strength and endurance.

A new study by the Mayo Clinic found that your ability to balance on one foot is an indicator of bone, nerve, and muscle strength and can help determine your biological age.

"Balancing on one leg requires multiple components of physiological function that each typically declines with age, including strength in the leg and postural stabilizing muscles, neuromuscular coordination, and intact sensory information and reflexes," Prof David Proctor, aging and exercise expert at Pennsylvania State University, told BBC Science Focus.


"Attempts to prevent or slow the loss of muscle strength and balance in older age could mean the difference between remaining functionally independent and early admission to a nursing home!" he continued.

The researchers asked people between the ages of 50 and 80 to balance for 30 seconds on each leg with their eyes open and closed. The team found that for every additional 10 years of age, swaying increased by 6.3% if their eyes were open and 10.5% if their eyes were closed.

So, if you are over 50 and can stand on one leg for 30 seconds without significant wavering, you’re probably doing well for your age. But if you experience considerable wavering, then you should work on training your neuromuscular system.

The study comes two years after researchers in Brazil found that older adults who cannot stand on one foot for 10 seconds or more are nearly twice as likely to die in the next 10 years. The inability to stand on one foot shows that the body has lost neuromuscular strength, but it also makes one vulnerable to falling.

“Remember that we regularly need to stay in a one-legged posture, to move out of a car, to climb or descend a step or stair and so on," the study’s author, Dr. Claudio Gil Soares de Araújo, a sports and exercise physician and director of research and education at the Exercise Medicine Clinic-CLINIMEX in Rio de Janeiro, said according to NBC News. “Aged people falling are at very high risk of major fractures and other related complications," Araújo wrote. "This may play a role in the higher risk of mortality.”

The same researchers found a similar test that predicted one’s risk of death. Araújo and his colleagues released a study in 2016 that found that one’ ability to sit on the floor and then stand up without using their knees or handles for support was a good indicator of longevity.

You begin the test with a score of 10 and subtract points on your way up and down for doing the following:

Hand used for support: -1 point

Knee used for support: -1 point

Forearm used for support: -1 point

One hand on knee or thigh: -1 point

Side of leg used for support: -1 point

Those who score in the lowest range, 0 to 3, had up to a 6 times greater chance of dying than those in the highest scores (8 to 10). About 40% of those in the 0 to 3 range died within 11 years of the study.

If you are having trouble with any of these exercises, you can improve by training your neuromuscular system through swimming, running, or cycling. Training programs are also available to help increase neuromuscular fitness. As with any exercise program, please consult a physician before attempting rigorous exercise.

It all can happen at just the right time.

Media outlets love to compile lists of impressive people under a certain age. They laud the accomplishments of fresh-faced entrepreneurs, innovators, influencers, etc., making the rest of us ooh and ahh wonder how they got so far so young.

While it's great to give credit where it's due, such early-life success lists can make folks over a certain age unnecessarily question where we went wrong in our youth—as if dreams can't come true and successes can't be had past age 30.


Weary of lists celebrating youngsters, television writer and producer Melissa Hunter sent out a tweet requesting a new kind of list for 2020. "Instead of 30 Under 3 or NextGen lists," she wrote, "please profile middle-aged people who just got their big breaks. I want to read about a mother of 2 who published her first novel, a director who released their first studio feature at 47, THAT'S THE LIST WE WANT."

The Twitterverse responded with a resounding "YAAASSS." Story after story of folks finding success in their 40s, 50s, and beyond began pouring in. If you worry that you're not far enough along in your 20s or 30s, or think it's too late for you to follow your passion in the autumn of your life, take a look at these examples of people crushing it in their mid-to-late adulthood.

Take this mother of four teens who released her first full-length book at 45 and started law school this year at age 47.

Or the woman who published two books in her late 50s and is revising book #3 at age 60. Oh, she also started running at age 45.

Another person shared how they got out of prison for drugs at age 49, stayed clean and started their own business, and broke the $1 million sales mark last year at 56.

"Lauching my clothing line now—at 48," wrote a mom of two. "Next venture feels amazing."

Another user chimed in with "Yes! Plus the 40 under 40, 30 under 30 can be quite contrived (sometimes). I want to see people juggling school, career, and family.”

Yet another mother of two teens finished her PhD at 41 and got a tenure-track position at age 47. She's also working on a book on Indigenous Early Childhood.

How about this woman who hadn't taken a math class for 40 years? She aced her statistics classes and will graduate with a perfect GPA after she turns 60. "Lots of life to live!" she says.

Another mom (are we seeing a theme here?) discovered a passion for interior design and won a national TV design challenge in her late 40s. Now, at 60, she has a successful design career and contributes to radio and magazines.

Of course, we also know there are fabulously successful folks who got a "late" start in Hollywood, including the incomparable Ava DuVernay, "who left her job at age 40 to focus on filmmaking and then became the first black woman to make over $100 million at the box office.”

As one man pointed out, "The idea that you've got five years between 20 and 30 to do everything you're ever going to do is ridiculous." Hunter agreed, writing, "The advice is always that it's a marathon, not a race, and I wanna read about the people who finished that marathon!!"

So many stories of people publishing their first books, landing their ideal jobs, or discovering a passion later in life just kept coming, and person after person shared how inspiring and motivating they were.

Of course, not everyone has lofty career goals. If these stories aren't quite hitting the mark for you, check out this woman's contribution to the conversation. She's "just a regular human," she says, but she went to Zimbabwe and volunteered at a wildlife refuge at age 47. "Life doesn't just peter out after 30," she wrote. "My friend Elsa is 96 and went on an archaeological dig at 75. I want to be like her."

Don't we all.

Age really is just a number, and there's nothing magical about "making it" in your younger years. Let's be sure to celebrate people living their best lives and making dreams come true at any and every age.

Boost your Brain: Lifestyle changes that enhance cognitive function in adults

Unlock the secrets to sharper thinking with simple lifestyle tweaks.

men's white crew-neck T-shirt

Do you often walk into a room and forget why you are there? Or when you sit down to read a book, do you end up reading the same paragraph over and over? If you experience these things frequently, you may be worried that your cognitive function is declining.

The brain structure changes and shrinks as we get older, which can result in minor cognitive decline. However, frequent disorientation, forgetfulness, and difficulty making decisions can be signs of serious cognitive impairment—such as dementia or Alzheimer’s disease—that significantly interferes with daily activities and reduces quality of life.

Fortunately, there are some measures you can take and lifestyle changes you can make to potentially improve cognitive function. Many factors contribute to Alzheimer’s disease and dementia risk, and these measures are by no means a guarantee that you won’t develop these conditions. However, they may help protect the brain from age-related cognitive decline by boosting brain connectivity and enhancing cognitive processes.

What are cognitive functions?

Cognitive function is an umbrella term that encompasses various brain activities, ranging from simple to complex. In other words, cognitive functions are the mental processes through which your brain communicates with your body to perform tasks. Some examples of cognitive functions include language abilities, reasoning, problem-solving, planning, decision-making, learning, attention, verbal fluency, knowledge acquisition, and information manipulation.

Types of cognitive impairment

Cognitive functions tend to naturally decline with age, making it difficult to distinguish normal, age-related changes in cognitive functioning from the early stages of disease-associated cognitive decline. For instance, memory difficulty, which is common in older individuals, is also a common symptom of dementia and Alzheimer's Disease.

Contrary to common misconceptions, not all forms of cognitive decline involve memory problems or difficulty thinking clearly. Some cognitive disorders initially present with sleep problems, behavioral or personality changes, such as poor judgment and impulsivity, or difficulty with environmental interactions.

Furthermore, depending on the cause, cognitive impairment may be temporary or progressive. For example, delirium, a mental state characterized by confusion and disorientation, is temporary, whereas all forms of dementia (including Alzheimer’s Disease) are progressive.

Age-related cognitive decline

Slight cognitive decline and some changes in cognitive performance are normal parts of aging. Most cognitive functions peak around age 30 and subtly decline with advancing age. Age-related cognitive impairments include difficulties with multitasking, retaining information, word-finding, and maintaining attention, as well as an overall decline in thinking and perceptual speed.

It is worth mentioning that not all cognitive abilities decline with age. For many, verbal reasoning, vocabulary, and other aspects of crystallized intelligence remain unchanged or improve with age.

Mild cognitive impairment

Mild cognitive impairment (MCI) refers to impairments in cognitive functioning, such as memory loss, that are more severe than in other people of the same age. While these changes in cognitive function are noticeable, they are not severe enough to qualify for a dementia or Alzheimer’s disease diagnosis, and they do not interfere with daily cognitive functioning.

Mild cognitive impairment can have various causes, including:

  • Nutritional deficiencies
  • Depression, anxiety, or other mental health conditions
  • Thyroid conditions
  • Autoimmune disorders
  • Not getting enough sleep
  • Infections
  • Medication side effects
  • Early stages of dementia

The cause of cognitive decline often determines the extent of compromised cognitive function in the individual and whether they can expect to suffer progressive cognitive decline. For those whose condition is not progressive, the symptoms of cognitive decline may slow or reverse, and many may return to their previous cognitive abilities.

However, for other individuals, cognitive decline may worsen over time and possibly progress to dementia or Alzheimer’s disease, diseases that significantly impair cognitive functioning.

Generally, individuals with mild cognitive impairment have an increased dementia risk, but mild cognitive impairment is not a guarantee of a future dementia diagnosis. Studies examining the risk factors for the progression of MCI to dementia indicate the risk of developing Alzheimer’s disease or dementia is three to five times higher for individuals diagnosed with MCI than for those with normal cognitive function.

Dementia

Dementia is characterized by a loss of behavioral and cognitive abilities that significantly interferes with a person's ability to perform daily tasks, resulting in a reduction in quality of life. The signs and symptoms of dementia typically present when healthy neurons stop working, lose connections, and die. Some neuron loss with age is normal; however, those with dementia experience a much greater loss of cognitive functions.

The signs and symptoms of dementia vary by individual, but typically include:

  • Memory loss and confusion
  • Sleep problems
  • Difficulty with fine and gross motor skills
  • Decline in executive functions (e.g., working memory, planning, emotional control, etc.)
  • Difficulty understanding and expressing thoughts
  • Problems reading and writing
  • Reduction in psychomotor speed
  • Repetitive questioning
  • Changes in diet and eating habits
  • Poor judgment and acting impulsively
  • Disorientation in familiar places
  • Taking longer to complete everyday tasks
  • Losing interest in daily activities
  • Hallucinating, delusions, and paranoia
  • Balance and mobility problems

There are several types of dementia, and all are progressive. The most common forms are Alzheimer's disease, in which abnormal protein plaques accumulate in the brain, Lewy-Body dementia, and vascular dementia, which results from blocked or leaky arteries in the brain. Although the underlying cause of dementia disease varies, the effect is the same—reduced cognitive abilities and cognitive impairment.

How to improve cognitive function

The brain shrinks as we age, and the number of synapses and neurotransmitter receptors—both allowing neurons to communicate with each other—decreases. These brain changes can cause minor cognitive impairment, particularly in memory, attention, processing speed, and planning. However, many lifestyle factors affect cognitive function, and changing your routine can help slow age-related cognitive decline.

Regular physical activity

Research shows that physical activity can have a beneficial effect on cognitive function in all age groups. Exercise increases blood flow to the brain and neurotrophins, including brain-derived neurotrophic factor (BDNF), which promotes neuron growth, repairs brain cells, and helps the brain develop new connections.

Exercise can also increase the volume of the hippocampus, a part of the brain responsible for forming new memories. Additionally, aerobic exercise is thought to be a factor in minimizing the risk of dementia and other neurological disorders, including Alzheimer’s disease.

Brain training

Brain training involves regularly engaging in cognitively stimulating activities and exercises challenging information processing and cognitive abilities. Examples include crossword and sudoku puzzles, jigsaws, problem-solving activities, reading and writing, and learning new skills and hobbies.

Memory training is a type of brain training designed to improve episodic memory—remembering events that occur in daily life—and working memory, a type of short-term memory essential to information manipulation. Memory training activities include puzzles, matching games, and word games that involve trying to remember as many words as possible in a given time.

Challenging the brain is known to build up cognitive reserves, aka the brain’s flexibility and agility. This can potentially reduce susceptibility to age-related changes in the brain and decline in cognitive functioning. As such, brain training can also lower the risk of developing Alzheimer's disease, dementia, and cognitive dysfunction. There’s a plus – regular brain training activities in one sphere can help improve your cognitive abilities in other areas, which, in turn, can preserve your overall cognitive ability.

Stay social

Humans are social animals. Positive social interactions can improve one’s quality of life and the ability to relate to others. People who are isolated may see a degradation of their cognitive ability sooner than those who stay engaged with others.

While research into social interactions and cognitive function is limited, a few trials have yielded positive results, indicating that positive social engagement can increase hippocampal volume and improve memory and overall brain health.

Sufficient rest

Sleep patterns change as we age, with sleep interruptions and early waking becoming increasingly common. Not getting enough sleep can negatively affect attention, memory, and executive functions (higher-level cognitive skills like flexible thinking and self-control).

Lifestyle changes can improve sleep patterns, which can support cognitive function. These include spending more time in the sunlight, maintaining a consistent sleep routine, taking short afternoon naps to counteract nighttime sleep loss, and seeking treatment for sleep problems and disorders like sleep apnea and insomnia.

Foods that can boost cognitive function

Research indicates certain foods can enhance cognitive abilities, protect the brain from damage, and slow cognitive decline. However, the mechanisms by which these foods impact cognitive functioning are unclear.

However, existing research indicates that certain nutrient components can reduce inflammation, oxidative damage, and the buildup of toxic proteins in the brain. These nutrient components may also promote the formation of new synapses and brain cells, prolong the life of existing brain cells, and support the lining of blood vessels, increasing the blood supply and oxygen to the brain.

Some of the best “brain foods” include:

Berries

Berries are rich in flavonoids and pelargonidin—natural plant pigments associated with enhanced memory, improved cognitive function, and a reduced risk of dementia and Alzheimer’s disease.

Green leafy vegetables

Green leafy vegetables are rich in brain-boosting nutrients like folate, beta carotene, vitamin K, and lutein. They can help slow cognitive decline and lower the risk of developing Alzheimer’s disease.

Oily fish

Fatty and oily fishes, like tuna and salmon, are rich in omega-4 fatty acids, which can lower levels of beta-amyloid—a protein that accumulates in the brains of patients with Alzheimer's disease—in the blood.

Legumes

Soybeans, black beans, kidney beans, and chickpeas have high concentrations of anti-inflammatory compounds that can support overall brain health and boost cognitive functioning.

Whole grains

Whole grains are an excellent source of phytonutrients, B vitamins, and antioxidants. They can significantly benefit brain function and lower the risk of dementia and Alzheimer’s disease.

Tumeric

This well-loved spice contains curcumin, a compound that may increase BDNF levels, lower the risk of dementia and Alzheimer’s disease, improve cognitive abilities, and support overall brain health.

Other brain-boosting Foods

Other foods that can improve cognitive function and mitigate cognitive decline include monounsaturated fatty acids, nuts, green tea, dark chocolate, and coffee. Some nutritional supplements, especially those containing vitamins D and B12, can also help support brain health and lower the risk of Alzheimer’s disease.

Conclusion

Cognitive abilities tend to decline as we get older, with many people experiencing subtle changes in cognitive function by or before middle age. However, if these age-related changes are more severe or frequently occurring than those of other individuals in the same age group, they may be signs of mild cognitive impairment.

While mild cognitive impairment does not always progress to dementia or Alzheimer’s disease, those with MCI are more likely to develop dementia and other conditions involving significant cognitive decline.

Some lifestyle factors can impact cognitive function and play a role in the likelihood of developing dementia, Alzheimer’s disease, and similar conditions. Positive lifestyle changes like brain and memory training, regularly exercising, sleeping well, engaging in social activities, and eating a healthy diet with plenty of “brain foods” can support overall brain health and improve cognitive function. As such, incorporating these lifestyle changes into daily life may help slow age-related cognitive decline, improve cognitive performance, and lower the risk of dementia and Alzheimer’s disease.
