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

Here's a morbid question: 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 Cell found 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.

There is a three hour window of time when most dying people pass away.

Death is hard to think about and harder still to talk about. Some people get panic attacks just imagining the inevitable end of their life. It's an extremely uncomfortable and inescapable fact of living. For some people, learning as much as they can about what it's like and how it works is the one thing that brings them a little bit of comfort.

That's where Julie McFadden comes in. McFadden has been working as a hospice nurse for nine years. She has been educating people about the dying process on social media for almost as long, racking up millions of views with her gentle, reassuring, and highly informative FAQs.

In a recent video, Hospice Nurse Julie tackles a big, scary question: What time do people usually die? And can we actually predict someone's time of death?

"When is the most common time to die? I think you might be surprised what research says," she begins the video.

McFadden says even she was surprised when she started digging into the data and research. She noted that in her own work, she hasn't really seen a trend, but after poring through studies and speaking to colleagues throughout the hospice industry, she was taken aback to discover there was a clear answer to her question.

"Research and anecdotal evidence... it does show that most people die between 2 a.m. and 5 a.m.," she says. She explains that some professionals refer to this window as the "letting go hour."

Other studies and experts have a slightly different take, citing the most common time as 6 a.m.—8 a.m., or even peaking at 11 a.m. But the truth remains that there is a definitive pattern of a high percentage of people passing away in the wee hours of the morning or middle of the night.

"So, why does that happen? That's where my brain went. And to me, the reason why is the most fascinating part," she explains.

There are a few different factors, McFadden says, that explain such a narrow death window. The first relates to the normal cycle of our body's energy and alertness.

"Biologically, we have a circadian rhythm... And between the hours of two and five, that is when our body's energy level is the lowest. Our temperatures drop, our blood pressure drops, and our breathing slows."

She mentions that those late night/early morning hours are also typically very quiet, without a lot of interruption and stimulation that might unwittingly keep a patient engaged with the outside world. "There's less people kind of trying to hold you there."

The dying person's personality also plays a role. McFadden says she sees over and over that some patients will wait until the entire family arrives before they "let go," while others will wait until things are quiet and they're alone. More outgoing people may wait to be surrounded before they pass, while introverts may prefer to pass in solitude. For the folks who prefer peace and quiet, those nighttime hours make a lot of sense.

McFadden then shared a pretty wild story of a patient of hers who "chose" when to die. Viewers then chimed in with their own.

Most people who have lost a loved one absolutely insist that dying people are aware of, and have some level of control over, when they decide to let go. You should watch McFadden's video to hear her best story, but the comments were full of even more.

"My good friend Donna was dying in hospice from a brain tumor and a week before she passed things looked pretty grave so she wasn't expected to last another 2 days. Her sister was by her side and said it's okay you can go but she opened her eyes and said no I'm not going yet I'm waiting for my birthday, I'm dying on my birthday. Her birthday was a week away and no one thought she would make it but she did. Her sister whispered in her ear 'today is your Birthday Sis you made it' and then she passed within the hour," one user shared.

"My grandmother was actively dying for two weeks and held on until the wee hours of the first of the month. She was concerned about getting her social security check to help the family," said another.

"About a week before my 93 year old mom died, she adamently said a few times to me and others she was leaving the following Tuesday. At first I thought she meant she's going out... That Tuesday comes and it was clear she was probably not going to make it to end of the week. I was aware of her comments from the week before but didn't think it would happen that day. She died at 11:12 pm that night, on the day she said she was leaving. She knew."

"While not quite the same thing as 'predicted,' my mother said 'they' told her when she was going to pass away -- to the minute. 'They' being the people visiting her and promising to help her during her visioning experiences. She said they had shown her where she was going to go. She died at exactly the time her visioning-visitors had told her."

The stories shared by the hundreds in the comments to McFadden's video are heart-wrenching, but ultimately extremely hopeful.

McFadden doesn't want her viewers who may have a loved one who's dying to be more anxious and nervous during the night, worrying and potentially losing sleep.

"People are going to do it when they do it. Their body is going to let go when the body is ready to let go. All you can do is be there for your loved one the best you can."

She reiterates that, even for someone like her who has seen and helped many patients cross over from this world to the next, that death is a mystery. As much as we can continue to learn and understand new aspects of it, we'll never fully know what it's like until we experience it ourselves.

A man who hasn't dunked a basketball in several decades wants to see if he can still do it.

When you think of a person in their late 70s and the things they can do to stay active, you probably imagine things like walking, aqua fitness classes, or using light dumbbells or resistance bands. Easy stuff, right? The most important thing is to not push it too hard and end up getting injuries. At that age, many people are prone to falls and their bones are more brittle—which puts them at great risk of broken bones and other serious damage.

One of the highest impact and most intensive forms of exercise a person can do? Jumping. Even a lot of younger people don't like to do it too much because it's so hard on the knees and other joints. But the benefits for bone density, balance, coordination, and overall physical health are incredible, making it such a catch-22 activity for older seniors.

A 79-year-old recently decided he wanted to try to dunk a basketball. Even better, he's documenting the whole thing on YouTube.

Charlie Gross retired in 2013. He's a husband and grandfather who's always managed to stay fit. Back in his day, he was quite the athlete. "I would say for a 79-year-old I'm physically active and mentally in pretty good shape," he says.

Gross says the last time he was able to dunk a basketball on a regulation hoop, he was around 30. He remembers a volleyball game in the early '80s where he grabbed the volleyball and was able to dunk it. That was the last time he pulled it off successfully.

Gross works and volunteers as a gym teacher for homeschool students and was inspired by a vertical leap test he did with his class. He measured his vertical leap at 11 inches, which he calls "embarrassing"—the average vertical leap for most men is somewhere around 16-20 inches, but those numbers are typically for people much younger. An 11-inch vert at almost 80 years old is already impressive! Gross was teaching and training some of his students to increase their vertical leap, and he got the idea to see if any of the tips would work for him.

"Just seemed like kind of an interesting challenge to take on," he noted. And so be began his journey. He enlisted the help of his grandson, Zach, to create a mini "documentary" for YouTube.

For reference, Gross is 5' 10". He's in generally good physical health but, like anyone his age, he's been through some challenges including a partially torn rotator cuff and a bout with prostate cancer. Dunking a basketball is an enormous challenge, but Gross is up for it.

Toward the end of the first video, he runs a test to establish his baseline. With a light jogging start and after a couple of attempts, Gross can replicate his 11-inch vertical in real-world conditions.

In a follow-up video about two weeks later, the progress is remarkable.

Gross recounts his workout routine, which consisted of squats, standing jumps, weighted jumps with dumbbells, calf stretches, toe raises, farmers walks, and more. He's super cognizant of not pushing too hard and hurting himself. Gross is well aware that his age makes him an injury risk if he works out too strenuously or engages in too much high-impact training.

Another real-world test out in the driveway basketball court clocked Gross at about a 13-inch vertical. The update finishes up with Gross attempting to dunk on an eight-foot rim.

He's well on his way! Though the task remains daunting.

Gross posted his first video just two weeks ago as of this writing, and today he already has nearly 15,0000 subscribers and over 300,000 total views on his two updates. Commenters can't get enough and are so excited to root for him on his journey:

"What a LEGEND!!! So inspirational."

"The fact that you're 79 and you still have this lively and joyful mindset, and that your body is in remarkably good condition is just awesome. Kudos to you and good luck sir!"

"Yeah this man is who everyone should aspire to be like when they are older. Physically and mentally active at 79 is no easy feat. Kudos!"

"I DO NOT CARE WHETHER YOU SUCCEED OR FAIL...YOU ARE ALREADY A LEGEND FOR THIS!"

The physical benefits for people Gross' age when it comes to staying active are obvious. Regular movement and exercise can do wonders for your longevity, especially in your later years, and also improve your quality of life. He's 79 and so full of life he honestly seems decades younger. But the best thing we can take from Gross' example is his willingness to try something new and set a challenging goal for himself.

According to Pacific Angels Home Care, "In some regards, goal setting is especially important for seniors. It gives seniors control over their lives and allows them to reflect on what is important to them and what interests them. They can determine what will motivate them and give them purpose." The mental boost from working to achieve a goal helps fight off the depression that's so common in seniors. And besides, trying new things and challenging ourselves is a crucial part of being alive.

In one of his videos, Gross quotes Spock from Star Trek: "Live long and prosper," he says. I'd say, whether he ends up dunking or not, he's definitely prospering already!

A composer died in 2021, but a lab-grown version of his brain is still making new 'music'

Are the haunting tones proof of consciousness after death, or just a beautiful sentiment?

Guy Ben-Ary/YouTube & By Non Event - Alvin Lucier, CC BY-SA 2.0

Alvin Lucier''s "brain" is still composing music 3 years after his death.

I love the gag from Futurama where, when people die, their heads and brains are kept alive in a jar, allowed to carry on forever. Their body may have failed, but in a sense they can live on and on and on (as long as someone's there to lug them around). It's a fascinating idea, and one that's definitely being explored in various ways here in the real world.

For example, did you know that you can upload photos, videos, and audio clips of a deceased loved one and create an incredibly lifelike AI version of them? This may or may not be considered a good thing depending on how you view it, and though it's not true consciousness per se, it can be a frighteningly accurate blurring of the lines. Furthermore, some scientists insist that consciousness does not exist solely in the brain, and that one day we may be able to harness it when the living organs of the body have died. Heavy stuff!

A composer who passed away several years ago was also fascinated by the idea of his consciousness and art living on without him. So he devised a bizarre experiment.

The musician, composer Alvin Lucier, was not content to only make music for the duration of his natural lifetime. So he recruited a team from Harvard Medical School to harvest his stem cells after he passed away

From there, the stem cells were used to grow something resembling a clump of human brain matter. It's not a fully functioning brain, not even close, but it is living tissue derived from the DNA of the late musician. The experiment, then, was to determine just how much of Lucier really existed in this sample.

"The central question we want people to ask is: could there be a filament of memory that persists through this biological transformation? Can Lucier's creative essence persist beyond his death?" the team said, per the Art Newspaper.

Neuroscientists and artists teamed up to create an installation — part art, part science — called "Revivification." They connected the "in-vitro brain" to electrodes that would then transmit the electrical impulses generation by the brain matter to twenty humongous brass plates hung around, thus creating music. Or, at least, tones.

You can see the art installation and the behind the scenes in this video. If you want to hear the haunting tones that seem to originate from beyond the grave, you can get a listen at about 3:53.

- YouTubewww.youtube.com

Not only does the "organoid" generate signals that become sound through the brass panels, it also responds to the environment around it. Sound from the art gallery is captured by a microphone and fed back to the little mini-brain, which affects its electrode activity.

That makes the sounds generated inside the experiment totally unique and dynamic. If Lucier really "composing" this music, in a sense? Not really, but the bizarre sounds are being generated, in part, by his genetic material. That makes Revivification an absolutely fascinating blend of art, science, and maybe even a little spiritualism.

Revivification is probably not proof of consciousness after death, and it doesn't claim to be. But it asks interesting questions about the nature of memory, and where our creativity or spirit or soul or whatever you want to call it is really stored.

Perhaps the most touching aspect of the story is Lucier's unwillingness to ever stop creating new art, even after his death at the age of 90. You'd think that would be enough years to fully satisfy his need for self-expression! But not so.

When Lucien's daughter was told about the project, she laughed and said, "This is so my dad. Just before he died he arranged for himself to play for ever. He just can't go. He needs to keep playing."
