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.
