getting older

Science

It feels like time accelerates as we get older. An easy 60-second fix can help slow it down.

Some fascinating research shows that our perception of time may be linked to the length of our heartbeats.

Time accelerates as we get older, but there are some interesting ways we can slow it down.

Imagine this scenario, if you will: You're scrolling along, minding your own business on the internet, when this little nugget comes across your timeline: "1980 and 2023 are as far apart as 1937 and 1980. Sleep tight, old fogies!"


Wait, what? Your first reaction is, "That can't be right," so you pull out the calculator and do the math yourself—several times because you're sure you must've missed a number somewhere each time. You remember how long ago 1937 seemed in 1980, and there's absolutely no way that much time passed between 1980 and 2023. Buy you're wrong. As the warped reality of time washes over you, you sit in stunned silence, contemplating the existential crisis you've just been thrown into.

Why does time work this way? Why does it seem to get faster and faster and condense to make decades seem shorter and shorter as we age? And perhaps more importantly, how the heck do we stop time from feeling like a runaway freight train?

Here are a few theories about what creates the freight train phenomenon and what to do about it.

Time perception is relative—and kids perceive it differently

"Time flies when you're having fun" is a saying for a reason. Time also drags when you're doing drudgery work and feels like it stands still in moments of significance. And yet the ticking of seconds as they go by doesn't change tempo. We measure it with steady, unchanging beats, but how it feels changes constantly.

This relativity exists in every passing moment, but it also exists in the bigger picture as well. The years felt like they passed by much more slowly when we were children, and by middle age, they feel like they pass in the blink of an eye. The pandemic gave us an even greater sense of this relativity as disruptions to our normal routines and the stress associated with the COVID-19 years messed with our sense of time. (On an odd side note, surveys show that our time perception during the pandemic varied a lot from place to place—people in some parts of the world felt that time moved more slowly, while others felt time moved more quickly.)

According to a 2023 Hungarian study published in Nature Scientific Reports, very young children perceive time differently than older children and adults. Researchers split 138 people into three age groups—pre-kindergarten, school-age and adults 18 and over—and showed them two videos of the same duration, one that was "eventful" and one that was "uneventful." Interestingly, the pre-K group perceived the eventful video to be longer, while the older children and adults saw the uneventful video as longer.

The way the study participants described the length of the videos in gestures was also telling. Young children were much more likely to use vertical hand gestures, connoting volume or magnitude, to indicate a length of time than the other two age groups. School-aged kids and adults tended to use horizontal gestures, indicating time as linear, increasing with age.

Our neural processing slows down as we age

Professor Adrian Bejan has a theory based on how neurons process signals. As we age, our neural networks increase in size and complexity and, as a result, process visual information at a slower rate. That slower processing means we create fewer mental images each second than we did when we were younger, thereby making time seem to slow down.

“People are often amazed at how much they remember from days that seemed to last forever in their youth, Bejan shared with Harvard University. "It’s not that their experiences were much deeper or more meaningful; it’s just that they were being processed in rapid fire.”

In other words, processing the same number of mental images we did in our youth takes longer now, somewhat counterintuitively making time seem to pass more quickly. So goes the theory, anyway.

It might simply be about time-to-life ratios

Another popular theory about why time feels different as a child than it does as an adult is the ratio of any given day, week or year to the amount of time we've been alive. To a 5-year-old, a year is 20% of their entire life. For a 50-year-old, a year only is 0.2% of their life, so it feels like it went by much more quickly.

It's also a matter of how much change has happened in that year. A year in the life of a 5-year-old is full of rapid growth and change and learning and development. A year in the life of a 50-year-old probably isn't a whole lot different than when they were 48 or 49. Even if there are major life changes, the middle-aged brain isn't evolving at nearly the same rate as a child. A 50-year-old looking back at the past year will have a lot fewer changes to process than a 5-year-old, therefore the year will seems like it went by a lot faster.

“Our perception of days, weeks, years and that kind of time seems to be especially influenced by our perspective: Are we in the moment experiencing it, or are we looking backward on time?” psychology professor Cindy Lustig told the University of Michigan.

The key to slowing it all down? Be mindful of the present moment.

Lustig has a point. When we are in the moment, our perception of time is much different than when we look back. So, being fully conscious in the present moment can help us rein in the freight train effect.

One way to do that is to be mindful of your physical existence in this moment. Feel your heart beating. Feel your breath going in and out. Cornell University psychology professor Adam Anderson, Ph.D., conducted a study that found our perception of time may be linked with the length of our heartbeats. (Study participants were fitted with electrocardiograms and asked to listen to a brief audio tone. They perceived the tone as longer after a longer heartbeat and shorter after a shorter one.) He suggests starting a stopwatch, closing your eyes and focusing on your breathing for what you think feels like a minute. Then, check your time to see how accurate your estimation was.

“This can give you a sense of how much your experience of your body is related to your experience of time,” Anderson told WebMD. “It will help teach you to enjoy the pure experience of time.”

You can also use focused breathing to purposely slow down your heart rate, and thus slow down your time perception. “We show that slow heart rates—that is, a longer duration between heartbeats—dilates time, slowing it down," Anderson said.

We can also alter our perception of time by taking in novel experiences, such as traveling to new places. According to Steve Taylor, author of Making Time: Why Time Seems To Pass at Different Speeds and How to Control It, people who go on adventurous trips report that their vacations feel longer than those who choose a predictable destination. You can also make small changes to your daily routine, such as trying new foods or taking a new route home from work to take in some new stimuli and slow your perception of time.

A study in 2024 found that people who do intense exercise experience a time warp, feeling like they exercised longer than they really did, so if you want to temporarily slow down time, you can push your body hard during a workout.

Finally, try to take in the world the way you did as a small child. Take note of life's wonders. Engage fully in whatever you're doing. Notice details and take mental pictures as much as you can. Time goes by fast when we're distracted, so training our attention on the here and now can help. Ultimately, we can strive to perceive time more like we did when we were little, in its full depth and magnitude instead of a narrow, straight line.

Older people share surprising and simple ways they keep their brains healthy and sharp.

One of the biggest battles of healthy aging is staying mentally sharp. Having a healthy brain is important for mental and physical longevity.

Data from the Centers for Disease Control and Prevention (CDC) reports that 6.7 million older adults in the United States have Alzheimer’s disease, the most common type of dementia. The CDC notes that by 2060, that number will double.

However, being proactive about brain health can help keep aging brains thriving. In an online forum of Boomers and older Gen Xers, they opened up on how they keep their brains sharp and memory strong. These are 40 surprising (and simple) ways they've maintained healthy brains as they've aged.

"I take on-line college courses. Pick one out that piques my interest and sign up. The advantage at my age is I can study whatever I want, I'm not really concerned with advancing my career. Ancient Mediterranean History? Sure why not? History of Beer? Why not? Psychology of Evil? Sounds interesting. All on-line, all cheap. Keeps my brain active." - mike11172

"I'm way into fitness and still work out with weights. Also walk a lot and do fun things outdoors. I make sure that I get outside at least an hour every day. I'm careful to eat good foods that meet nutritional requirements, especially since I work out. I drink plenty of fresh filtered water. Taking care of your health in these three ways really makes a difference in one's mental sharpness and attitude. I belong to a religion that encourages me to treat others kindly and to be thankful for the life I have. Participate in activities that involve helping others. That really makes anybody feel good, have a purpose, and be glad they have the means to give of themselves. My husband and I make a point to always treat each other like we're newlyweds. Keeping the stress in your home to a minimum improves your mental state. In my down time, I've gotten into paper art. It's fun and an easy way for anyone to stay creative. I make cute things and greeting cards for others." - Bebe_Bleau

"Just use it. The brain works a lot like muscles in the sense that it will degrade quickly if you don't use it but can maintain its abilities for a long ass time if you do use it. I've met so many older people who basically just stop doing anything that requires a lot of thought when they get older because thinking is a lot of work. And you can definitely tell that kind of person when interacting with them. Conversations with them feel more like talking with a bunch of pre-recorded responses. Just do stuff that requires a lot of thought. Learn new skills. Read about complex, interesting ideas. Do puzzles. Play chess." - Yak-5000

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 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.

People in their 40s share life advice with people in their 30s.

Wisdom is accrued with years lived. Every generation has advice to pass down, and people in their 40s have a lot of life advice to share with those a decade behind them in age.

In an online forum, this question was posed to people in their 40s, asking, "For those in their 40s, what's something people in their 30s don’t realize will impact them as they get older?"

People in their 40s generously shared their best life advice and aging tips with those in their 30s. These are 16 of their most impactful pieces of wisdom on getting older.

But then you realize — one bad night’s sleep can ruin your whole day. Your back isn’t 'just sore,' it’s 'this is how it is now.' And everything that once felt automatic — stamina, resilience, even friendship — starts to require intention, care, and effort. The hardest part? You start to feel that 'everything’s ahead' doesn’t quite apply anymore. Some things are already behind you, and you have to learn to let go. Not cling to the past, not drag it with you. Because if you do, you’ll miss how strange and beautiful the now can actually be. And most importantly, she said — stop postponing things. Love, change, taking care of yourself.
