Death: It’s hard to talk about, and sadly, even harder to avoid. That’s why everyone wants to know how long they will live and there are many indicators that can show whether someone is thriving or on the decline. But scientists have yet to develop a magic formula to determine exactly how long someone should expect to live. Which, let’s be real, is probably a good thing. Knowing exactly how much time you have left to enjoy your life could cause a lot of anxiety, to say the very least.

NBC News medical contributor Dr. Natalie Azar appeared on the TODAY show on March 8, 2023, to demonstrate a surprisingly simple test that may predict how long someone aged 51 to 80 has to live. The test is called the sit to stand test, also known as the sit-rising test or SRT, and it takes less than a minute to perform.

How to take the sit to stand test

The test is pretty simple. Go from standing to sitting cross-legged, and then go back to standing without using any parts of your body besides your legs and core to help you get up and down. The test measures multiple longevity factors, including heart health, balance, agility, core and leg strength and flexibility.

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

Two studies, 13 years apart, came to the same conclusion

A 2012 study published by the European Society of Cardiology found a correlation between the SRT score and how long people live. A follow-up study published in 2025 in the European Journal of Preventive Cardiology further confirmed the SRT as a strong predictor of both natural and cardiovascular causes of death, reinforcing the original findings.

The study was conducted on 2002 people, 68% of whom were men, who performed the SRT test and were followed by researchers in the coming years. The study found that “Musculoskeletal fitness, as assessed by SRT, was a significant predictor of mortality in 51–80-year-old subjects.”

Those who scored 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.

What does your score actually mean?

Azar distilled the study on TODAY saying: “The study found that the lower the score, you were seven times more likely to die in the next six years.”

“Eight points or higher is what you want,” Azar said. “As we get older, we spend time talking cardiovascular health and aerobic fitness, but balance, flexibility and agility are also really important,” she stressed. A score of eight or nine means you’re allowed to roll forward onto your knees and then rise, which a lot of people will find more comfortable. If you can rise that way, you’re still in a pretty good spot health wise.

One should note that the people who scored lowest on the test were the oldest, giving them a naturally elevated risk of death.

Dr. Greg Hartley, Board Certified Geriatric Clinical Specialist and associate professor at the University of Miami, told the Atlanta Journal-Constitution that we should take the study with a grain of salt. “Frailty, strength, muscle mass, physical performance: those things are all correlated to mortality, but I would caution everybody that correlation doesn’t mean causation,” he said.

And of course, the test doesn’t take into account injuries or disabilities that may make doing the test impossible. But one of the study’s authors says that the study is a call to take our mobility seriously.

“The more active we are the better we can accommodate stressors, the more likely we are to handle something bad that happens down the road,” Dr. Claudio Gil Araujo, told USA Today.

What to do if your score is low

What should you do if you can’t manage a good score on the SRT? First of all, don’t panic! It’s never too late to improve your overall health, fitness, and strength, so regular exercise is a great thing to incorporate if you’re not already doing it.

A couple of specific skills that will help are boosting your ankle flexibility, hip mobility, and core strength. Trainers recommend incorporating squats, lunges, and planks into your regular routine. Just using your own bodyweight is plenty to get started, though if you’re up for incorporating any added loads, the strength training will do wonders for your bone density, as well.

But remember that the SRT is just a measure of strength and mobility, which could correlate to an older person’s likelihood of suffering from a fatal fall. It doesn’t do anything to measure your cardiovascular health (vitally important especially in older people), for example. And it may not even be the most reliable longevity test out there. It has been criticized for its extremely unnatural range of motion. For starters, rising by pushing up on the sides of our ankles with our knees pointed outward is certainly not representative of a real-life situation. Some doctors insist that your comfortable walking speed is a better indicator of health and longevity, while others say grip strength is the key measurement.

Remember, it is never too late to start healthy routines for a better quality of life.

A single door can open up a world of endless possibilities. For homeowners, the front door of their house is a  gateway to financial stability, job security, and better health. Yet for many, that door remains closed. Due to the rising costs of housing, 1 in 3 people around the world wake up without the security of safe, affordable housing. 

Since 1976, Habitat for Humanity has made it their mission to unlock and open the door to opportunity for families everywhere, and their efforts have paid off in a big way. Through their work over the past 50 years, more than 65 million people have gained access to new or improved housing, and the movement continues to gain momentum. Since 2011 alone, Habitat for Humanity has expanded access to affordable housing by a hundredfold. 

A world where everyone has access to a decent home is becoming a reality, but there’s still much to do. As they celebrate 50 years of building, Habitat for Humanity is inviting people of all backgrounds and talents to be part of what comes next through Let’s Open the Door, a global campaign that builds on this momentum and encourages people everywhere to help expand access to safe, affordable housing for those who need it most. Here’s how the foundation to a better world starts with housing, and how everyone can pitch in to make it happen. 

Globally, almost 3 billion people, including 1 in 6 U.S. families, struggle with high costs and other challenges related to housing. A crisis in itself, this also creates larger problems that affect families and communities in unexpected ways. People who lack affordable, stable housing are also more likely to experience financial hardship in other areas of their lives, since a larger share of their income often goes toward rent, utilities, and frequent moves. They are also more likely to experience health problems due to chronic stress or environmental factors, such as mold. Housing insecurity also goes hand-in-hand with unstable employment, since people may need to move further from their jobs or switch jobs altogether to offset the cost of housing. 

Affordable homeownership creates a stable foundation for families to thrive, reducing stress and increasing the likelihood for good health and stable employment. Habitat for Humanity builds and repairs homes with individual families, but it also strengthens entire communities as well. The MicroBuild® Initiative, for example, strengthens communities by increasing access to  loans for low-income families seeking to build or repair their homes. Habitat ReStore locations provide affordable appliances and building materials to local communities, in addition to creating job and volunteer opportunities that support neighborhood growth. 

Everyone can play a part in the fight for housing equity and the pursuit of a better world. Over the past 50 years, Habitat for Humanity has become a leader in global housing thanks to an engaged network of volunteers—but you don’t need to be skilled with a hammer to make a meaningful impact. Building an equitable future means calling on a wide range of people and talents.Here’s how you can get involved in the global housing movement:

Speaking up on social media about the growing housing crisis 

Volunteering on a Habitat for Humanity build in your local community

Travel and build with Habitat in the U.S. or  in one of 60   countries where we work around the globe

Join the Let’s Open the Door movement and, when you donate, you can create your own personalized door 

Shop or donate at your local Habitat ReStore

Every action, big and small, drives a global movement toward a better future. A safe home unlocks opportunity for families and communities alike, but it’s volunteers and other supporters, working together with a shared vision, who can open the door for everyone.

Most of us have a desire to improve our health, sleep more soundly, have more energy and just generally feel better in our daily lives. And yet those things feel elusive to many of us, so we’re always on the hunt for hacks that can help us, and if those hacks don’t require a huge change in lifestyle or herculean feats of willpower, all the better.

Thankfully, there’s one small change you can make to your morning routine that can make a big difference in how you feel, think and sleep, and it’s refreshingly simple.

The simple morning habit that changes everything

In a nutshell: Go outside and face the sun. More specifically, go outside as soon as possible after waking, but definitely within the hour, and look toward the sun for 2 to 10 minutes if it’s a bright, sunny day and a little longer on a cloudy one.

Most of us know we get vitamin D from sun exposure on our skin, but that’s really not what getting morning sunlight is about. It’s about the sun’s light energy hitting our eyes.

As Dr. Andrew Huberman, associate professor of neurobiology and ophthalmology at Stanford University School of Medicine, explains, “This is not some ‘woo’ biological thing. This is grounded in the core of our physiology. There are literally hundreds if not thousands of quality peer-reviewed papers showing that light viewing early in the day is the most powerful stimulus for wakefulness throughout the day and it has a powerful positive impact on your ability to fall and stay asleep at night.”

Huberman calls it a “power tool” for getting a great night’s sleep and lists it as one of the six pillars people should invest in every day—morning sunlight, daily movement, quality nutrition, stress control, healthy relationships and deep sleep.

Take care of yourself and take care of others. Daily investment in the 6 pillars is the way: morning sunlight, daily movement, quality nutrition, stress control, healthy relationships, deep sleep. Re-up every 24hrs so you can contribute and support others consistently too.— Andrew D. Huberman, Ph.D. (@hubermanlab) October 23, 2023

While the advice to look toward the sun flies in the face of all the times we’ve been warned not to look at the sun, in the early morning, the sun is less intense and you........
