If you are in your 60s, 70s, or 80s, five everyday abilities may tell you more about how well you are aging than how young you look or what the scale says.
These are not gym tricks. They are simple physical abilities researchers have linked to living longer, staying mobile, and remaining independent. When they start to decline, everyday tasks like getting out of a chair, climbing stairs, or moving safely around your home can become much harder.
The good news is that these abilities can be tested at home, and in many cases, they can be improved. Here are the five to know, how to test each one safely, and what your results may mean.
Safety first: Try these checks with someone nearby, in a clear space with good lighting. Stop right away if you feel dizzy, short of breath, or have chest pain, and seek medical help if those symptoms occur.
1. Walking Speed
Of all the physical signs researchers have studied in older adults, walking speed is one of the most thoroughly studied.
A large analysis pooled data from thousands of older adults and found that walking speed alone predicted remaining years of life about as well as long lists of medical information. The reason is simple: walking at a normal pace requires your heart, lungs, muscles, nerves, joints, inner ear, and brain to work together at the same time. When walking speed drops, it is often the first visible sign that one of those systems has less reserve than it used to.
Reserve is what carries you through an illness, a fall, or a hospital stay.
How to test it: Measure 13 feet in a hallway and mark a start line and a finish line with tape. Stand with your toes at the start line. Walk at your normal, comfortable pace, not your fastest, while someone times you on a phone until your foot crosses the finish line. Do it twice and keep the faster time.
How to read it: Four seconds or less is in the healthy aging zone. In one large study, the risk of death, hospitalization, and serious disability stayed flat at that speed and above. About five seconds lines up with the average life expectancy for your age and sex. About six and a half seconds or longer puts you in the highest risk group, where doctors are encouraged to look for causes that can be fixed.
These patterns even held up in people over 90. In that age group, slower walkers had about a 74 percent higher risk of death than faster walkers.
The relationship is gradual, not all or nothing. Every small drop in speed carries a little more risk, which means every small gain counts too. Older adults who got faster over the course of a year tended to live longer than those who did not.
2. Grip Strength
It may seem odd that your hand could say anything about your lifespan, but grip strength reflects your total body muscle. Muscle is where your body stores protein it can draw on when you are sick, injured, or recovering from surgery.
Clinicians have seen this many times: two people the same age have the same operation, and the one with more muscle often recovers faster and gets home sooner.
In a large national study, people in the weakest quarter for their sex had more than twice the risk of death of everyone else. Among women, every 11 pounds of lost grip strength was linked to roughly a 45 to 49 percent higher risk. This pattern held up all the way into the 90s and beyond. In a 2016 review of people in their 90s and 100s, strong grip was one of only three abilities that independently predicted living longer.
As a rough guide, a grip below about 60 pounds for men or about 35 pounds for women is considered low. You would need a device called a dynamometer to measure it exactly. Many physical therapy offices and some doctors offices have one, and versions are also available to buy online.
Everyday clues matter too. Trouble opening jars, carrying a full grocery bag, or turning a stiff doorknob is worth mentioning at your next doctor visit if you are struggling with them.
A strong grip does not guarantee strong legs, so it is worth checking both. That leads to the next test.
3. Standing Up From a Chair Without Using Your Hands
This test has some of the most striking numbers in aging research.
In a study of very old adults in Denmark, men who could rise from a chair without their hands had an 11.2 percent chance of reaching 100 years old. Men who could not had a 1.5 percent chance. For women, the numbers were 22 percent versus 2.4 percent. In other words, people who could do it were about seven to nine times more likely to reach 100.
The reason is that standing up depends on the large muscles in your thighs and hips. Those are the same muscles you use to get off a toilet, out of a car, out of bed, and up the stairs. Leg muscles also tend to lose strength faster with age than arm muscles. When this ability goes, it is often what moves a person from living independently to needing help.
How to test it: Use a sturdy chair without wheels, pushed back against a wall. Sit with your feet flat and your arms crossed over your chest. Stand all the way up, then sit back down. If that goes well, try five times in a row as quickly as you safely can and have someone time you.
Around 12 seconds or less is in the top scoring range clinicians use. More than about 15 seconds is where clinicians often start looking more closely at strength and fall risk.
4. Overall Physical Performance, Including the 10-Second Turn Test
Researchers found that combining balance, walking, and leg strength into one score predicts survival better than looking at any one of them alone.
The most common combined test is called the short physical performance battery. It has three parts: you hold three balance positions for 10 seconds each, you do a short timed walk, and you do five timed chair stands. It is scored from zero to 12.
Compared with people who scored 10 to 12, the odds of death were about one and a half times higher for scores of seven to nine, about two and a half times higher for scores of four to six, and more than three times higher for scores of zero to three. A score of six or below is used by the American Heart Association to identify frailty. Even a single point on the scale is considered a meaningful change.
This brings us to a related test that takes only about 10 seconds to do, called the timed up and go. Start seated in a sturdy chair. When someone says go, stand up, walk at your normal pace to a line 10 feet away, turn around, walk back, and sit down.
Under 10 seconds is a good result. Over 15 seconds is linked to a clearly higher risk. In adults over 80, this one test predicted long-term survival better than the individual measures did on their own.
The reason is that it checks standing up, walking, turning, and sitting down in one smooth sequence. Turning and sitting are moments when many falls happen, and you cannot fake your way through this test.
5. Thinking and Memory
Thinking and memory are not physical in the usual sense, but they rank alongside the physical measures as one of the strongest predictors of reaching very old age.
In people in their 90s and 100s, normal cognition was linked to about a 45 percent lower risk of death. Scoring 24 or higher out of 30 on a standard memory and thinking screen roughly tripled to quadrupled the chance of reaching 100.
In studies of twins, the twin with better thinking tended to outlive the other, even though they shared the same genes and the same upbringing.
Part of the reason is practical. Sharp thinking helps you manage medications, notice when something is wrong, keep up with friends and activities, and keep cooking and eating well.
Hearing loss, vision problems, low mood, and certain medications can all drag down thinking scores, and each of those can be addressed individually. If you notice changes in memory or thinking, bring them up with your doctor rather than assuming they are just normal aging.
The Surprising Truth About People Who Live to 100
Most centenarians are not perfectly healthy. When researchers examined people who lived to 100, a large share had chronic illnesses, muscle loss, frailty, and hearing and vision problems. They did develop heart disease and diabetes, and often not much later than most people.
What set them apart was not the absence of disease. It was what they held on to: their ability to walk, stand up, grip, balance, and think, even while living with health problems.
That matters because many people over 60 assume a diagnosis means they have already lost the longevity game. The evidence points the other way. Your diagnoses are only one part of the picture, and your function is the part you have the most ability to influence.
What to Do If You Did Not Score as Well as You Hoped
First, remember that these cutoffs are guides, not verdicts. Every one of these measures works on a sliding scale. Moving from slow to a little less slow carries real benefits. You do not have to reach the top category to gain ground.
Second, a low score is a reason to look for causes, because many of them are fixable. These include medication side effects, foot or joint pain, low vitamin B12, an underactive thyroid, poor vision, and fear of falling, which can cause people to walk slower and move less.
The most useful step is to write down your times and bring them to your doctor. Ask whether physical therapy makes sense for you, since a therapist can measure these tests precisely and build a program around your results.
Across the research, strength training is the most consistently supported way to improve chair rises, walking speed, and balance, and it works even when people start in their 70s and 80s.
The Bottom Line
If you can still do these things between 60 and 80, you have something worth protecting. You can walk briskly, stand up without your hands, grip firmly, keep your balance through a turn, and think clearly.
If you cannot do all of them yet, your results today are a starting point, and every one of these numbers is something you can work on. Small, steady gains in walking, strength, balance, and thinking add up to something much bigger: the ability to keep doing the things you love, without having to rely on others for everyday tasks.
