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.

- YouTubewww.youtube.com

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!

Doctor says adults should score 8 points or higher on this simple longevity test

People who fail are more likely to die in six years.

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.

However, a doctor recently featured on the "Today" show says a straightforward test can reveal the likelihood that someone aged 51 to 80 will die in the near future. NBC News medical contributor Dr. Natalie Azar was on the "Today" show on March 8 and demonstrated how to perform the simple “sit to stand test” (aka sit-rising test or SRT) that can help determine the longevity of someone between 51 to 80.

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.


- YouTubewww.youtube.com

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


A 2012 study published by the European Society of Cardiology found a correlation between the SRT score and how long people live.

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.

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 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.


seniors, longevity, physical fitness, exercise, health, agingEven low-impact exercise like yoga can increase your mobility and flexibility and, thus, your SRT scoreCanva Photos

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 help (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 it's 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.

The Yanny vs. Laurel debate is back and what you hear could reveal the 'age' of your ears

What you hear might depend on your age.

What did you hear?

In 2015, many of us had our minds blown by the "Dress" debate. It started with a post and became an Internet sensation. Was the color of this random dress posted on social media black and blue, or white and gold? Arguments erupted. Scientists got involved. We looked at each other with suspicion. And for some, it was never truly resolved.

Fast forward three years, and the internet exploded again, this time with an auditory feud. A video started making the rounds with a simple recording of a word said over and over. Some heard "Laurel." Some heard "Yanny." None of it seemed to make sense. Two people could be sitting in the same room with the same speakers and hear two entirely different words.

- YouTubewww.youtube.com

Just as theorists came forward to explain the dress phenomenon, Reddit threads and YouTube channels exploded with explanations. Some thought it was the treble/bass settings that influenced what people heard in the recording. But that didn’t explain how people could listen from the same device and still hear different words.

Brad Story, a professor of Speech, Language, and Hearing at the University of Arizona, did a little digging. In the 2018 CNN article, "Yanny or Laurel: What Science Has to Say," writer Amanda Jackson notes that, "Story ran an acoustic analysis on the viral recording of the computerized voice. He also recorded himself saying 'Yanny' and 'Laurel' for comparison."

She shares that Story reported, "When I analyzed the recording of Laurel, that third resonance is very high for the L. It drops for the R and then rises again for the L. The interesting thing about the word 'Yanny' is that the second frequency that our vocal tract produces follows almost the same path, in terms of what it looks like spectrographically, as 'Laurel.'"

He also noted that if you alter the pitch of the recording, you might hear the other word. "Most likely, the original recording was ‘Laurel,’" Jackson adds. "If you heard 'Laurel,' you are the winner and have earned bragging rights for this round of the Internet debate."

But there's more to it. On the AsapSCIENCE YouTube channel, they reveal a few reasons for the divide. One is simply the power of suggestion. When the words are written on the screen, the mind might hear whichever word it sees first.

They also illustrate Professor Story's actual sound waves when saying the words "Laurel" and "Yanny," and explain that even though the waves are similar, what you hear might depend on your age. "The sounds of 'Yanny' play at a higher frequency than 'Laurel,' so if you're hearing 'Yanny,' you might have younger ears."

The video goes on to say that a Twitter (now X) user "posted audio of the pitch both brought down and up. When you listen to it brought down 30 percent, you will hear 'Yanny.' But when you listen to it brought up 30 percent, you'll likely hear 'Laurel.'"

- YouTubewww.youtube.com

On a blog post for the hearing aid company Miracle-Ear, they back up the theory. "The real mystery of Yanny vs. Laurel lies with sound frequency. The sound waves that allow us to hear 'Yanny' are at a higher frequency, whereas the sound waves that allow us to hear 'Laurel' are at a lower frequency. As we age, it’s common for us to start losing our ability to hear higher frequency sounds. It wouldn’t be surprising if someone younger hears 'Yanny' while someone older, listening through the same device, hears 'Laurel.'"

It’s all coming around again after the hosts from the Just The Nobodys Podcast revisited it on Instagram. One plays the sounds for the other, who hears "Yanny." He then exclaims, "Okay, since Yanny is a higher frequency, it requires younger and healthier ears to be able to hear it. But for older people, who don't have healthy ears, they're actually hearing Laurel."

The comment section was fired up as many of them argued with the premise.

"I'm 12, and I hear Laurel," said one.

Another claims they don't hear either: "I hear Yammy."

Amazingly, some hear both within two seconds:: "The first time I heard Laurel. The second, I heard Yanny."

And then, of course, there was this comment: "It's blue and black."

I guess we'll never truly know for sure.

Forget what you know about bed bugs. Avoiding and getting rid of them is pretty simple.

And thankfully, there are no toxic chemicals involved.

Mark Rober/YouTube

Mark Rober subjected himself to bed bug bites in the name of science.

"Good night! Sleep tight! Don't let the bed bugs bite!" This sing-songy rhyme that has been around for centuries alludes to the fact that bed bugs were prevalent in the past. After a significant decrease post-WWII, however, the sneaky pests have been making a comeback. Since the 1990s, bed bug infestations have risen dramatically, leading people to look for ways to avoid and get rid of the blood-sucking little buggers.

Unfortunately, a lot of the information about how to do that is flat-out wrong. Popular YouTube science communicator Mark Rober invites viewers to forget what we think we know and go on an educational journey with the leading bed bug researchers at Rutgers University's urban entomology lab. Not only did Rober subject himself to bed bug bites on purpose to see what happens when they feed, but he also conducted a series of experiments in the lab to find out what is actually effective at killing them and what is not.

Bed bugs have a reputation for being nearly impossible to get rid of, which isn't really the case, according to Rober. When you know what works, it's actually a fairly simple process to kill an infestation. And the good news is that it doesn't entail any toxic chemicals—in fact the pest control chemicals sold for bed bugs don't work at all, according to Rober's tests.

In the process of learning about bed bugs, Rober shared a few "super wild" facts about the infamous creatures.

Fact #1: Bed bugs can live 3 to 10 months without feeding.

Eek. No wonder it seems like it's impossible to get rid of them. Starving them doesn't work. They can live in the resting stage for 3 to 6 months, and if the environment is cold enough, they can survive around 300 days, or 10 months, without eating.

- YouTubewww.youtube.com

Fact #2: Bed bugs don't transmit disease

Some good news here: Unlike blood-sucking mosquitoes, bed bugs don't carry or transmit disease. The bad news on the front is that because they don't pose a disease threat, only an annoyance, there's not a big incentive to fund research to eradicate them.

Fact #3: Bed bugs are attracted to vertical objects

In one of Rober's experiments, he placed a dish with a cylindrical vertical post inside it an a dish without a column, and nearly all of the bed bugs in the enclosure ended up in the dish with the column. "If you think about it, humans sleep at the highest elevation any given room. So their logic is just crawl up any vertical surface you see until you eventually find a warm-blooded meal at the top."

Part of how they find humans is by smell, which is why certain strong-smelling items can act as a deterrent for bed bugs. In Rober's experiment, Bounce dryer sheets, moth balls, baking soda, and essential oils all seemed to repel bed bugs (as opposed to ultrasonic pest repellers, which appeared to have no effect). However, none of those things did anything to kill them.

Fact #4: Before 1950, one in three homes had bed bugs

Yikes. Even with the resurgence, we're still nowhere near those numbers, thank goodness.

Fact #5: The way bed bugs mate is weird

The term used to describe it is called "traumatic insemination," and really, you should just let Mark Rober explain it with his visual metaphor. Start at minute 11:30.

Two things work well to kill bed bugs—diatomaceous earth and heat

In testing chemical sprays, foggers, and other items marketed for killing bed bugs, Rober found a "superstar" in a natural, non-toxic substance. Diatomaceous earth—pulverized fossilized remains of tiny aquatic organisms called diatoms—was the most effective at killing the buggers with a 90% mortality rate after 10 days as opposed to 12% with the Hot Shot bed bug spray. Diatomaceous earth is mostly silica, which absorbs moisture, and when the silica dust sticks to the bed bugs as the walk through it, it dehydrates them. A light dusting of diatomaceous earth around all the cracks and crevices of a room is one way to kill off an infestation, though that process can take days.

The other way to kill bed bugs is heat. Steam kills bed bugs, as does heating up a room to over 122 degrees Fahrenheit does the trick. Temps over 122 degrees kills bed bugs instantly, and as Rober points out, there's no way for them to build immunity to this kind of treatment. So steamers and clothes dryers set to high are the average person's best bet for killing off bed bugs if they have them. The "nuclear option" is to have a pro come in with big heaters and cook your home for a day.

How do you avoid getting bed bugs in the first place?

An ounce of prevention is worth a pound of cure, and that's true for bed bugs especially. Avoiding an infestation if there's already one in your apartment building is trickier, but a lot of people inadvertently bring bed bugs home from hotel stays. Checking the underside of a hotel mattress as soon as you come in the room is a good habit to be in. Bed bugs poop a lot, and there will be spots along the edges of the mattress if bed bugs are present.

The other tip is to use the luggage rack to store your suitcase instead of leaving it on the floor or furniture and to hang clothes on the closet hangers instead of putting them into the hotel room's dresser drawers. Some people may even put their suitcase in the bathtub, at least until they've checked the bed for signs of poop.

Nobody wants to deal with bed bugs, but at least now we have clear evidence of what actually works to get rid of them and what doesn't. Cook them with heat/steam and dehydrate them with diatomaceous earth, and take some simple steps when traveling to lessen your chances of getting them in the first place.

Sleep tight, everyone!
