What’s the difference? is a new editorial product that explains the similarities and differences between commonly confused health and medical terms, and why they matter.
It’s the time of the year for coughs, colds and sore throats. So you might have heard people talk about having a “strep throat”.
But what is that? Is it just a bad sore throat that goes away by itself in a day or two? Should you be worried?
Here’s what we know about the similarities and differences between strep throat and a sore throat, and why they matter.
How are they similar?
It’s difficult to tell the difference between a sore throat and strep throat as they look and feel similar.
People usually have a fever, a bright red throat and sometimes painful lumps in the neck (swollen lymph nodes). A throat swab can help diagnose strep throat, but the results can take a few days.
Thankfully, both types of sore throat usually get better by themselves.
How are they different?
Most sore throats are caused by viruses such as common cold viruses, the flu (influenza virus), or the virus that causes glandular fever (Epstein-Barr virus).
These viral sore throats can occur at any age. Antibiotics don’t work against viruses so if you have a viral sore throat, you won’t get better faster if you take antibiotics. You might even have some unwanted antibiotic side-effects.
But strep throat is caused by Streptococcus pyogenes bacteria, also known as strep A. Strep throat is most common in school-aged children, but can affect other age groups. In some cases, you may need antibiotics to avoid some rare but serious complications.
In fact, the potential for complications is one key difference between a viral sore throat and strep throat.
Generally, a viral sore throat is very unlikely to cause complications (one exception is those caused by Epstein-Barr virus which has been associated with illnesses such as chronic fatigue syndrome, multiple sclerosis and certain cancers).
But strep A can cause invasive disease, a rare but serious complication. This is when bacteria living somewhere on the body (usually the skin or throat) get into another part of the body where there shouldn’t be bacteria, such as the bloodstream. This can make people extremely sick.
Invasive strep A infections and deaths have been rising in recent years around the world, especially in young children and older adults. This may be due to a number of factors such as increased social mixing at this stage of the COVID pandemic and an increase in circulating common cold viruses. But overall the reasons behind the increase in invasive strep A infections are not clear.
Another rare but serious side effect of strep A is autoimmune disease. This is when the body’s immune system makes antibodies that react against its own cells.
The most common example is rheumatic heart disease. This is when the body’s immune system damages the heart valves a few weeks or months after a strep throat or skin infection.
Around the world more than 40 million people live with rheumatic heart disease and more than 300,000 die from its complications every year, mostly in developing countries.
However, parts of Australia have some of the highest rates of rheumatic heart disease in the world. More than 5,300 Indigenous Australians live with it.
Why do some people get sicker than others?
We know strep A infections and rheumatic heart disease are more common in low socioeconomic communities where poverty and overcrowding lead to increased strep A transmission and disease.
However, we don’t fully understand why some people only get a mild infection with strep throat while others get very sick with invasive disease.
We also don’t understand why some people get rheumatic heart disease after strep A infections when most others don’t. Our research team is trying to find out.
How about a vaccine for strep A?
There is no strep A vaccine but many groups in Australia, New Zealand and worldwide are working towards one.
For instance, Murdoch Children’s Research Institute and Telethon Kids Institute have formed the Australian Strep A Vaccine Initiative to develop strep A vaccines. There’s also a global consortium working towards the same goal.
Companies such as Vaxcyte and GlaxoSmithKline have also been developing strep A vaccines.
What if I have a sore throat?
Most sore throats will get better by themselves. But if yours doesn’t get better in a few days or you have ongoing fever, see your GP.
Your GP can examine you, consider running some tests and help you decide if you need antibiotics.

Fast-Pickled Cucumbers
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Pickled vegetables are great for the gut, and homemade is invariably better than store-bought. But if you don’t have pickling jars big enough for cucumbers, and don’t want to wait a couple of weeks for the results, here’s a great way to do it quickly and easily.
You will need
- 1 large cucumber, sliced
- 2 tbsp apple cider vinegar
- 1½ tbsp salt (do not omit or substitute)
- 3 cloves garlic, whole, peeled
- 3 large sprigs fresh dill
- 2 tsp whole black peppercorns
- ½ tsp crushed red pepper flakes
- 1 bay leaf
Method
(we suggest you read everything at least once before doing anything)
1) Mix the vinegar and salt with 1½ cups of water in a bowl.
2) Assemble the rest of the ingredients, except the cucumber, into a quart-size glass jar with an airtight lid.
3) Add the cucumber slices into the jar.
4) Add the pickling brine that you made, leaving ½” space at the top.
5) Close the lid, and shake well.
6) Refrigerate for 2 days, after which, serve at your leisure:
Enjoy!

Sometimes, less is more:
Slow and steady wins the race?
Here’s the rundown… Slowly:
- You burn more body fat: running at 50-60% of max heart rate primarily burns fat without having the usual compensatory metabolic slump afterwards, unless you go for a very long time.
- You can build more muscle: lower-intensity workouts improve muscle recovery, which is essential too.
- You can reduce muscle soreness: light jogging helps clear lactic acid faster (10almonds note: muscle soreness after exercise isn’t about lactic acid)
- You avoid injuries: less impact on joints reduces injury risk.
- You learn the proper form: running slowly allows better focus on technique.
- You can enjoy it more: slower pace lets you take in surroundings and boosts mood.
- You still improve your cardiorespiratory fitness: strengthens heart and lungs over time.
- You’ll burn more calories than you think: can burn 200–400 calories per 30 minutes.
- You’ll improve your mobility: gentle movement supports joint health and collagen production.
- You can improve your performance: builds endurance and strength for faster running

For Seniors With Hoarding Disorder, a Support Group Helps Confront Stigma and Isolation
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
A dozen people seated around folding tables clap heartily for a beaming woman: She’s donated two 13-gallon garbage bags full of clothes, including several Christmas sweaters and a couple of pantsuits, to a Presbyterian church.
A closet cleanout might not seem a significant accomplishment. But as the people in this Sunday-night class can attest, getting rid of stuff is agonizing for those with hoarding disorder.
People with the diagnosis accumulate an excessive volume of things such as household goods, craft supplies, even pets. In extreme cases, their homes become so crammed that moving between rooms is possible only via narrow pathways.
These unsafe conditions can also lead to strained relationships.
“I’ve had a few relatives and friends that have condemned me, and it doesn’t help,” said Bernadette, a Pennsylvania woman in her early 70s who has struggled with hoarding since retiring and no longer allows guests in her home.
People who hoard are often stigmatized as lazy or dirty. NPR, Spotlight PA, and KFF Health News agreed to use only the first names of people with hoarding disorder interviewed for this article because they fear personal and professional repercussions if their condition is made public.
As baby boomers age into the group most affected by hoarding disorder, the psychiatric condition is a growing public health concern. Effective treatments are scarce. And because hoarding can require expensive interventions that drain municipal resources, more funding and expertise is needed to support those with the diagnosis before the issue grows into a crisis.
For Bernadette, the 16-week course is helping her turn over a new leaf.
The program doubles as a support group and is provided through Fight the Blight. The Westmoreland County, Pennsylvania, organization started offering the course at a local Masonic temple after founder Matt Williams realized the area lacked hoarding-specific mental health services.
Fight the Blight uses a curriculum based on cognitive behavioral therapy to help participants build awareness of what fuels their hoarding. People learn to be more thoughtful about what they purchase and save, and they create strategies so that decluttering doesn’t become overwhelming.
Perhaps more importantly, attendees say they’ve formed a community knitted together through the shared experience of a psychiatric illness that comes with high rates of social isolation and depression.
“You get friendship,” said Sanford, a classmate of Bernadette’s.
After a lifetime of judgment, these friendships have become an integral part of the changes that might help participants eventually clear out the clutter.
Clutter Catches Up to Baby Boomers
Studies have estimated that hoarding disorder affects around 2.5% of the general population — a higher rate than schizophrenia.
The mental illness was previously considered a subtype of obsessive-compulsive disorder, but in 2013 it was given its own diagnostic criteria in the Diagnostic and Statistical Manual of Mental Disorders, the DSM-5.
The biological and environmental factors that may drive hoarding are not well understood. Symptoms usually appear during the teenage years and tend to be more severe among older adults with the disorder. That’s partly because they have had more time to acquire things, said Kiara Timpano, a University of Miami psychology professor.
“All of a sudden you have to downsize this huge home with all the stuff and so it puts pressures on individuals,” she said. In Bernadette’s case, her clutter includes a collection of VHS tapes, and spices in her kitchen that she said date back to the Clinton administration.
But it’s more than just having decades to stockpile possessions; the urge to accumulate strengthens with age, according to Catherine Ayers, a psychiatry professor at the University of California-San Diego.
Researchers are working to discern why. Ayers and Timpano theorize that age-related cognitive changes — particularly in the frontal lobe, which regulates impulsivity and problem-solving — might exacerbate the disorder.
“It is the only mental health disorder, besides dementia, that increases in prevalence and severity with age,” Ayers said.
As the U.S. population ages, hoarding presents a growing public health concern: Some 1 in 5 U.S. residents are baby boomers, all of whom will be 65 or older by 2030.
This population shift will require the federal government to address hoarding disorder, among other age-related issues that it has not previously prioritized, according to a July report by the Democratic staff of the U.S. Senate Special Committee on Aging, chaired then by former Sen. Bob Casey (D-Pa.).
Health Hazards of Hoarding
Clutter creates physical risks. A cramped and disorderly home is especially dangerous for older adults because the risk of falling and breaking a bone increases with age. And having too many things in one space can be a fire hazard.
Last year, the National Fallen Firefighters Foundation wrote to the Senate committee’s leadership that “hoarding conditions are among the most dangerous conditions the fire service can encounter.” The group also said that cluttered homes delay emergency care and increase the likelihood of a first responder being injured on a call.
The Bucks County Board of Commissioners in Pennsylvania told Casey that hoarding-related mold and insects can spread to adjacent households, endangering the health of neighbors.
Due to these safety concerns, it might be tempting for a family member or public health agency to quickly empty someone’s home in one fell swoop.
That can backfire, Timpano said, as it fails to address people’s underlying issues and can be traumatic.
“It can really disrupt the trust and make it even less likely that the individual is willing to seek help in the future,” she said.
It’s more effective, Timpano said, to help people build internal motivation to change and help them identify goals to manage their hoarding.
For example, at the Fight the Blight class, a woman named Diane told the group she wanted a cleaner home so she could invite people over and not feel embarrassed.
Sanford said he is learning to keep his documents and record collection more organized.
Bernadette wants to declutter her bedroom so she can start sleeping in it again. Also, she’s glad she cleared enough space on the first floor for her cat to play.
“Because now he’s got all this room,” she said, “he goes after his tail like a crazy person.”
Ultimately, the home of someone with hoarding disorder might always be a bit cluttered, and that’s OK. The goal of treatment is to make the space healthy and safe, Timpano said, not to earn Marie Kondo’s approval.
Lack of Treatment Leaves Few Options
A 2020 study found that hoarding correlates with homelessness, and those with the disorder are more likely to be evicted.
Housing advocates argue that under the Fair Housing Act, tenants with the diagnosis are entitled to reasonable accommodation. This might include allowing someone time to declutter a home and seek therapy before forcing them to leave their home.
But as outlined in the Senate aging committee’s report, a lack of resources limits efforts to carry out these accommodations.
Hoarding is difficult to treat. In a 2018 study led by Ayers, the UCSD psychiatrist, researchers found that people coping with hoarding need to be highly motivated and often require substantial support to remain engaged with their therapy.
The challenge of sticking with a treatment plan is exacerbated by a shortage of clinicians with necessary expertise, said Janet Spinelli, the co-chair of Rhode Island’s hoarding task force.
Could Changes to Federal Policy Help?
Casey, the former Pennsylvania senator, advocated for more education and technical assistance for hoarding disorder.
In September, he called for the Substance Abuse and Mental Health Services Administration to develop training, assistance, and guidance for communities and clinicians. He also said the Centers for Medicare & Medicaid Services should explore ways to cover evidence-based treatments and services for hoarding.
This might include increased Medicare funding for mobile crisis services to go to people’s homes, which is one way to connect someone to therapy, Spinelli said.
Another strategy would involve allowing Medicaid and Medicare to reimburse community health workers who assist patients with light cleaning and organizing; research has found that many who hoard struggle with categorization tasks.
Williams, of Fight the Blight, agrees that in addition to more mental health support, taxpayer-funded services are needed to help people address their clutter.
When someone in the group reaches a point of wanting to declutter their home, Fight the Blight helps them start the process of cleaning, removing, and organizing.
The service is free to those earning less than 150% of the federal poverty level. People making above that threshold can pay for assistance on a sliding scale; the cost varies also depending on the size of a property and severity of the hoarding.
Also, Spinelli thinks Medicaid and Medicare should fund more peer-support specialists for hoarding disorder. These mental health workers draw on their own life experiences to help people with similar diagnoses. For example, peer counselors could lead classes like Fight the Blight’s.
Bernadette and Sanford say courses like the one they enrolled in should be available all over the U.S.
To those just starting to address their own hoarding, Sanford advises patience and persistence.
“Even if it’s a little job here, a little job there,” he said, “that all adds up.”

What Mattress Is Best, By Science?
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
The Foundations of Good Sleep
You probably know the importance of good sleep for good health. If not, here’s a quick refresher:
- Why You Probably Need More Sleep
- How Sleep-Deprived Are You, Really?
- The 6 Dimensions Of Sleep (And Why They Matter)
You should also definitely check out this quite famous book on the topic:
Why We Sleep – by Dr Matthew Walker
What helps, to get that good sleep
We’ve covered this a little before too, for example:
- Safe Effective Sleep Aids For Seniors
- Sleep Better With Better Air
- How To Nap Like A Pro (No More “Sleep Hangovers”!)
How to level-up from there
One of the biggest barriers to good sleep for many people is obstructive sleep apea:
Healthier, Natural Sleep Without Obstruction!
We covered (in the above article) a whole lot of ways of mitigating/managing obstructive sleep apnea. One of the things we mentioned as beneficial was avoiding sleeping on one’s back, and this is something Mayo Clinic’s Dr. Somers agreed with:
Back Sleeping, And Sleeping Differently After 50
“But side-sleeping is uncomfortable”
If this is you, then chances are you have the wrong mattress.
If your mattress is too firm, you can get around it by using this “five pillow” method:

If your mattress is too soft, then sorry, you really just have to throw that thing out and start again.
The Goldilocks mattress
While different people will have different subjective preferences, the science is quite clear on what is actually best for people’s spines. As this review of 39 qualified scholarly articles concluded:
❝Results of this systematic review show that a medium-firm mattress promotes comfort, sleep quality and rachis alignment❞
~ Dr. Gianfilippo Caggiari et al.
Read in full: What type of mattress should be chosen to avoid back pain and improve sleep quality? Review of the literature
Note: to achieve “medium-firm” that remains “medium firm” has generally been assumed to require a memory-foam mattress.
How memory-foam works: memory-foam is a moderately thermosoftening material, designed to slightly soften at the touch of human body temperature, and be firmer at room temperature. This will result in it molding itself to the form of a human body, providing what amounts to personalized support for your personal shape and size, meaning your spine can stay exactly as it’s supposed to when you’re sleeping on your side, instead of (for example) your hips being wider meaning that your lumbar vertebrae are raised higher than your thoracic vertebrae, giving you the equivalent of a special nocturnal scoliosis.
It will, therefore, stop working if
- the ambient temperature is comparable to human body temperature (as happens in some places sometimes, and increasingly often these days)
- you die, and thus lose your body temperature (but in that case, your spinal alignment will be the least of your concerns)
Here’s a good explanation of the mechanics of memory foam from the Sleep Foundation:
Sleep Foundation | What is Memory Foam?
An alternative to memory foam?
If you don’t like memory foam (one criticism is that it doesn’t allow good ventilation underneath the body), there is an alterative, the grid mattress.
It’s very much “the new kid on the block” and the science is young for this, but for example this recent (April 2024) study that concluded:
❝The grid mattress is a simple, noninvasive, and nonpharmacological intervention that improved adults sleep quality and health. Controlled trials are encouraged to examine the effects of this mattress in a variety of populations and environments.❞
~ Dr. Heather Hausenblas et al.
Read in full: Effectiveness of a grid mattress on adults’ sleep quality and health: A quasi-experimental intervention study
However, that was a small (n=39) uncontrolled (i.e. there was no control group) study, and the conflict of interest statement is, well, interesting:
❝Heather A. Hausenblas, Stephanie L. Hooper, Martin Barragan, and Tarah Lynch declare no conflict of interest. Michael Breus served as a former consultant for Purple, LLC.❞
~ Ibid.
…which is a fabulous way of distracting from the mention in the “Acknowledgements” section to follow, that…
❝Purple, LLC, provided financial support for the study❞
~ Ibid.
Purple is the company that invented the mattress being tested. So while this doesn’t mean the study is necessarily dishonest and/or corrupt, it does at the very least raise a red flag for a potential instance of publication bias (because Purple may have funded multiple studies and then pulled funding of the ones that weren’t going their way).
If you are interested in Purple’s mattress and how it works, you can check it out here ← this is a link for your interest and information; not an advertisement or an endorsement. We look forward to seeing more science for this though, and echo their own call for randomized controlled trials!
Summary
Sleep is important, and while it’s a popular myth that we need less as we get older, the truth is that we merely get less on average, while still needing the same amount.
A medium-firm memory-foam mattress is a very good, well-evidenced way to support that (both figuratively and literally!).
A grid mattress is an interesting innovation, and/but we’d like to see more science for it.
Take care!

The Bates Method for Better Eyesight Without Glasses − by Dr. William Bates
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
This is a very popular book and method, albeit not a very new one. It was first published in 1920; self-published by Dr. Bates, as the American Medical Association (AMA) considered it quackery.
Of course, our understanding of eyesight has improved a lot in the past 100 years, so, with the benefit of an extra century of ophthalmological research, who was on the right side of history?
As it turns out, all of Dr. Bates’ ideas have been firmly disproven, and eyes simply do not work the way he thought they do (for example, he believed that rather than adjusting the lens for focus, the muscles around the eye elongate the eyeball; this absolutely is not how focusing works, and while how much those muscles squeeze the eye does vary depending on some physiological factors, there are no known exercises that can change them).
Nevertheless, for the interested, his techniques include such things as:
- putting pressure on one’s eyes with one’s hands (which can increase glaucoma risk)
- visualization, rather than actual viewing, of an eye chart (this is ironic, because the book cover promises that an eye chart is included; it is not; perhaps it was hoped that we would visualize it more vividly and thus see it?)
- sunning, which is not only directly looking at the sun, but also using a burning glass to increase the focus of the sunlight onto one’s eye (please do not do this under any circumstances)
His primary thesis in this work, though, is that eyesight problems of all kinds (from short- and long-sightedness, to more serious things like cataracts and glaucoma) are caused by the tension produced by reading books, so relaxation exercises are his prescription for this.
The style is characteristic of its era and then some; bold claims are made with no evidence, there are no references, and the text is (ironically, given his opinions on tension being produced by reading books) quite dense. It certainly doesn’t lend itself well to skimming, for example, because something critical can easily be buried in a wall of text of what is, honestly, mostly waffle.
Bottom line: if you’d like to improve your eyesight and reduce your dependency on glasses, then we absolutely cannot recommend this book, and would direct you instead to Vision for Life, Revised Edition – by Dr. Meir Schneider, which is much more consistent with actual science.
Click here if you are, nonetheless, curious about Dr. Bates’ book and wish to check it out!
PS: Dr. Bates certainly was an interesting fellow; he disappeared mysteriously, but was found working as a medical assistant a few weeks later by his wife, whom he now claimed to not recognize. Then he disappeared again two days later (his wife never found him, this time, despite trying for many years), only to show up again, 13 years later, shortly after his wife’s death, whereupon he remarried (to his long-time personal assistant). None of this has anything to do with his fascinating opinions on eyesight, but it’s a story worth mentioning.

The Biological Mind – by Dr. Alan Jasanoff
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
How special is our brain? According to Dr. Alan Jasanoff, it’s not nearly as special as we think it is.
In this work, he outlines the case for how we have collectively overstated the brain’s importance. That it’s just another organ like a heart or a kidney, and that who we are is as much a matter of other factors, as what goes on in our brain.
In this reviewer’s opinion, he overcorrects a bit. The heart and kidneys are very simple organs, as organs go. The brain is not. And while everything from our gut microbiota to our environment to our hormones may indeed contribute to what is us, our brain is one thing that can’t just be swapped out.
Nevertheless, this very well-written book can teach us a lot about everything else that makes us us, including many biological factors that many people don’t know about or consider.
Towards the end of the book, he switches into futurist speculation, and his speculation can be summed up as “we cannot achieve anything worthwhile in the future”.
Bottom line: if you’ve an interest in such things as how transplanting glial cells can give a 30% cognitive enhancement, and how a brain transplant wouldn’t result in the same us in a different body, this is the book for you.
