Part 2 of a two-part series on making decisions about driving as we age. Read Part 1 here. 

It’s a simple but unfortunate fact: driving skills can wane over time.

Eventually, driving can become unsafe for an older driver, their passengers, and others on the road. If you notice a decline in driving abilities in a loved one, or in yourself, what’s the best way to handle this?

If you’re an older driver: Create an action plan

If you’re an older driver, don’t wait for a near-miss or an accident to think about the next steps. Planning ahead can help you tackle fixable issues, make necessary transitions easier, and avoid harming yourself or someone else.

Here are six measures you can take right now:

Have a frank conversation with a trusted friend or family member. After driving with them as a passenger, ask whether they are worried about your driving. Don’t disregard their comments, even if they share things you don’t want to hear.

See your doctor and talk about your driving. Is it harder to see at night? Are you finding you’re slower to react? Ask your doctor about medical care that can help, such as cataract surgery, treatment for sleep apnea, or adjustments to medications that might affect driving.

Take a self-evaluation test or an on-road test.AAA has tools to help with this, or you can check with your local department of motor vehicles for options. Even if you feel it’s unnecessary, a driving test can be reassuring to your loved ones that you’re still safe behind the wheel.

Take driving classes. In many places, there are general refresher courses, courses for defensive driving, and even simulators that don’t require actual road tests. AAA and AARP offer online courses that can help you improve your driving. (And by the way, these courses may also reduce the cost of your auto insurance!)

Consider alternatives to how you drive. Stick to roads that are close to home or to routes that have traffic lights (rather than having to decide when traffic is clear enough to turn). Consider giving up night driving if that is particularly difficult.

Make adjustments to your car that can help. Examples include using a steering wheel cover to improve your grip or changing the position of your seat to improve your view of the road. Check out the CarFit program that aims to optimize the “fit” of a driver in their car.

In addition, explore options that don’t require you to drive as often or at all:

• grocery delivery
• public or senior transportation (if offered or available where you live)
• carpooling with friends or family
• ride-hailing services or taxis
• hiring a driver.

Cost and availability may be barriers, but it’s worth looking into these options.

If you’re a concerned family member or friend: Start a conversation

With so much at stake, the language you use matters. So, it’s a good idea to think ahead about how to talk about these challenges.

Put safety and solutions first. It’s best not to lead by criticizing driving skills. Instead, talk about driving with safety and solutions in mind, such as the options described above.

Choose your words carefully. It helps to avoid threats or confrontational language: rather than saying “Your driving is terrible so I’ve taken away your keys,” focus on safety and support:

•  
• Let’s talk about how I can help so you don’t have to drive. I can drive you to get your groceries on Sundays and we can make a day of it!
• How do you think those dents got on your car? Are you having trouble with your vision?
• We’d all feel terrible if you had an accident and got hurt or hurt someone else.

Offer to go for a ride together and then to talk about specific concerns, such as staying in the proper lane, changing lanes, making left-hand turns, speed, or sudden braking. Encourage consideration of a self-evaluation or on-road test, and driving classes to help polish skills.

Use examples from familiar experiences. It can be helpful to remind your loved one how his or her parents or grandparents had to cut back on their driving, or how an older neighbor was an unsafe driver.

Focus on the risks posed by other drivers. Aggressive or unpredictable drivers can pose more danger to older drivers with slower reaction times.

How else can families or friends of older drivers be helpful?

• Consider whether to contact their doctor. Ask their doctor if it’s possible to talk with your loved one or friend about their driving. State regulations vary on mandatory reporting of conditions that affect a patient’s ability to drive. Be aware that some doctors may be reluctant to report their patients to their registry of motor vehicles, due to concerns about patient privacy or jeopardizing the patient-doctor relationship.
• Look into rules and regulations around older drivers where your loved one lives. Illinois is currently the only state that requires a road test for older drivers. But many states require vision tests and in-person renewal with increasing frequency for older drivers.
• Consider reporting an unsafe driver to traffic safety authorities. This may feel like a betrayal, but if other efforts have failed this option might be better than waiting until there’s a serious accident.

The bottom line

In the future, safe, driverless cars may be a solution to the challenge of waning driving skills among older drivers. But we’re not there yet.

Right now, we should all acknowledge that it’s not easy to address concerns about impaired older drivers. My best advice is that older drivers and their loved ones try to talk about ways to remain a safe driver and put a plan in place. Ideally, we all would start the conversation well before any driving problems are evident.

And it may take more than one conversation. Many more. But let’s face it: sooner or later, most drivers will have to stop driving. For some older drivers, that time may be now. For the rest of us, recognizing this eventuality could help when our time comes.

The news these days is overwhelming in its awfulness. Acts of terrorism, wars, and heated conflicts constantly erupt throughout the world. Climate change looms, contributing to wildfires and flooding. Incomprehensible shootings occur with numbing regularity. The pandemic seems to be shifting from an immediate threat to health to an endemic illness — yet it’s still affecting us. The news has been so horrible, and so unrelenting, that it is hard to even process it.

Imagine processing it as a child?

Our first instinct is usually to shelter our children from the news and not say anything about it to them at all. That’s completely understandable, and if your child is very young or you are certain for some other reason that they aren’t going to hear about it, then not saying anything is a viable option.

But if they aren’t very young, or if you ever have the news on where they can see, or if they are ever in settings where people might have the news on or talk about it, it might not be so viable. If children are going to hear about something, they really should hear about it from you.

Also, as parents it’s important that we give our children the perspective and skills they need to navigate this scary world where, let’s be honest, bad things happen. The way you talk to children about tragedies in the news can help them cope not just now, but in the future.

The American Academy of Pediatrics has all sorts of resources to help parents talk with children about tragedies. Here are four simple things all parents can and should do:

1. Tell them what happened, in simple terms. Be honest, but skip the gory details. Answer their questions just as simply and honestly. If you think — or know — that your child has already heard something, ask them what they’ve heard. That way you can correct any misinformation, and know not only what you need to explain but also what you may need to reassure them about.

2. Be mindful of the media that your child sees. The news can be very graphic, and because the media are as much in the business of gaining viewers as of delivering news, they tend to make things as dramatic as possible and play footage over and over again. When the planes flew into the Twin Towers on 9/11, my husband and I were glued to the television, not realizing that one of our daughters, who was 3 years old at the time, thought that planes were literally flying into buildings again and again. It wasn’t until she said, “Are those planes going to come here too?” that we shut off the TV and didn’t turn it back on again until all the children were in bed.

3. Make sure your child knows that you and others are always doing everything you can to keep them safe. Talk about some of the ways you keep them safe, ways that are relevant to the tragedy you are talking about. Make a safety plan as a family for things like extreme weather or getting separated. Help them think about what they might do if they are ever in a scary situation, and who they could turn to for help. Which leads me to the most important thing to do…

4. Look for the helpers. The wonderful Fred Rogers often talked about how when he saw scary things on the news, his mother would tell him to look for the helpers, because there are always people who are helping. That may be the best thing we can do as parents: help our children look for the helpers. In all of the recent tragedies, as in all tragedies, there were so many helpers and heroes. When we concentrate on those people, not only do we give our children hope, but we may empower them to one day be helpers too.

The world can be a scary place, yet there is much we can do — from a very young age — to help children build strengths and nurture resilience, even in the face of tragedy.

Childbirth — painful, messy, unpredictable — has been part of humankind for time immemorial. And in the US, which has surprisingly high rates of avoidable complications and maternal deaths, more people seem to be seeking out doulas for additional care during pregnancy and birth, says Natalia Richey, interim chief midwife in the Department of Obstetrics and Gynecology at Massachusetts General Hospital.

Some research suggests that doula care may benefit both mother and baby. But what does a birth doula do? While neither a midwife nor a doctor, a professional doula can provide emotional and physical support to women during pregnancy and throughout the birthing process.

Here’s what to know if you’re considering doula care.

What’s the difference between doulas and midwives?

Midwives and doulas tend to have a few overlapping duties. But there’s a key difference: midwives provide medical care and doulas don’t.

• Midwives: Their primary responsibility is to maintain the physical health of a woman and her baby throughout childbirth. Certified nurse-midwives like Richey are also trained nurses, but most midwives have undergone some type of medical training. This may vary depending on state laws.
• Doulas: Unlike midwives, doulas don’t perform any medical tasks. Their main role is to help laboring women remain comfortable and calm using various methods, including suggesting comfort measures and optimal positions for labor and pushing.

“Many women hire doulas if they’re trying to have an unmedicated birth,” Richey says. “Doulas are really good at knowing what techniques — such as walking, showering, massage, or aromatherapy — can help a woman through the pain. It’s like having a coach.”

Are doulas trained or licensed?

Be aware that doula training varies widely. There are no formal rules requiring licensing or certification. Many doulas, however, seek certification from the more than 100 independent organizations that offer some type of doula training and credentials, according to the National Health Law Program.

Is doula care covered by insurance?

Private insurers often do not cover doula care, which can cost several thousand dollars when arranged for privately.

However, some employers — including Walmart — will help pay for doula care. And some hospital systems, particularly in low-income or medically underserved areas, have doula programs aimed at improving maternal care during and after pregnancy. Others may arrange doula support for people with limited resources who might otherwise be alone during the later stages of pregnancy and birth.

As of February 2023, 10 states and the District of Columbia provided Medicaid coverage for doula services. Other states are in the midst of implementing coverage. Most of the states that provide Medicaid coverage for doula care require doulas to be trained or certified by an approved organization.

Can working with a doula improve birth outcomes?

A 2023 analysis in the journal Cureus reviewed 16 individual studies done over 22 years. It found doula support was linked with better birth outcomes, such as fewer C-sections and premature deliveries, and shorter length of labor.

Additionally, the emotional support provided by doulas was associated with less anxiety and stress in birthing mothers. Among low-income women, doula support was shown to improve breastfeeding success.

“It’s impressive,” Richey says. “I think those improved outcomes are due to having an expert in the labor process who isn’t a medical person but is just there for you from moment to moment.”

How do people collaborate with doulas?

Agreements about care vary. Typically, doulas meet with women every few months through their pregnancy to discuss their goals for birth (such as skipping pain medication, for example), and to build rapport with both the expectant person and their spouse or partner.

Like obstetricians, doulas are on call 24/7 to support clients who have gone into labor or who have their labor induced. Doulas stay throughout the birth process.

“Having someone there who’s seen quite a few births, who can support and advocate for them, can be a huge comfort,” says Richey.

This may be especially important to women with limited resources, particularly those who might otherwise be alone during the later stages of pregnancy and birth. “Doulas remind women that they’re okay and can get through this process — all the things many of us take for granted,” Richey says.

How might a doula work with the OB/GYN team?

Usually, this is a seamless process, Richey says. If a hospital arranges for a woman’s doula, OB/GYN team members may meet the doula a couple of times before childbirth. Meanwhile, a doula who’s been hired privately will usually only meet the larger OB/GYN team when the woman arrives at the hospital to give birth.

When everyone sticks to their assigned roles, all goes smoothly. For a doula, that may mean suggesting nonpharmacological ways to ease pain and help labor progress. Boundaries are important, though, when medical intervention is needed.

“If the baby’s heart rate is down, for instance, the expertise needs to be left to the midwife or doctor,” Richey explains.

What questions should you ask if you’re interested in working with a doula?

Richey suggests starting by asking yourself:

• What are my hopes and goals for the childbirth process? Might a doula enhance my ability to achieve them?
• How do I envision my support team during delivery? Do I have a partner, a mom, or a friend I want there? Would a doula add to any support I already have?
• Do I have friends or family members who have used doulas in the past? What were their impressions of the experience? Can they recommend a doula?

If you contact a doula to explore your options, ask about:

• their training and certification
• how many births they’ve attended
• how they believe they can help you during your pregnancy and during labor
• how they will collaborate with your partner or spouse and the medical team
• whether they provide support after a birth — if so, what type of support and for how long?

“Take the time to meet with any doula you’re considering and make sure they’re a good fit,” Richey advises, “because this is someone who will be there during one of the most vulnerable times of your life. Having someone there who doesn’t make you feel safe and comfortable can affect birth in a major way.”

It’s no secret that the typical American diet isn’t very healthy. Only about one in 10 American adults eats the recommended daily amount of fruit (1-1/2 to 2 cups) or vegetables (2 to 3 cups). These dietary shortfalls are even more pronounced among people in lower income groups. And the health impacts are substantial: In the United States, poor diets have been linked with more than 300,000 annual deaths from heart disease and diabetes.

Produce prescriptions enable health care workers to give vouchers for free or discounted produce at grocery stores or farmers’ markets to people living in low-income neighborhoods. A recent study asks whether these programs might help people at risk for heart disease eat more fruits and vegetables, and possibly improve health issues like high blood pressure. While Dr. Anne Thorndike, an associate professor of medicine at Harvard Medical School who studies cardiometabolic disease prevention and nutrition security, questions some findings in the study, she notes that there are lessons to be learned here.

How was the study done?

The study pooled data on nine different produce prescription programs given out in 22 locations spread over a dozen states across the country. A total of about 2,000 adults and 1,800 children from low-income neighborhoods were enrolled. Participants received vouchers or cards to buy produce worth $15 to $300 per month (depending on family size). They also attended nutrition classes.

The programs lasted between four and 10 months. At the start and end of each program, participants filled out questionnaires about their fruit and vegetable consumption and health status. The questionnaires also asked about food insecurity, which is not having access to adequate food to meet one’s basic needs. Blood pressure, blood sugar, height, and weight were recorded for some program participants.

What were the findings?

During the produce prescription program, adults ate nearly one additional cup of fruits and vegetables per day; children ate an extra quarter-cup daily. In adults, these changes were associated with lower blood pressure in people who had high blood pressure and lower blood sugar in people who had diabetes. The researchers also documented drops in body mass index (BMI) among adults with obesity.

All glowing results, right? Well, maybe not.

“Because of the study’s limitations, including a lack of a comparison group — which is standard practice in diet studies — those potential health benefits are hard to prove,” says Dr. Thorndike. In addition, the investigators relied on statistical techniques to account for high rates of missing data from some programs, which could also skew results.

It’s hard to imagine how eating an extra serving of produce daily could lower BMI values within six months, says Dr. Thorndike. “However, there’s so much strong data that associates eating a healthy diet, particularly one that includes plenty of fruits and vegetables, with a lower rate of almost every chronic disease, including heart disease, cancer, and dementia,” she adds.

The bottom line

While flawed, this research is interesting, and highlights the need to improve diet quality for all Americans, especially those who face added barriers due to their financial circumstances.

“I’m a huge believer in produce prescriptions,” says Dr. Thorndike, “and part of my research mission is to determine the best way to design and deliver them so people get the greatest possible health benefit.”

The study also helps raise awareness about food insecurity, which affects about one in 10 American households. At the start of the study, more than half of the households participating reported food insecurity. Among all the participants, reported rates of food insecurity dropped by one-third by the end of the program compared to the start.

“We all need to acknowledge that many people are less healthy because they can’t get access to or afford the foods they need to prevent or treat disease,” Dr. Thorndike says. Broadening the focus beyond produce to “prescribe” other types of healthy foods, such as whole grains and lean proteins, may be another helpful solution, she adds.

When I took up running in college, a friend of mine scoffed at the idea. He hated running and was convinced runners were “wearing out” their joints. He liked to say he was saving his knees for his old age.

So, was he onto something? Does running really ruin your joints, as many people believe?

Runners can get arthritis, but is running the cause?

You may think the answer is obvious. Surely, years of running (pounding pavements, or even softer surfaces) could wear out your joints, much like tires wear out after you put enough miles on them. And osteoarthritis, the most common type of arthritis, usually affects older adults. In fact, it’s often described as age-related and degenerative. That sounds like a wear-and-tear sort of situation, right?

Maybe not. Sure, it’s easy to blame running when a person who runs regularly develops arthritis. But that blame may be misguided. The questions to ask are:

• Does running damage the joints and lead to arthritis?
• Does arthritis develop first and become more noticeable while running?
• Is the connection more complicated? Perhaps there’s no connection between running and arthritis for most people. But maybe those destined to develop arthritis (due to their genes, for example) get it sooner if they take up running.

Extensive research over the last several decades has investigated these questions. While the answers are still not entirely clear, we’re moving closer.

What is the relationship between running and arthritis?

Mounting evidence suggests that that running does not cause osteoarthritis, or any other joint disease.

• A study published in 2017 found that recreational runners had lower rates of hip and knee osteoarthritis (3.5%) compared with competitive runners (13.3%) and nonrunners (10.2%).
• According to a 2018 study, the rate of hip or knee arthritis among 675 marathon runners was half the rate expected within the US population.
• A 2022 analysis of 24 studies found no evidence of significant harm to the cartilage lining the knee joints on MRIs taken just after running.

These are just a few of the published medical studies on the subject. Overall, research suggests that running is an unlikely cause of arthritis — and might even be protective.

Why is it hard to study running and arthritis?

• Osteoarthritis takes many years to develop. Convincing research would require a long time, perhaps a decade or more.
• It’s impossible to perform an ideal study. The most powerful type of research study is a double-blind, randomized, controlled trial. Participants in these studies are assigned to a treatment group (perhaps taking a new drug) or a control group (often taking a placebo). Double-blind means neither researchers nor participants know which people are in the treatment group and which people are getting a placebo. When the treatment being studied is running, there’s no way to conduct this kind of trial.
• Beware the confounders. A confounder is a factor or variable you can’t account for in a study. There may be important differences between people who run and those who don’t that have nothing to do with running. For example, runners may follow a healthier diet, maintain a healthier weight, or smoke less than nonrunners. They may differ with respect to how their joints are aligned, the strength of their ligaments, or genes that direct development of the musculoskeletal system. These factors could affect the risk of arthritis and make study results hard to interpret clearly. In fact, they may explain why some studies find that running is protective.
• The effect of running may vary between people. For example, it’s possible, though not proven, that people with obesity who run regularly are at increased risk of arthritis due to the stress of excess weight on the joints.

The bottom line

Trends in recent research suggest that running does not wear out your joints. That should be reassuring for those of us who enjoy running. And if you don’t like to run, that’s fine: try to find forms of exercise that you enjoy more. Just don’t base your decision — or excuse — for not running on the idea that it will ruin your joints.
