My neighbor Charlie used to walk his dog every morning at six sharp. Then one Tuesday, I noticed him still in his bathrobe at noon. When I asked if everything was okay, he brushed it off. “Just tired,” he said.

Three months later, his daughter discovered he hadn’t paid his electric bill in half a year.

1) Managing their finances properly

This one hits close to home because I’ve seen it happen to people I’ve known for decades.

Financial difficulties may be one of the first noticeable signs of cognitive decline, yet families often miss it because bills get paid automatically or someone else handles the paperwork.

The warning signs aren’t always obvious. Your dad might start taking longer to balance his checkbook. Your mom might seem confused about a medical deductible she’s understood for years. They might make uncharacteristic purchases or forget to file their taxes.

I remember when my friend Tom, a former accountant, suddenly couldn’t calculate a tip at our usual diner. His wife laughed it off at first, but six months later they discovered he’d been making costly investment mistakes.

Research analyzing credit reporting and Medicare data found that in the five years before a dementia diagnosis, a person’s credit scores may start to weaken and payment delinquencies rise.

The challenge? Most people in their seventies guard their financial independence fiercely. They don’t want their kids poking around in their bank statements, and honestly, who can blame them?

But keeping an eye out for unopened mail, missed payments, or unusual spending patterns could prevent serious problems down the road.

2) Driving safely

This is a tough one because giving up driving feels like losing your freedom.

I’ve been fortunate to maintain my license, but I’ve started limiting my nighttime driving. The glare from oncoming headlights just isn’t what it used to be.

According to the Centers for Disease Control and Prevention, 20 older adults are killed and approximately 540 are injured in motor vehicle crashes each day.

The problem is that many folks don’t recognize when their driving has become unsafe. They might start drifting between lanes, missing stop signs, or getting confused in familiar areas. New dents on the car or scraped mailboxes tell a story that the driver themselves might not see.

What makes this especially tricky is that cognitive decline can affect judgment before it affects memory. Someone might genuinely believe they’re driving just fine when they’re actually creating dangerous situations.

My advice? If you notice your loved one hesitating at green lights, braking suddenly without cause, or expressing unusual anxiety about driving, it’s time for a conversation.

3) Keeping up with personal hygiene

I’ll be honest: this one makes me uncomfortable to discuss, but it’s too important to ignore.

When someone you love starts neglecting basic grooming, it’s rarely because they’ve stopped caring. Often, physical issues like arthritis can make tasks like opening shampoo bottles or reaching to wash their feet genuinely difficult.

But there’s more to it than that. As we age, our sense of smell diminishes. What’s obvious to you might be completely unnoticeable to them.

I’ve also seen friends withdraw from bathing because they’re afraid of falling in the shower. One slip can create a fear that lasts for months. Others struggle with the physical exhaustion that comes from standing long enough to bathe properly.

Depression plays a role too. When you’re feeling low, basic self-care can feel like climbing a mountain.

The key is addressing this with dignity. Nobody wants their children pointing out that they smell or that their clothes are dirty. But ignoring it can lead to skin infections and other health complications.

4) Maintaining their social connections

Last month at the hardware store, I ran into an old colleague I hadn’t seen in years. When I asked why he’d stopped coming to our monthly lunch group, he just shrugged. “Too much hassle,” he said.

That “too much hassle” is often code for something deeper.

Social isolation and loneliness in older adults have been linked to poorer cognitive function and higher risk for dementia, including Alzheimer’s disease.

The withdrawal happens gradually. First, they decline one invitation because they’re tired. Then they skip their book club because parking is difficult. Before long, they’ve stopped going anywhere at all.

Physical issues play a role. Hearing loss makes conversations exhausting. Vision problems make driving to social events challenging. Incontinence issues create anxiety about being away from home.

Emotional factors matter too. After losing a spouse or close friends, social settings can feel painful. The energy required to “put on a happy face” just isn’t there anymore.

What families don’t always realize is that this isolation creates a vicious cycle. The less someone socializes, the more difficult socializing becomes.

5) Engaging in hobbies and activities they once loved

I’ve painted model trains since I was a kid, and I can’t imagine a week without spending time in my workshop. But I’ve watched friends slowly abandon hobbies that once brought them joy.

My neighbor used to tend the most beautiful rose garden on our street. Then one summer, the roses went untended. “My back just can’t handle it anymore,” she told me.

Withdrawal from hobbies and interests can be subtle, with people finding excuses for not doing these activities or simply not enjoying them like they used to.

Here’s what’s concerning: hobbies often provide more than just entertainment. They offer structure, purpose, and social connection. When someone stops gardening, painting, or going to their chess club, they lose all three.

Physical limitations can be the culprit. Arthritis makes knitting painful. Poor vision makes reading difficult. Cognitive changes also play a role—the steps involved in a familiar hobby suddenly feel overwhelming.

But losing these activities often signals something more serious than just getting older. It can indicate depression, early cognitive decline, or simply giving up on finding joy in daily life.

6) Eating regular, nutritious meals

When I stopped by my friend Bill’s house last spring, I noticed his fridge was nearly empty except for some expired yogurt and a carton of milk.

“I’m just not hungry these days,” he said. But after some gentle prodding, he admitted cooking for one felt pointless, and standing at the stove made his legs ache.

Significant weight loss or gain, skipping meals, or forgetting to eat could suggest dementia, where seniors may forget to eat or prepare meals, or depression, which can cause loss of appetite.

The warning signs aren’t always dramatic. Maybe they’re eating the same simple meal every day because preparing anything else feels like too much work. Maybe they’ve started relying heavily on delivery or processed foods because cooking has become too complicated.

I’ve noticed this pattern in several friends: breakfast gets skipped because there’s no morning hunger. Lunch becomes minimal because preparing something feels like too much effort. By dinner, they’re too tired to cook anything substantial.

Before you know it, they’ve lost fifteen pounds and their doctor is concerned about malnutrition.

7) Taking their medications correctly

This one terrifies me because the consequences can be so serious.

My sister managed our mother’s medications during her final years, and she discovered Mom had been taking her blood pressure medication twice a day instead of once. Mom insisted she was following the instructions, but she simply couldn’t remember what the doctor had told her.

Medication mismanagement can have life-threatening consequences, especially for seniors on blood pressure or blood-thinning medications.

The problem isn’t always forgetting to take pills. People sometimes take them twice because they can’t remember their morning dose. Other times, they stop taking medication because they don’t understand why they need it or because the side effects bother them.

I use a pill organizer now, and I’ll admit it took some getting used to. Felt like admitting I was losing my grip. But it’s better than the alternative.

8) Keeping their home maintained

There’s a difference between a little clutter and a genuine problem. When I visit friends and see piles of unopened mail, spoiled food in the fridge, or basic repairs that haven’t been done for months, I worry.

A noticeable decline in housekeeping, difficulty preparing meals, or issues with medication management can indicate a lapse in their ability to care for themselves.

The house might have always been their pride and joy, but suddenly the lawn isn’t being mowed, dishes pile up in the sink, and the bathroom hasn’t been properly cleaned in weeks.

Physical limitations explain some of this. My back isn’t what it used to be, and I’ve had to hire someone to help with heavier cleaning. There’s no shame in that.

Cognitive issues or depression can also be behind the change. When someone who was always meticulous suddenly lives in chaos, something has shifted.

The challenge is that many people become defensive about their living situation. They don’t want their children thinking they can’t manage on their own.

9) Asking for help when they need it

This might be the most dangerous habit of all.

We grew up in a generation that prided itself on independence. Asking for help felt like admitting defeat. But this stubborn self-reliance can turn minor problems into major crises.

Many older adults take great pride in being able to manage their own affairs and make their own decisions, but this desire for independence can sometimes contribute to social detachment and isolation.

I see it all the time. A friend falls but doesn’t tell anyone because they don’t want to worry their kids. Someone struggles with their taxes but won’t ask for help because they’ve always handled it themselves. Another person feels dizzy frequently but doesn’t mention it to their doctor.

The mindset is understandable. We don’t want to be a burden. We don’t want our children hovering over us or questioning our judgment. We certainly don’t want to end up in a nursing home because we admitted we couldn’t manage everything perfectly.

But here’s what I’ve learned: asking for help early, when problems are still small, is what keeps us independent longer.

Final thoughts

I’m not sharing this to scare anyone or to suggest we all need constant monitoring. Most of us in our seventies are doing just fine, thank you very much.

But I’ve lost enough friends to know that these small changes matter. The neighbor who stopped answering his phone. The poker buddy who withdrew from our weekly game. The colleague who couldn’t follow the conversation anymore.

In almost every case, someone noticed something was off. But they didn’t want to interfere, didn’t want to hurt feelings, or convinced themselves it was “just getting older.”

If you’re worried about someone you love, trust your instincts. Have the uncomfortable conversation. Offer specific help rather than vague “let me know if you need anything” statements.

And if you’re the one in your seventies reading this? Consider letting people help occasionally. It doesn’t make you weak or dependent. It makes you wise enough to know that we all need each other sometimes.

That’s not getting old. That’s being human.
