At 83, my doctor looked at my latest test results and shook his head. My blood pressure, cholesterol, heart rhythm, memory, even bone density—all better than many of his 60-year-old patients. He told me he’d never seen anything like it. Then I explained how I live, and he was even more surprised.
Because the truth is, most of what I do every day are things doctors used to call bad habits. But new science from Harvard, Tufts, and the National Institute on Aging says the opposite. These so-called bad habits are keeping me strong, sharp, and active. Here are the five that work for me.
Habit number one: taking a daily afternoon nap. For years, I felt guilty every time I closed my eyes in the afternoon. Society told us only lazy people or children nap. Strong adults push through the slump.
So I fought it, drank more tea, went for walks, distracted myself with chores. But around 1 or 2 p. m. , that heavy wave of tiredness always hit.
Eventually, I stopped fighting. I gave myself permission to lie down for 30 to 45 minutes every afternoon. The change was extraordinary. My mind became clearer, my evenings calmer, and that post-lunch fog disappeared.
Harvard Medical School did a long-term study on thousands of older adults and found that seniors who nap 30 to 60 minutes daily have a 37% lower risk of heart disease than those who never nap. That tiredness isn’t weakness—it’s our natural circadian rhythm signaling a need for a break. When we ignore it, we stress the cardiovascular system and overload the brain. But a nap resets everything.
During those 30 to 60 minutes, your brain organizes memories, stress hormones drop, and your heart recovers. The National Institute on Aging also found that afternoon naps improve memory, attention, and emotional control. A friend of mine, Estelle, 77, avoided naps for years because she thought it made her look old. After she started napping 45 minutes daily, her mental fog lifted, and she felt human again in the evenings.
Her grandkids noticed she was more patient and playful. The secret is timing and duration. Too long—more than 90 minutes—or too late in the day can interfere with nighttime sleep. The sweet spot is between 1 and 3 p.
m. , when your body temperature and alertness naturally dip. Make your environment calm and dark, lie down, and set a gentle alarm. And don’t feel guilty.
There’s no medal for forcing yourself to stay awake. Every other creature follows its natural rest cycle except humans. If your body tells you it needs to pause, that’s not laziness. It’s intelligence.
Habit number two: eating full-fat dairy every day. For decades, we were told fat is the enemy. Doctors, magazines, and ads all said fat clogs arteries, fat makes you fat. Avoid butter, drink skim milk, eat low-fat yogurt, use margarine.
We filled our carts with fat-free everything. But when manufacturers removed the fat, they replaced it with sugar, starch, and chemicals to make it taste good. Instead of getting healthier, people got sicker. Obesity, diabetes, and heart disease skyrocketed.
About 10 years ago, I decided to go against that old advice. I switched back to whole milk, full-fat Greek yogurt, and real butter. My blood sugar stabilized, my energy improved, and my test results stayed consistent. A major study from Tufts University followed more than 3,000 seniors for 15 years and found that those who ate full-fat dairy had a 42% lower risk of developing type 2 diabetes than those who stuck to low-fat or non-fat versions.
The fat in dairy helps your body absorb fat-soluble vitamins A, D, E, and K, which are crucial for your heart, brain, and immune system. Without fat, those vitamins pass through unused. Full-fat dairy also helps regulate blood sugar by slowing digestion, preventing spikes and crashes. It contains conjugated linoleic acid, a natural fatty acid that may protect against heart disease and certain cancers.
Your brain, which is nearly 60% fat, depends on these nutrients. A friend, Terrence from St. Louis, spent 30 years on a low-fat diet. He was constantly hungry, snacking all day, and his blood sugar was a mess.
When he switched to full-fat yogurt and milk, his sugar levels balanced within weeks. He felt satisfied for the first time in decades. Historically, humans have consumed full-fat dairy for thousands of years. The epidemics of diabetes and obesity only exploded after we started removing natural fat and replacing it with processed sugar.
So, if you see low-fat or fat-free on a label, replace it. Use real butter, whole milk, and real cheese. Don’t worry about calories—natural fat helps you feel full longer, so you eat less overall. And dietary cholesterol from foods like eggs and dairy doesn’t automatically raise your blood cholesterol.
That’s old science. What’s far more damaging are refined carbs and sugar. Enjoy your full-fat dairy without guilt. Fat isn’t your enemy.
It’s your ally. Habit number three: drinking regular coffee, 3 to 5 cups daily. For most of my life, I was told coffee would ruin my heart, raise my blood pressure, make me anxious, or wear out my body. Friends and even some doctors said I should quit.
But I loved coffee—the aroma, the warmth, the clarity it gives me in the morning. So I never stopped. I drink about 3 to 4 cups a day, real regular coffee, not decaf, not fancy powders, just freshly brewed black coffee with a splash of cream. The latest research says that choice may be one of the main reasons my brain is still sharp at 83.
A massive study from Johns Hopkins University followed tens of thousands of seniors for decades and found that those who drank 3 to 5 cups of coffee a day had a 65% lower risk of developing Alzheimer’s disease compared to those who rarely drank it. Coffee contains over a thousand bioactive compounds—antioxidants, polyphenols, and natural anti-inflammatory agents—that protect brain cells from damage that leads to dementia. Caffeine itself improves alertness, helps the brain store memories, and prevents the buildup of sticky proteins that cause Alzheimer’s. Research from Harvard Medical School shows coffee drinkers also have lower risks of type 2 diabetes, liver disease, certain cancers, and Parkinson’s disease.
A woman I know, Lever, 79, from Detroit, started drinking four cups of coffee daily after reading about its cognitive benefits. Two years later, her memory test results had improved. Her doctor was so surprised he asked what changed. She simply said, “Coffee.
” Of course, not everyone reacts the same way to caffeine. If you’re sensitive, adjust how much or when you drink it. For most people, stop drinking coffee by around 2 p. m.
so it doesn’t affect sleep. Avoid adding too much sugar or artificial sweeteners—they cancel out the health benefits. Add a splash of whole milk or cream instead. It smooths the flavor and helps your body absorb beneficial compounds.
But here’s the part most people don’t realize: it’s not just how much coffee you drink, it’s how you drink it. When you add sugar, flavored syrups, and whipped cream, it’s no longer the healthy drink research praises. I’ve been drinking my coffee black for most of my life, sometimes with a little cream or a pinch of cinnamon. That’s all you need to let the antioxidants do their work.
Compounds like chlorogenic acid help control blood sugar and reduce inflammation. Timing also matters. Drinking your first cup about an hour after waking up is better. When you first wake up, your cortisol is already high.
If you drink coffee immediately, it can interfere with that natural rhythm and make you more dependent on caffeine. But if you wait an hour, your body and the coffee work together. And don’t fear moderate caffeine. Studies show that for most people, 3 to 5 cups a day—about 300 to 400 mg—is perfectly safe.
It might just be one of the most beneficial habits you can have in your 70s or 80s. So, the next time someone scolds you for having too much coffee, just smile. Tell them it’s your daily brain medicine. Habit number four: staying up late but sleeping deeply.
This one will surprise you and maybe even relieve you. If you’ve ever felt guilty for being a night owl, let that guilt go. For most of my life, I was an early riser because everyone said that was healthy. Early to bed, early to rise.
But once I hit my 70s, I couldn’t fall asleep early anymore. I’d lie in bed at 9 or 10 p. m. , staring at the ceiling, restless.
I used to feel frustrated, thinking something was wrong with me. Then one night, instead of forcing myself to sleep, I got up, made some tea, and watched a quiet documentary. I finally went to bed around midnight and woke up naturally at 7 a. m.
, feeling more refreshed than I had in years. So I started experimenting and realized something important: it wasn’t when I slept that mattered most, it was how well I slept. Recent research from the University of California has shown that quality sleep—deep, restorative sleep—is far more crucial to your health than the exact bedtime. Our sleep patterns change with age.
As we grow older, our circadian rhythm naturally shifts, and many of us become evening types. Forcing ourselves to sleep early when our body isn’t ready can actually make sleep worse—more tossing and turning, more light sleep, less recovery. Now, I go to bed when my body tells me to, usually around 11:30 or midnight, and wake up about 7 hours later. I focus on making those 7 hours deep and undisturbed.
I keep my room cool, turn off all screens an hour before bed, and listen to calming music or nature sounds. My sleep tracker shows that my deep sleep percentage is higher now than it was when I was 65. I met a retired nurse named Evelyn, 82, who used to feel the same guilt. She forced herself to go to bed at 9 p.
m. every night because she thought that’s what healthy people did. But she always woke up at 3 a. m.
and couldn’t fall back asleep. Once she let herself stay up until 11:30, her sleep became solid. No more middle-of-the-night frustration. Your body doesn’t run on someone else’s schedule.
If you’re productive and peaceful in the evenings, that’s fine. What really matters is keeping your routine consistent and ensuring your room environment supports deep sleep. Late-night hours can be incredibly healing for the mind. Those quiet moments after everyone else has gone to bed—when it’s just you, your thoughts, and a soft light—that’s when I reflect, write in my journal, or simply listen to my breath.
It’s my personal time, a kind of therapy. So, if you enjoy staying up late, don’t let others shame you. Just make sure you give your body the chance to rest deeply afterward. It’s not about being an early bird or a night owl.
It’s about being in tune with your own rhythm. Habit number five: laughing at myself every day. This is the most unexpected bad habit of them all. I laugh at my mistakes, my clumsiness, my forgetfulness, even the silly things I say.
Honestly, I think this one habit has done more for my health than any diet, supplement, or exercise routine. Most people think of laughter as something you do after you’re happy. But I’ve learned it’s the other way around. Laughter creates happiness.
It physically changes your body chemistry. When you laugh, even for 30 seconds, your brain releases endorphins—those feel-good hormones that relieve pain, reduce stress, and strengthen your immune system. There’s an old saying that laughter is the best medicine, and modern science agrees. Studies from the Mayo Clinic and University College London have shown that people who laugh regularly have stronger heart function, lower blood pressure, and improved immune response.
Laughter increases blood flow almost as much as light exercise. I try to find something funny in every situation. When I spill coffee on my shirt, I say, “Ah, my morning artwork. ” When I forget why I walked into a room, I chuckle and call it the mystery of the missing memory.
It might sound silly, but those tiny moments of humor transform stress into ease. There’s an 84-year-old man I know named Frank. He lost his wife 5 years ago and went through a long period of sadness. But one day he joined a local laughter yoga group—yes, it’s a real thing where people gather to laugh together for no reason.
Within months, his blood pressure went down, and he felt alive again. That’s the healing power of laughter. It keeps your spirit light, and when your spirit is light, your body follows. At my age, you can’t take yourself too seriously.
Life throws curveballs. Your body changes. Your plans shift. People you love come and go.
But if you can still find reasons to smile, to giggle at your own humanity, then you’re not just surviving—you’re thriving. So laugh at yourself a little more. Don’t scold yourself for forgetting things or slowing down. You’ve earned the right to live joyfully without judgment.
Laughter turns every wrinkle into a story and every mistake into a moment of grace. Now that you’ve heard my five bad habits—taking a daily afternoon nap, eating full-fat dairy, drinking regular coffee, staying up late but sleeping deeply, and laughing at myself every day—you might notice a pattern. None of these habits come from guilt, fear, or restriction. They all come from listening to my body, not fighting it.
Real health isn’t about punishing yourself or forcing your body into someone else’s rules. It’s about working with it, respecting its rhythms, its needs, its wisdom. After 83 years, I’ve learned that the more you let go of unnecessary control, the more naturally your body finds balance. When my doctor looked at my test results and said he was shocked, I told him the truth.
I don’t do anything extraordinary. I simply do the simple things that make me feel good—the things my body responds to with gratitude. I rest when I’m tired. I eat real food.
I drink what I enjoy. I sleep when I’m ready. I laugh as often as I can. Maybe that’s the biggest secret to staying young: not resisting life, but flowing with it.
So, if you’re in your 60s, 70s, or beyond, and you’ve been told it’s too late to change your habits, don’t believe that for a second. Sometimes the healthiest things you can do are the ones you were told not to do. Listen to your own rhythm. Trust your instincts.
Give yourself permission to enjoy life again—naps, coffee, late-night laughter, and all. Because the truth is, you don’t stay young by avoiding mistakes or following every health trend. You stay young by keeping your curiosity alive, your body rested, and your heart light.
And if that means breaking a few rules along the way, well, at 83, I’d say it’s worth it.
