Hey, hey, welcome back to Next Act Ninjas, the go-to podcast for mastering your health and wealth longevity. I'm your host, Rachael Van Pelt. Today, I'm going to ask you to shake things up a bit. Because that comfortable life you've worked so hard to secure, well, it just might be speeding up your biological clock. It's making you age faster.
Does that sound counterintuitive? I know by 50, 60, maybe 70, we feel like we deserve a little comfort in our life. And yet, emerging science says that nestling too snugly into routine, physically, mentally, or socially, it just sends this message to every cell in our body that it's "time to wind down". And yet, that's the last thing we want ourselves to do.
Think about it this way. Picture two 67-year-olds. One, spends most mornings scrolling the news, their afternoons tackling crossword puzzles, their evenings watching well-worn crime dramas. The other decides to learn salsa dancing, join a community choir despite not having ever sung on stage, and sprinkles hikes in on the weekends because those steep bits still feel a little years down the road, researchers would predict that that second person is going to have a younger brain, stronger muscles, nimbler blood vessels, and a more resilient immune system. The difference isn't a magic that they have sprinkled in, calculated novelty into their life.
Why does novelty keep us young? That's because inside every muscle, every organ, every brain cell lives a tiny power plant called the mitochondrion. When life gets a little challenging, your mitochondria receive a signal that more "power" is needed. They respond then by building additional "engines", cleaning out broken parts, and patching up DNA. Scientists call this response to mild stress "hormesis", but I like to call it cellular CrossFit training. Interestingly, in the brain, those same mini stress moments trigger housekeeping crews that sweep away damaged proteins that clog the brain's neural circuits. And that just sets the stage for sharper memory and better mood.
In other words, when we face manageable stress, whether that's physical, mental, or emotional, our bodies and brains respond by becoming stronger and more adaptable. Think about exercise. When you work out, it breaks down your muscle fibers temporarily, which causes mild stress. But in response to that stress, your body rebuilds stronger, healthier muscles. Similarly, when your brain is challenged, when you're learning a new skill or tackling a puzzle or navigating unfamiliar technology, it forms new neural pathways. And that just keeps cognitive decline at bay.
And your brain gets an extra bonus any time you do anything, even slightly unfamiliar. Say you learn a TikTok dance from your grandkids. Your brain floods itself with a growth fertilizer named BDNF. That fertilizer coaxes brand new baby neurons to sprout in your brain's memory hub. At the same time, a trickle of dopamine makes the entire experience feel rewarding, which is why you suddenly want to do more of it. You do it a few more times, and that just builds a self-reinforcing cycle of curiosity, pleasure, and confidence.
In fact, MRI scans reveal that older adults who routinely tackle brand new skills can grow fresh white matter highways in their brains. Those are the same tracks that normally would shrink in early stage dementia. So it turns out that the best insurance for your later life memory isn't the daily crossword, it's the mildly terrifying act of being a beginner again.
Research shows that adults who regularly push their boundaries and experience mild to moderate stress in a controlled purposeful way, they just age better. They have sharper cognition, healthier immune systems, and significantly less chronic disease.
Take Mark, for example. He was a 68-year-old widower who moved to be closer to his daughter, but he hadn't yet made much effort to connect to his new community. He found comfort day-to-day in his routine of doom scrolling, Netflix, and microwave meals. He had pre-diabetes and was starting to notice that he couldn't remember the names of his neighbors when he saw them on the street. But one night after watching a favorite stand-up comedian on HBO, he impulsively decided to sign up for a stand-up comedy workshop. Now, the first time that he went on stage, it left him sweaty-palmed, and of course, he felt silly in front of his classmates, but every week it got a little easier, even if it was a bit challenging. Six months later though, his blood sugar was better, his blood pressure was better. More importantly, his memory improved. He could easily memorize his long comedy routines and even remember his neighbor's names. Now this didn't happen because he ran out and bought some anti-aging supplement or diabetes meds. He simply traded a few hours of his passive comfort for more stimulating challenge.
Mark managed to get out of one of the big comfort zone traps that we call "social shrinkage". Humans are wired to be tribal and yet as we get older, our inner circle tends to shrink, doesn't it? And that's because forming new friendships feels uncomfortable. It requires awkward small talk and vulnerability. Unfortunately, that shrinking circle, it just leads to loneliness and raises our inflammation. So when you politely decline invitations or avoid meeting fresh faces, your immune system interprets that isolation as danger. And the result? Higher blood pressure, stickier cholesterol, slower wound healing. So keep thinking about ways you can expand your circle. Any group that meets regularly and tackles a shared goal is going to douse that inflammatory fire.
Another comfort zone trap is "intellectual inertia", also known as mental atrophy. Many of us joke that "I'm just not tech savvy", and then we hand our phone to the nearest teenager. And yet the physical brain thrives on techno-friction. Every time you wrestle with a new app or AI technology, your brain builds new neural networks that keep your memory humming. It's a little bit like adding extenders to your home Wi-Fi network.
In fact, one study showed that older adults who navigated 3D video games for just a few weeks, they grew a part of the brain called the hippocampus, and that's involved in memory formation, learning, and spatial navigation. In fact, the change in volume was comparable to that of college students. And so the next time you're struggling with that digital device or you're learning a new platform, pause before you call in one of your kids to do it for you. Google the solution, watch a tutorial, and just let those neurons "sweat" a bit.
Avoiding technology altogether just traps us even more. I know it might feel safer to pay bills by check or call the doctor's office for results, but the digital world isn't going away. Mastering telehealth portals or smart home sensors does more than protect your autonomy. The learning curve itself bathes your brain in novelty chemicals, which are great for bolstering motivation and mood.
Now the other comfort zone trap is simply "sedentary lifestyle". Even for those who worked fairly sedentary desk jobs, retirement results in fewer step counts. Unfortunately, fewer steps and more sitting quietly tells our muscles that they're no longer needed. When our muscles contract, it releases myokines. Those are the tiny proteins that sweep fat from the liver, calm inflammation, and spark new brain cells. When you skip those contractions, you skip the medicine. So try to sneak movement in wherever you can. Our bodies, they were made to move, and every little bit, it really does count. Even the mini dance parties in the kitchen while you wait for water to boil. Don't overthink it, just move.
But sitting isn't the only physical comfort trap. Our bodies also get overly used to temperature-controlled environments and constant food availability. That's why challenging things like cold plunges and intermittent fasting can be great mini stressors for the body. They are easy ways for you to create what we call "productive discomfort" in your life. A 30 second cold shower jolts your body with a burst of noradrenaline. That's nature's espresso shot. That in turn tells fat cells to burn more calories and it makes your insulin receptors more responsive. Conversely, a hot sauna makes your blood vessels relax and your body release heat shock proteins. Those can repair damage to other proteins.
Finally, you can also shorten the hours you eat during the day and prolong your fasting overnight. That can improve a whole host of healthy biomarkers. It's called intermittent fasting. And it lowers your circulating insulin, drops growth factor switches on autophagy, which is your cell's "garage cleaning" process. Altogether, these bite-sized stressors simply nudge key biomarkers of aging, things like blood glucose and C-reactive protein and HDL cholesterol, even heart rate variability, they nudge them in a younger direction without requiring a prescription or a personal trainer.
Let's not forget the trap of "emotional rigidity". As we get older, we tend to play on repeat a predictable internal soundtrack. It sounds like frustration at politics or worry about finances or nostalgia for "how things used to be". When we rehearse the same emotions daily, it strengthens those neural pathways and makes them less flexible, more rigid. Your heart also becomes less heart rate variability drops and risk of heart disease goes up. The remedy is to practice new emotions on purpose. If impatience and irritation are your default emotions, end your day by listing three ways that strangers showed kindness to you that day. If anger and anxiety are your emotional home, schedule something calming and playful where perfection is impossible. Maybe that's improv or pottery or pickleball. Just make it something you haven't tried and that elicits new emotions. Find a new emotional home for a while. Flex your feelings the way you stretch your muscles. Push the boundaries of what's comfortable.
A final comfort trap is "purpose drift". Job titles vanish, children leave the nest, and suddenly we are left asking the question, "why am I here?" Purpose isn't just philosophical, it's physiological. When we have a well-defined reason to get up every morning, our body produces more of the hormones that reduce inflammation. Finding purpose doesn't mean you have to go out and create a global foundation and leave a lasting legacy. It can be as simple as just "being there" for your grandkids or knowing that people count on you to lead Bible study. The specifics matter less than the genuine sense that your actions are rippling outward.
My client Linda was a good example of this. At 62, she left corporate America and was eager to step into her Next Act. But she quickly found herself directionless. So I just nudged her towards a weekend photography workshop that she'd been thinking about for a while. She enjoyed it so much that she immediately invested in a digital camera and she started waking up before dawn to chase mountain sunrises. When she was editing photos, it forced her to learn new software. She started posting them online and that connected her with friends on social media she hadn't seen for a while. She even started co-teaching with one of the instructors from the photography workshop she'd attended. Nine months later, she found that her resting heart rate was better, her LDL cholesterol had dropped, she was happy to get out of bed every morning, and she just kept making small, meaningful changes that landed her squarely in the sweet spot between excitement and fear.
If you're wondering how to get comfortable being uncomfortable, here's a suggestion. Imagine your day as a calm pond. Each calculated change or micro-discomfort is a pebble you're going to throw into that pond to create a few ripples. The first pebble might be as humble as ending your warm shower with a 30-second cold blast of water. You're going to gasp, your skin's going to deep in your cells, those mitochondrial "engines" are going to fire up. The next pebble you toss in might be an experiment with skipping dinner once or twice a week, allowing your body a longer overnight fast that triggers cellular housekeeping. Pebble three could be a weekly "tech date" where you and a friend explore a new app or AI platform. Have fun together, laugh at the mishaps, savor your victories, and you both get to build your neuroplasticity and social connection at the same time. Perhaps on Saturday you swap your familiar neighborhood stroll with a trail that just is steep enough to make your quads quake. Sunday evening you might attend a virtual workshop. Maybe it's a beginner Spanish class or watercolor class, anything that makes you feel deliciously inept for an hour or so. Add tiny stones day after day and soon the surface of your biological pond is going to shimmer with youthful ripples.
There's a cultural myth that says, "take it easy, you've earned if ease and comfort equals happiness. And yet we know from the science that lasting health and happiness blooms at the edges of our comfort zones when we stretch beyond our current abilities. Physically, mentally, emotionally, socially, we need to be stretched. Our bodies and minds were made to be used. Use it or lose it, right? Not too much stress and not too little stress. We are looking for that Goldilocks in between of "just right".
Comfort may feel safe, but biologically it signals retreat. That's why you're not retreating. You're a ninja who's stretching and honing the resilience that many people never get to cultivate. That's how you're going to keep extending your healthspan and wealthspan and creating your best Next Act.
Now, if this episode threw a pebble into your pond of complacency, I want you to share it with a friend who's coasting, somebody else who needs it. And if you need a coach to architect some micro-stressors into your life, hit my calendar link in the show notes and book a discovery call.
