The 5-Step Method That Keeps Relationships From Falling Apart
The couples who stayed happiest in the world's longest study of human life weren't the ones who avoided fights. They were the ones who fought differently.
After 85 years of data, the Harvard Study of Adult Development found that what separates thriving relationships from struggling ones isn't the absence of conflict; it's the ability to slow down your automatic reaction during conflict.
Researchers tracked more than 2,500 participants across three generations and noticed a consistent pattern: the people who maintained the strongest relationships weren't calmer, smarter, or more patient by nature. They were just more aware of their own emotional patterns, and they'd learned to interrupt the autopilot.
The scientists distilled these behaviors into a five-step framework called WISER, built on the study's longitudinal data and decades of research from psychologists.
Here's the process and how you can apply it to your relationships.
Watch: pause and notice what's happening in your body. Heart pounding? Jaw clenching? You can't fix what you can't see.
Interpret: ask why you're reacting this strongly. What's actually at stake?
Select: choose a response based on the outcome you want, not the emotion you feel.
Engage: act on that choice, and consider whether now is even the right moment.
Reflect: afterward, review what worked and what didn't.
The logic checks out beyond this study. Research from the Gottman Institute shows that couples who de-escalate conflict maintain a ratio of roughly 5 positive interactions for every negative one, and those relationships last.
You don't need to master all five steps tomorrow. Start with Watch. The next time you feel that surge — the urge to fire back, to shut down, to walk away — just notice it.
Name one thing happening in your body. That pause alone changes the trajectory. Think of it as progressive overload for how you handle the people who matter most.

The Drink That Keeps Showing Up in Heart Health Research
You could spend a fortune on supplements you can't pronounce or overhaul your entire diet by Sunday. Or you could boil water.
That's a simplification, but not by much.
When researchers want to know which everyday habits improve cardiovascular health, green tea keeps landing on the list of simple, practical, and effective behaviors. And the latest evidence makes a strong case for why.
Scientists analyzed 55 randomized controlled trials of people who drank green tea for 2 to 48 weeks. Compared to a placebo, adding green tea to your life nudges your cardiovascular health in the right direction by improving total cholesterol, LDL cholesterol, fasting blood sugar, HbA1c, and your blood pressure.
None of those improvements were dramatic on their own, and that's actually the point. The researchers weren't looking for a miracle. They were asking a better question: Can a simple, repeatable behavior meaningfully influence heart health over time? Across 55 trials, the answer was consistent.
The scientists believe green tea may reduce cholesterol absorption in the gut, improve how the liver processes fats, help muscle and liver cells respond more effectively to insulin, and reduce low-grade metabolic stress that accumulates over time.
Think of it less like flipping a switch and more like reducing friction. When systems move more easily, numbers tend to drift in healthier directions.
If you want a daily ritual that helps offset the inevitable stress of life, tea is one of the easiest wins we've found.

The Mental Health Case for Picking Up Weights
When your mood tanks, the last thing you might want to hear is "just exercise." It feels dismissive, like telling someone who's drowning to swim harder. But what if the research actually backed it up and showed which type of exercise works best?
A massive review of 73 studies found that exercise reduces depressive symptoms with therapy-like effectiveness.
Scientists compared exercise against no treatment, psychological therapy, and antidepressant medication across decades of randomized controlled trials.
Exercise produced a moderate reduction in depressive symptoms compared to doing nothing. When stacked against therapy, the benefits looked similar (and that comparison had the strongest evidence). The medication comparison showed promise, too, though researchers had less certainty there.
If you’re interested in writing your own mental health Rx, plans that combine resistance training and aerobic exercise appeared more effective than cardio alone. And the sweet spot wasn't crushing yourself. Moderate intensity showed the best outcomes.
Exercise increases blood flow to the brain, triggers the release of endorphins, reduces inflammation, and improves sleep. But there's also the psychological piece: accomplishing something physical when everything feels heavy can shift how you see yourself.
One important note from the researchers and independent experts: this is not about replacing professional help. For clinical depression, exercise works best alongside therapy and medication, not instead of them.
If low mood has been following you around, consider adding two or three strength sessions per week at an intensity that feels manageable, not punishing. You don't need to love it. You just need to do it enough times for the benefits to build.

The Two Things I Know About Happiness
It was already later than when I normally go to sleep. But my wife had been waiting for me to finish my nightly routine. And by nightly routine, I mean writing the APC newsletter.
I sat down next to her on the couch. And then I heard the words I’ve heard many times before:
"Can I ask you something?"
“You can ask me anything.”
“I’m not sure you’ll love this, though.”
I knew by the tone that this wasn’t an attack as much as an observation.
"The other night, when my friends were over, and they asked how you are, you kept telling them you were so great — were you being real? I know work has been crazy. And your knees have been killing you."
She wasn't doubting me. She was checking. Because she knows the version of me that performs fine when fine isn't accurate. But she also knows the former me who felt the need to say everything was fine. And she's earned the right to ask.
"But I am happy," I said.
She studied my face. Then nodded. The good nod. Not because she believed me automatically, but because after seventeen years, she can tell when I mean it. When it’s not only true, but genuine.
And I did mean it. But here's what made that moment stay with me to the point I had to write about: five years ago, I couldn't have said those words and been telling the truth. Not because life was worse then.
But I was operating under a belief that most of us carry without examining it — that happiness is what's left over when you fix everything that's broken.
It's the DNA of optimization that has taken over the wellness space in a way that started with good intentions but is now bordering on obsession and misguided effort.
Optimization is built around fixing. Identify the problem, solve the problem, feel better. And in health and fitness, where I've spent my career, that framework can work beautifully. Follow the program. Adjust the variables. Stay consistent. See amazing results.
But not every aspect of life responds to a periodized plan. Or, more appropriately, not every aspect of life is broken and needs to be fixed.
What if happiness isn't the absence of struggle but the acceptance of how much good is already here, even in the face of imperfection?
Acceptance and Appreciation
I don't have life figured out.
That sentence alone would've been impossible for me to write ten years ago. Back then, I was certain that effort and competence would eventually produce a life that felt settled. That if I worked hard enough, trained smart enough, loved fiercely enough, I'd reach the place where the problems resolved and the noise quieted down.
That place doesn't exist. And chasing it is its own kind of exhaustion.
I know what I prioritize (people and experiences), and I know that two principles — acceptance and appreciation — have helped me balance the beautiful mess that is life and feel happier.
I had to accept that my father got brain cancer and was gone far too soon. He was 68. He should've had twenty more years of football games and bad jokes and watching his grandkids grow into people he'd be proud of. I don't get to change that. No amount of anger or bargaining or replay will bring him back to the seat next to mine, to see my two boys become men, or to meet my daughter.
But I've learned to appreciate the time I have and the time he had. Not in some bumper-sticker way. In the way that shows up when I'm holding my daughter, and I feel, in my chest, how temporary this weight in my arms actually is. My dad taught me that. Not with a speech. With the way he lived his last three years, refusing to let a death sentence dictate the quality of his days.
I have to accept that my schedule will rarely, if ever, go the way I want. Three kids. A business that never fully sleeps. A body that requires maintenance, no matter how much I care for it. The calendar I imagine on Sunday night and the one I actually live bear almost no resemblance to each other.
But I get to appreciate that every week, buried somewhere between the chaos and the compromise, there are moments I would've missed entirely if I were still obsessing over the plan.
A Tuesday afternoon where chaos is all around, but I decide to let it burn for a few more minutes and shoot baskets with my oldest because he had a hard day. A 4 pm Thursday speed date with my wife, because we have 2 hours where the kids are accounted for and both of us are free. A conversation with Arnold that starts about a newsletter and ends somewhere about the mysteries of life.
These aren't consolation prizes. They're the actual thing. I just had to stop squinting past them to see what wasn't there.
Today, I accept that I'll get things wrong. I accept that I will screw up publicly, privately, and in ways I won't even notice until it's too late. And I accept that no matter how carefully I think through a position, someone will think I'm an idiot. Or worse, that I don't care.
But I appreciate that I can set standards for myself and measure my life against those, not the scorecards that strangers or algorithms assign. The opinions that matter fit around a dinner table. Everything else is weather.
The Part Nobody Mentions
When most people talk to me or meet me, they frequently tell me that they couldn’t read me. At least initially. When they hear I'm genuinely happy, but also hear me openly talk about my struggles, the contrast doesn’t seem to fit.
But the missing piece is the balance between acceptance and appreciation.
My body — despite this being my area of expertise — has aches and limitations I haven't experienced in more than twenty years. Some days my knees cooperate. Some days they remind me that I'm not the guy who deadlifted without thinking twice anymore. I've spent decades helping people solve these problems, and the irony of not being able to solve my own is not lost on me, no matter what I throw at them. I accept it.
My ambition is sometimes relentless to the point that I don't slow down enough to enjoy what I've already built. I can see the next thing so clearly that I forget to look at what's right in front of me. My wife has pointed this out more than once. She's right every time. I accept it.
And every single week, I question whether I'm a good enough father to my three kids and a good enough husband to my wife.
That probably sounds heavy. But here's what I've come to understand, and it's the thing I wish someone had told me at thirty:
That's not a sign that something is wrong. That's the human condition working exactly as designed.
Happiness and fulfillment don't require perfection. They don't even require most things going your way. What they require is a kind of emotional flexibility that I didn't have language for until recently.
It's two moves, practiced over and over.
Accept the things you don't like and can't control. Not passively. Not with resignation. With clarity. Name them. Stop fighting the wall that isn't going to move. Stop spending emotional energy on the argument you can't win against reality.
And then — appreciate everything else. Actively. Deliberately. Not because life owes you a silver lining, but because joy is a choice that compounds. The more you practice noticing it, the more there is to notice.
Those two things don't cancel each other out. That's what I got wrong for years. I thought accepting hard truths meant surrendering the right to feel good. And I thought feeling good required that the hard truths resolve themselves.
Neither is true.
You can grieve your father and feel overwhelming gratitude for every moment you had. You can be frustrated by your body and still show up at the gym because moving is the rent you pay for the life you want. You can question whether you're enough and still give everything you have, knowing that "enough" was never a fixed target anyway.
The flexibility is the whole thing. Not the absence of tension. The willingness to hold both sides of it without letting either one win.
On Your Terms
I used to think my forties would be the decade where things clicked into place. Where the work of my twenties and thirties finally produced a life that felt finished.
Instead, it's the decade where I stopped needing things to click.
I realized that the unfinished quality of life isn't a flaw in the design. It is the design. The gaps, the doubts, the weeks where nothing works the way you planned — that's not the stuff that gets in the way of a good life. That's the texture of one.
Once you stop demanding that joy arrive on your terms, it gets a lot easier to recognize when it's already in the room.
My wife asked me a fair question that night. She's watched me push through pain and call it fine. She's watched me optimize my way around problems that couldn't be optimized. She knows what it looks like when I'm performing happiness versus feeling it.
What she saw that night was the real thing. Not because the knees don't hurt. Not because work isn't relentless. But because I've stopped waiting for those things to resolve before I let myself feel what's already good.
The good life doesn't ask you to have it all figured out. It just asks you to stay flexible enough to hold what you've got — the weight and the wonder of it — without dropping either one. -AB

Take any of these tips from today’s email and put them into action:
1. Harvard's 85-Year Study Found a 5-Step Framework That Predicts Which Relationships Last
The Harvard Study of Adult Development tracked more than 2,500 participants across three generations and found that relationship longevity depends not on avoiding conflict but on interrupting automatic emotional reactions during it — a skill researchers codified into the five-step WISER framework (Watch, Interpret, Select, Engage, Reflect). Supporting data from the Gottman Institute confirms that couples who de-escalate conflict and maintain a 5-to-1 ratio of positive to negative interactions stay together at significantly higher rates. Start with step one: the next time your heart rate spikes in an argument, name one thing happening in your body before you respond; that single pause changes the trajectory.
2. Green Tea Improved Cholesterol, Blood Sugar, and Blood Pressure Across 55 Clinical Trials
A meta-analysis of 55 randomized controlled trials found that green tea consumption over 2 to 48 weeks improved total cholesterol, LDL cholesterol, fasting blood sugar, HbA1c, and blood pressure compared to placebo, with researchers identifying reduced cholesterol absorption in the gut, improved hepatic fat processing, and enhanced insulin sensitivity as likely mechanisms. The effects were individually modest but consistently directional across all trials, suggesting that the compounding benefit of a simple daily habit outperforms the dramatic claims of expensive interventions. If you're going to drink it, quality matters: look for products that preserve catechin and antioxidant content rather than destroying it in processing.
3. 73 Studies Show Resistance Training Helps Reduce Depression Symptoms
A systematic review of randomized controlled trials found that exercise reduces depressive symptoms with therapy-equivalent effectiveness, with resistance training and combined resistance-aerobic programs producing stronger outcomes than cardio alone — particularly at moderate intensity rather than high intensity. The mechanisms include increased cerebral blood flow, endorphin release, reduced systemic inflammation, and improved sleep architecture, as well as the psychological benefit of physical accomplishment during depressive episodes. Two to three strength sessions per week at manageable intensity is the evidence-based starting point. You don't need to crush yourself; you just need to be consistent enough for the benefits to compound.
4. Why the Optimization Mindset Could Be Interfering With Your Happiness
Adam Bornstein argues that the optimization mindset dominating wellness culture — identify the problem, fix the problem, feel better — fails when applied to emotional life, because happiness isn't what's left when everything is fixed but what you notice while things are still imperfect. His framework reduces to two daily practices: acceptance (naming what you can't control and stopping the fight against immovable reality) and appreciation (actively noticing existing good rather than waiting for conditions to improve). The flexibility to hold struggle and gratitude simultaneously, without needing one to resolve before the other arrives, is the skill — and like training, it compounds with practice.
