The simple, practical longevity habits Bryan Johnson says matter most after spending millions trying to slow aging.

Bryan Johnson just gave what arguably could be the best advice he has ever given. The man spent millions of dollars chasing longevity, measuring his body, testing interventions, optimizing routines, and trying to reverse the aging process. So when he posted a simple list titled “Everything learned spending millions on longevity,” it landed differently, because it was almost shockingly practical and he didn’t mention questionable drugs he takes (not a fan of that).

The post opens with: “This is it. Everything learned spending millions on longevity.” He frames it as advice from “Your Immortal Unc and Auntie” to “Our Immortal nieces and nephews,” then proceeds to list forty-two simple health principles anyone can start applying.

And honestly, that might be the most powerful part.

After all the bloodwork, supplements, testing, tracking, technology, and experimentation, the best advice comes back to the basics:

• Sleep (And I’ve written about this one countless times).
• Eat real food.
• Move your body.
• Lift heavy things.
• Get sunlight.
• Protect your skin.
• Take care of your teeth.
• Spend time with friends.
• Drink water.
• Reduce stress.
• Avoid alcohol, smoking, fried foods, added sugar, late caffeine (check out my app Last Sip), screens before bed, and sitting too long.
• Build routines.
• Do less of what does not work.
• Start with baby steps.

That is the message, no miracle pill, hack, or secret biohacking protocol only available to people with millions of dollars.

It’s just daily things most people already know they should do, but often overlook because they seem too simple.

Why This Post Matters

What I like about this list is that it strips longevity down to what actually moves the needle.

There is a lot of noise in the health and wellness world. One day it is cold plunges. The next day it is red light therapy. Then it is a supplement stack, a wearable, a new diet, a fasting protocol, or some complicated morning routine that looks good online, but is almost impossible to maintain in real life.

But Bryan’s list is different because it basically says:

Start with the foundation.

• Be in bed for 8 hours.
• Keep a consistent bedtime.
• Do not eat right before bed.
• Finish coffee before noon.
• Walk after meals.
• Lift weights.
• Get your heart rate up.
• Stretch.
• Floss.
• Brush.
• Drink water.
• Get morning sunlight.
• See friends.
• Turn off notifications.
• Limit social media.
• Read a physical book before bed.
• Build a calm evening routine.

There is nothing flashy about any of that, but that’s probably the point.

The boring stuff works when you actually do it consistently.

The Best Part: “Do Less”

My favorite line might be near the end:

“Do less… most things don’t work.”

That is such a good reminder.

Health can become its own form of chaos if we’re not careful. You can track everything, optimize everything, buy every supplement, test every metric, and still miss the big picture.

The goal is not to make health complicated, but sustainable.

A simple routine you can repeat for years is better than the perfect routine you quit in two weeks.

Final Thoughts

This might be the best advice Bryan Johnson has ever given because it is not really about Bryan Johnson.

It is about the basics.

Sleep like it matters.
Eat food that came from the earth.
Move every day.
Lift heavy things.
Take care of your body before it forces you to.
Spend time with people you care about.
Get sunlight.
Avoid the obvious stuff that slowly wrecks you.
Build routines your body can count on.

That is the part I love.

You don’t need millions of dollars to start living healthier. You just need to respect the things that actually matter and do them consistently.

Start there.

It will change your life.

Reflections on Bryan Johnson’s story and the rare calm that comes when a connection simply fits.

Some stories hit close to the heart because they name something you have quietly felt but never said out loud. Bryan Johnson’s announcement today, that he has a new girlfriend, did exactly that. Bryan Johnson, 48, and Kate Tolo, 29, have a story that feels grounded and sincere, a reminder of how connection can build slowly and quietly over long stretches of shared work, trust, and honesty. It is rare to come across a relationship story told with this kind of openness and intention.

There are times in life when you meet someone and something in the exchange feels different. Not dramatic. Not loud. Just unmistakably right. Two puzzle pieces that suddenly reveal why the edges of past relationships never fully aligned. It creates a feeling of calm recognition, of presence, of seeing and being seen. You do not demand anything from it. You simply feel grateful that such a connection exists at all.

Reading Bryan’s words made me think about how people cross paths, how timing shapes everything, and how the right person can bring out parts of you that had been quiet for a long time. When he described Kate as land after years at sea, that metaphor captured something that many of us feel when someone new brings steadiness, light, and clarity into our lives. Even before anything is defined, you sense the possibility of something meaningful, something built on trust and shared effort.

His story is a reminder that deep companionship is one of the greatest human experiences. It is also a reminder that the right fit is not always fast. Often it grows slowly, through shared values, respect, and the gentle consistency of showing up for each other. The right person makes your world feel more grounded. They change how you think about the future without ever asking you to.

In Bryan Johnson’s Words

With that, here is Bryan’s full announcement in his own words…

"Guys…I have a girlfriend.

Now I know what you’re thinking…how is it possible that anyone would want to be with me? I understand where you’re coming from. I think the answer is: her puzzle piece fits mine.

In my early twenties, I read the biography of the American founding father John Adams. He and his wife Abigail had one of the great partnerships in American history; intellectually matched, emotionally intertwined, and co-architects of something bigger than themselves. I wanted what they had.

But it wasn’t within reach. Years before, I’d married in a sort of arranged Mormon marriage. Unsure how else to explain it. We were functional, but we weren’t John and Abigail. We split after thirteen years. 

At age 34, after selling Braintree Venmo, and emerging from a mismatched marriage and the repression of Mormonism, I set out to rebuild myself and find partnership.  I met a woman in LA who became my first-ever girlfriend. Coming from a sheltered background, I was blind to the obvious warnings. I was dangerously naive. That relationship unraveled and was followed by litigation. The experience was unnerving and left me wondering if I could ever trust again.

By the time I was 44, I started reconciling with the possibility of a life without partnership.

Kate Tolo and I met at my brain interface company Kernel. She’d discovered my work using neurotechnology to improve human well-being and merge human and AI. Even though she’d been dreaming of a career in fashion, she was drawn to what she foresaw as the defining question of our time: how will humans successfully co-evolve with AI. We shared the same obsession.

The puzzle piece fit was immediate, as immediate as either of us had ever experienced.

Yet we maintained our professional boundaries. When we worked on our first project together, the back and forth was effortless. She could conceptualize and feel what I couldn’t and vice versa. It helped that both Kate and I had a natural disposition towards hard work. Our joy came from creation.

Kate was luminescent. When I saw her about the office, butterflies fluttered in my stomach.  Each day she’d show up wearing some unexpected combination of colors, textures, styles and accessories. Always tasteful, playful and interesting. She didn’t chase fancy brands. Most of her clothing was from the thrift store. It wasn’t how she looked but how her mind worked: original, eccentric, entirely her own. She was art.

We both worked very hard and valued every second of the day.  One evening around 6:30 pm she dropped by my office and we talked for hours. It had been all business before.  This was the first time we stepped into each other’s personal lives. My heart strings pulled but my brain pushed back. ‘We know we can’t trust again’, my mind firmly stated.

Our after-hours meet-ups in my office became a daily ritual. The favorite part of my day. We’d reminisce about work and tiptoe a bit deeper each time into each other’s personal lives.

I’d recently started my new anti-aging project and one night Kate suggested to me that I should put the entire thing online to allow others to follow on. We worked together to put up a website and got a v1 out. We pondered what to call it, and decided on ‘Project Blueprint’.

We were oddly from entirely different worlds but somehow the same person. Yet neither of us dared take the next step. We didn’t want to imperil our work relationship and we remained deeply skeptical of each other.  The combination of Kate being raised to distrust all things and me still feeling the sting of the previous relationship left us stirring in a pot of anticipatory disaster.

Before long, whether we liked it or not, we’d become each other's favorite person. We’d spend every moment we could together. Social events and the weekends were still off-limits as our relationship was professional. We were both secretly wondering, ‘does the other person feel what I’m feeling?’

Unable to withstand any longer, after a year and a half of unspoken affection, one night I softly floated the balloon of inquiry. She confirmed it was reciprocal.

Still, with things being so new, neither of us wanted to make our relationship public. We needed time to stabilize, mature and assess whether this was short or long term. I’m a 48 year old American, raised Mormon, with three children. She’s a 30 year old Bosnian-Australian-American. It took time to bridge our worlds. In our years of knowing each other, three of them have been navigating a relationship. All while building a business and movement. There have been many times where we didn’t know if we’d make it.

In the last year, we’ve found our flow.  I trust Kate as much as my mother. She knows how to scaffold trust. She anticipates your anticipation and knows your reaction before you react. She’s meticulous in the integrity of our relationship. She’s even been pivotal in helping my father and me reconcile and navigate the contours of our relationship.

In the past few years, Blueprint and Don’t Die have become global phenomena. Kate is the unsung hero.  She and I have been stride on stride since inception. She’s proven an exceptional executor and despite her unconventional background, intuitively knows things. Her creativity keeps me forever guessing what she’ll say or come up with next. Our minds have become so intertwined that life feels naked without her.

Her story warrants being told as others will be better off emulating her practices and abilities.

What I find most impressive about Kate is her prescience and thoughtfulness. She sees forwards, backwards, and side to side. Relative to her, I feel myopic in my awareness of the world. She can see through others, as an x-ray would. She then structures all that information and can package it in simple, understandable terms. In ways that allow for everyone to win.

Kate is soft spoken, self-deprecating and understated. These attributes cloak her ferocious ambition, piercing intellect, and delightful creativity. Give her five minutes and she will reframe your world. But most people don’t know to look. They assume she’s my assistant. It’s such a loss because people are looking for what she has to offer.

My son Talmage, Kate, and I are family. Nothing makes us happier than being together. Our conversations are fast, dark, and rowdy. Family feeds the soul, and we are nourished. As my son considers possible partners, he wisely models them off of Kate.

Deep companionship is a universal human want.  And while there are eight billion of us on this planet, most struggle to achieve it, including those in relationships. It’s the most fulfilling of human experiences and also the most elusive. The joy of being seen, appreciated and loved, and offering the same to another.

I wrote dozens of different sentences trying to capture what the want and struggle for deep companionship feels like. I deleted them all as none could holistically capture the emotional architecture of it.

Then one day while exercising, I realized what it feels like: what the explorer Ernest Shackleton and his crew must have felt returning to land after being shipwrecked and surviving 497 days adrift in brutal Antarctic.

It’s a bit of a dramatic comparison, however, I suspect many of you can relate. Kate feels like land to me after being adrift and searching for 25 years.

Life sinks or sails based upon the quality of our most intimate relationships. No amount of professional success can plug the sinking hole of an acrimonious personal relationship.

At this point, Kate and I have nearly become one person. We have entire conversations with a single look, sound, gesture or image. We independently come up with the same ideas and insights, suggesting to me that maybe it’s our tandem effort generating them. Our relationship is stable, positive, and calm.

I’ve wanted this my entire life and impatiently waited 25 years for it to arrive. It’s better than anything I imagined.

Lucky me, I found my Abigail Adams."

Final Thoughts

Stories like Bryan and Kate’s remind us that the search for deep companionship is one of the most universal, most courageous undertakings in a person’s life. It asks you to stay open even when you have been hurt, patient even when timing is uncertain, and hopeful even when the path forward is not obvious.

The right connection never feels rushed. It grows in a space of honesty, trust, curiosity, and shared purpose. It deepens through small moments that add up to something significant. It brings peace instead of pressure. It makes the days feel lighter. And when it is right, you do not have to force it. You simply recognize it.

There is something powerful about being reminded that real partnership still exists and that it often shows up in unexpected ways. Bryan found his Abigail Adams. For anyone reading who feels a quiet spark with someone in their own life, this story might serve as a gentle reminder to stay open, stay present, and trust the timing of your own unfolding.

Because sometimes the person who feels like land is already walking beside you.

How heat, cooling, and detoxification shaped one of the most surprising fertility turnarounds in modern wellness.

If you use the sauna regularly and plan to have children in the near future, Bryan Johnson’s latest update should catch your attention. His recent post reveals something that many people in the longevity and health optimization space may overlook. Certain protocols can support deep health improvements, but they can also create temporary effects that matter when fertility is part of your long term plan.

Bryan shared that after reintroducing cooling during his sauna sessions, his fertility markers rose to all time highs. His total and motile sperm count now exceed that of nearly every man across all age groups, even men under 25. The numbers are impressive, but the journey to get there is what matters most for anyone using sauna as part of a detox or longevity protocol.

Here is practical knowledge for anyone who wants to combine longevity practices with future family planning.

The Key Insight

Sauna offers powerful cardiovascular and detoxification benefits, and it may support the removal of microplastics and environmental toxins. But high heat around the testes can temporarily impair sperm production and motility. Once Bryan removed cooling from his routine, his fertility markers dipped in two clear waves. When he added cooling back, they fully recovered and then exceeded his previous highs.

Sauna can heal. Sauna can stress. Cooling changes everything.

Heat, Ice, and the Biology Behind Fertility Changes

Bryan describes two distinct waves of decline that followed his weeks of sauna without ice protection.

Wave One: Immediate Decline

After two weeks without cooling, sperm motility and total motile count fell sharply. Total sperm count remained stable. This matches known biology. Mature sperm spend about two weeks in the epididymis before ejaculation. Heat damages sperm in storage first, so the drop is quick and noticeable.

Wave Two: Delayed Decline

About four weeks after reintroducing ice, another drop appeared. This reflected damage to earlier stages of sperm development. Heat can affect spermatogenesis as sperm form, mature, and develop their structure. These effects do not show up immediately. They surface weeks later as that generation of sperm completes its cycle.

Full Recovery Within Ten Weeks

Bryan’s sperm count, motility, and morphology returned to normal within a complete spermatogenesis cycle. Then they rose significantly beyond baseline.

His final numbers include:

• Total count: 600 million
• Concentration: 162 million
• Motility: 55%
• Total motile count: 330 million
• Morphology: 10% normal

These numbers place him in the top 0.4% of men worldwide.

Why the Rebound Was So Strong

Bryan suggests four potential contributors to his fertility improvement:

• Better vascular health from daily sauna
• Near complete removal of microplastics from his blood and ejaculate
• Dramatic detoxification of environmental toxins
• Consistent cooling during heat exposure

Each one has early scientific support. Combined, they may create a powerful environment for reproductive health.

Globally, male fertility has dropped by nearly 50% in the past fifty years. The sharp rise in environmental toxins, plastic exposure, and endocrine disruptors may play a significant role. Bryan’s results may offer a hopeful counterpoint. Reduce toxic load. Support vascular health. Protect the testes from heat. Allow biology to recover.

Sometimes the path toward optimal health is not linear. It requires learning and adjusting as new data emerges.

Why This Matters for Anyone Using Sauna While Trying to Conceive

Sauna is a powerful tool. It improves cardiovascular performance, enhances detoxification, and supports longevity. Heat on the testes is a known risk for temporary reductions in sperm count and motility. The data Bryan shared is consistent with clinical findings on transient hyperthermia and with research on fever related fertility changes, which show several weeks of reduced sperm quality after the body experiences elevated core temperature.

Women do not face the same fertility concerns from sauna heat because the ovaries sit deep within the pelvis and are shielded from external temperature changes. Normal sauna use does not damage eggs or reduce long term fertility. The main consideration for women is avoiding high core temperatures once pregnant, not harm to the eggs themselves.

If you are trying to conceive, want to preserve fertility, or simply want to avoid unnecessary setbacks, using cooling during sauna or steam exposure is a simple and meaningful practice.

Bryan’s Cooling Protocol

• Ice the testes during sauna
• Use a non toxic, reusable ice pack
• Wear cotton boxers and shorts
• Place the ice pack between the layers of fabric
• Keep the ice in place throughout the session

This simple habit allowed Bryan to continue receiving the benefits of heat therapy without compromising reproductive health.

Final Thoughts

Heat is not the enemy. Ice is not the hero. They are tools. What matters is how you balance them and how you understand your own physiology. Bryan’s results offer a clear message for anyone serious about health and longevity while also wanting to maintain the option of having children.

You can support detoxification, strengthen cardiovascular health, and lower your exposure to microplastics and environmental toxins while still protecting your fertility. The key is staying aware and making intentional adjustments guided by real data instead of assumptions.

Sauna and fertility can coexist. Your future family will thank you for learning how to use these tools wisely.
