I love tiny self-assessments like this.
Related, how much time do you spend using your peripheral vision as the primary source of information from your visual field?
. @jvisserlabs warns that a simple 10-second test can predict whether you'll die within the next decade
"If everyone wants to know within ten years whether they're going to die or not, a simple test is to see if you can stand on one leg for 10 seconds."
"The number two killer in the world behind heart disease is falling. And it's not from dying from the fall - it's that once you fall and you're older, muscle atrophy goes much faster than when you're younger."
"I always think of a leaf in the wind, just kind of floating around. If the breeze was strong enough, the leaf wouldn't come down for a long period of time. Aging is the thing where you have more control over your aging than you realize."

E182: @jvisserlabs - Why Aging is a disease, Why Bitcoin is a hedge against abundance and why you shouldn't buy a house!
Jordi Visser spent three decades on Wall Street, from a Morgan Stanley trading desk to CIO at Weiss Multi-Strategy. These days he studies AI, macro, and longevity full time. We cover why he thinks aging is optional, why Bitcoin is the only asset he'd bet on for the next decade, and why money never actually made him happy.

My four year old asked me why I was breathing weird in the car.
I was doing a sixty second session in the driveway before walking inside. Scrubs still on. Twelve hours of someone else's autonomic nervous system on my hands. Then a Slack thread about a deployment. Then this kid who just wants to know about volcanoes.
Forty four percent of the world's workforce is significantly stressed every day according to Gallup. I believe it. I'm three of those jobs.
@pausalityapp started because the person building the tool needed the tool.
Your nervous system already knows how to do this.
28 years as a nurse. Friday night after Seattle Tech Week, I sat in my driveway and ran six Pausality breathing sessions. The 4-7-8 pattern dropped my heart rate from 73 to 69 in under a minute. No medication. One breath cycle.
Your body has the same wiring. Sixty seconds and a single exhale could change how your whole evening feels.
How do you come down after work?
The subject is also the clinician. The data is also the portrait.
We built @Pausalityapp to make the nervous system visible.
Turns out the most honest imaging study I've done is on myself.
Somnistics Research Labs.
Re-embody humanity one breath at a time.
An hour from my house, some days none of my patients speak English. The nervous system doesn't speak English either. When words aren't available, you read pure physiology. 28 years of that gives you a fluency nobody is offering a course in yet.
Session 3 of 21. Box breathing. 65 bpm at the start, 54 by the end.
That's an 11 bpm drop in under a minute. No medication, no lab work. Just a deliberate exhale pattern and a watch on my wrist measuring the shift in real time.
This is what preparation looks like between cases. Train the reset before you need it.
@pausalityapp
I've used 4-7-8 breathing before more difficult airways than I can count.
For the curious:
Inhale 4 counts, hold 7, exhale 8. The long exhale is the whole point. It tells your nervous system the threat is over. One cycle and you feel the shift in your hands.
For the really curious:
That extended exhale activates the parasympathetic branch via vagal afferents. CO2 tolerance builds, chemoreceptor sensitivity recalibrates, and your heart rate variability widens in real time. The prefrontal cortex stays online instead of handing the keys to your amygdala.

Somewhere around year 15 of putting in breathing tubes, I noticed something funny.
My patient's heart rate would spike. So would mine.
28 years of that and you start building an app about it.
Case 6 of 9. It's 0900 and my heart rate reads 48 bpm.
I trained that number. Between cases I run a 60 second breathing session. Slow exhale, parasympathetic activation, vagal tone reset. By the time I pick up the laryngoscope again, my prefrontal cortex is running the show instead of my amygdala.
Think clearly when it counts.

Purposeful breathing is a bridge from conscious thought directly to the nervous system.
I'm so glad he found relief.
Curious if it works for the hiccups after I eat something unexpectedly spicy.
Simple techniques to share with family and friends.
Last year we co-sponsored the first AANA hackathon with Medtronic. Can't make it this year, but watching the mentor posts roll in on LinkedIn and it's good to see.
For anyone heading to Congress in August, here's something that works in the OR and works in a crowded expo hall:
Look around the room. Find the most comfortable person there. Be more comfortable than that.
It's called 4-7-8 breathing. Inhale for 4 seconds, hold for 7, exhale for 8. Three cycles and nobody needs to see you do it.
I have 7 peds cases in the morning and I'll use it before the first one.

1. Exploring easy ways to keep a fit and active lifestyle.
Compounds beautifully to dewreck your 40s and beyond.
2. Self-compassion.
I learned this concept during covid and could have used it to make 20's and 30's more fun.
3. Learning how your mind works from a neurosurgical persective.
Mind Magic by Dr. James Doty is a very special and useful book.
The silent killer - a lack of curiousity.
The thing that surprised me wasn't the patient's heart rate. It was mine.
Twenty-eight years of intubations and I'd never once looked.
That realization became @pausalityapp.
At some point during 28 years of intubations, I stopped watching the monitor and started noticing my own heart rate.
Turns out the person holding the laryngoscope has a nervous system too.

Quick correction: it's @pausalityapp.
The thing that surprised me wasn't the patient's heart rate. It was mine. Twenty-eight years in and I'd never once looked.
That's what we built.
Correction on my last few posts: it's @pausalityapp, not @pausality.
When you build your own product and still tag the wrong handle, that's the clinician to founder journey in real time.

After a 14-hour shift I sit in my Tesla in the driveway and do a breathing session before I walk inside.
My family doesn't need the version of me that just pushed rocuronium at 2 AM. They need the version that can listen to a four-year-old talk about dinosaurs.
Six minutes with the windows up and the watch recording everything.
Three months of consistent practice and my resting heart rate dropped seven beats per minute.
I didn't change my diet. Didn't start running. Just 60 seconds of controlled breathing between cases, most days.
I'm not making a clinical claim. I'm reading what the watch says.
