Hi friends,
Here's the thing about building Phoenix.
It's actually stressful as hell.
I wake up every night after 4-5 hours. Then my sleep is completely fragmented for the rest of the night. My Oura data looks like a war zone—constant wake-ups, HRV tanking, recovery scores in the gutter.

Believe it or not, building Phoenix is one of the most stressful things I've ever done. I value the trust you've all placed in me, and that drives me to deliver as much value as I can, as fast as I can.

But this constant stress? It's killing my sleep.
And for APOE4 carriers like us, that's dangerous.
Why Sleep and Stress Matter More for APOE4 Carriers
One night of bad sleep increases amyloid-beta accumulation in your hippocampus—the exact region that gets hammered first in Alzheimer's.
The mechanism? Your glymphatic system.
During deep sleep, your brain shrinks slightly. Cerebrospinal fluid floods in and washes out metabolic waste—including amyloid-beta and tau proteins. It's like a nightly power-wash for your brain.
But here's where APOE4 makes everything worse.
Sleep deprivation in APOE4 carriers creates a vicious feed-forward loop. Poor sleep reduces aquaporin-4 (the protein that drives glymphatic clearance), which means more amyloid builds up. More amyloid disrupts sleep even further. Rinse and repeat.
The research is brutal. APOE4 carriers under chronic stress show:
Higher cortisol levels than APOE3 carriers
Worse memory performance
Accelerated hippocampal atrophy
Increased tau phosphorylation
Stress isn't just unpleasant for us. It's neurotoxic.
Enter Zenowell: Non-Invasive Vagus Nerve Stimulation
I've been researching solutions for months. And I finally found something worth testing.
Zenowell uses transcutaneous auricular vagus nerve stimulation (taVNS)—electrical pulses delivered through your ear to activate your parasympathetic nervous system. The "rest and digest" mode. The anti-stress system.
Clinical data from real users:
25% improvement in sleep quality within 2-4 weeks
12% better HRV (heart rate variability—a key marker of nervous system health)
45% stress relief
28% reduction in inflammation
29% improvement in gut motility
The device targets the auricular branch of the vagus nerve—the only branch accessible on your body's surface. Unlike neck devices, Zenowell hits 100% of the vagus-innervated region in your ear.
Three modes: Sleep, Relax, Meditation. No app required. Works straight out of the box.
Phoenix Members Get 41% Off + Risk-Free Trial
Here's the deal we negotiated:
Regular price: $499
Phoenix study price: $294.48
Savings: $204.52 (41% discount)
Money-back guarantee: 30 days, no questions asked
Try it for a month. If it doesn't help your sleep, stress, or recovery—send it back for a full refund.
We Remain Independent. Always.
Phoenix doesn't take affiliate fees or sponsorship money. Period.
When partners offer us affiliate commissions, we ask them to pass those savings directly to you as bigger discounts. That's how we got to 41% off.
Our only incentive is finding what actually works for APOE4 carriers.
What the Study Involves
This is a 4-week commitment:
Daily 30-second check-ins on the Phoenix app
Use Zenowell as directed (20 minutes/day recommended)
Track your sleep and HRV with any wearable you already have (optional but encouraged)
Complete pre/post questionnaires
That's it. Simple, sustainable, and designed to fit into your life.
Timeline
November 25: Live webinar with the Zenowell team—ask anything
Enrollment closes: December 4th
Study starts: Once you receive your device
The Science You Can Review
We've compiled the key studies on vagus nerve stimulation, sleep, and Alzheimer's risk in a Google Drive folder here.
This Study is Reserved for Phoenix Members
If you're not a member yet, you can join while we still have our founding member offer: $499 for lifetime access.
We're switching to $499/year soon as we deploy our AI tools (which comes with recurring costs per active member for us).
Once we flip the switch, the lifetime offer is gone forever.
Why This Matters Right Now
Building the future you want—Alzheimer's-free, cognitively sharp at 80, able to recognize your grandchildren—requires managing your biology today.
Sleep and stress are two of the biggest modifiable risk factors we have.
You can't control your genes. But you can control how you respond to stress and how well you sleep.
Zenowell gives us a new tool to do both.
I'm testing it myself starting next week. If you want to join the study, reply to this email and I'll send you the enrollment form.
Let's beat the odds together.

PS: Our first medtech study was a home run
Last month, 53 members enrolled in our Neuronic study (red light therapy). Early results look strong. This proved something: when we move together, companies pay attention. We're evaluating more partnerships now—photobiomodulation, neurofeedback, vagus nerve stimulation, tDCS. Got a device you want us to test? Email me.
If the science is solid and enough members are interested, I'll make it happen. Individually, we're ignored. Collectively, we have leverage.
P.P.S.: Have questions before the webinar? Reply to this email. I read every response.
Most Newsletters? One-way street.
How boring…
This is the Phoenix Community after all—so let's make it a two-way street.
Got a question? Feedback? Just want to say hi?

I read every single one.
