As part of my ongoing 200-Year Life Project, where I'm exploring every tool, habit, and innovation that could help extend my lifespan and optimize health, I've been diving deep into wearable tech. Today, I want to share my experience with the Ultrahuman Ring that's revolutionized how I track and improve my sleep. If you're like me, chasing that elusive goal of living healthier for longer, sleep is the foundation. Poor sleep can sabotage everything from cognitive function to immune response, and at my age, I'm not taking any chances.

What is the Ultrahuman Ring?

For those unfamiliar, the Ultrahuman Ring is a compact wearable device designed to monitor your body's vital metrics 24/7. Its focuses on actionable insights without the bulk of a smartwatch. It tracks heart rate, heart rate variability (HRV), body temperature, movement, and—most crucially for this post—sleep patterns. No screens, no distractions; just slip it on your finger, sync it with the app, and let it do the work.

I first heard about it through biohacking communities and decided to give it a shot as part of my longevity experiments. After all, in the 200-Year Life Project, every data point counts toward building a blueprint for extended vitality.

How It Tracks My Sleep

The ring uses advanced sensors to break down sleep into stages: deep, REM, light, and awake periods. It doesn't just count hours; it analyzes quality. Here's what I've learned from wearing it for the past few months:

Sleep Stages Breakdown: Every morning, the app gives me a detailed report. For example, it shows how much time I spent in deep sleep (essential for physical recovery) versus REM (key for memory and mood). Before the ring, I was guessing based on how groggy I felt. Now, I have hard data.

HRV and Recovery Score: Heart rate variability is a big indicator of stress and recovery. The ring calculates a daily readiness score based on overnight HRV, sleep duration, and other factors. If my score is low, I know to dial back on workouts or caffeine.

Temperature Tracking: Subtle shifts in body temperature can signal illness or hormonal changes. The ring caught a minor fever before I even felt symptoms, allowing me to rest up and avoid derailing my routine.

It's unobtrusive— I forget it's there—which makes consistent tracking effortless.

How It's Helped Me Improve My Sleep

Data is power, but the real magic is in the improvements. Here's how the Ultrahuman Ring has tangibly boosted my sleep game:

Identifying Sleep Saboteurs:

The app flagged that my afternoon/evening coffee was spiking my heart rate into the night, disrupting deep sleep. I shifted caffeine to mornings only, and my deep sleep jumped to over 1.25  hours per night, big win for recovery.

Optimizing My Routine: Based on trends, I started winding down with a consistent bedtime ritual: dim lights, wearing Tru Dark glasses, and wind down. The ring's insights showed my sleep efficiency climbing from 75% to 85%. For longevity, efficient sleep means better cellular repair and hormone balance.

Tracking Progress Over Time: In the 200-Year Life Project, I'm all about long-term trends. The ring's weekly and monthly summaries let me see patterns—like how travel tanks my REM sleep—and adjust accordingly.

One Standout Moment: After a rough week of travel, my readiness score hit rock bottom. Instead of pushing through, I prioritized a nap and light exercise. The next day's metrics showed a rebound, and I felt sharper than ever. This kind of biofeedback is invaluable for anyone aiming to hack their biology for extended lifespan.

Sleep isn't just rest; it's a pillar of longevity. Studies show that consistent, high-quality sleep can reduce risks of chronic diseases, enhance brain health, and even influence telomere length (those protective caps on our DNA). The Ultrahuman Ring aligns perfectly with my project by providing the tools to quantify and refine this aspect of health. It's not about gimmicks—it's about evidence-based tweaks that compound over time.

If you're serious about living longer and better, I recommend checking out the Ultrahuman Ring. It's comfortable, insightful, and a game-changer for sleep optimization. Have you tried it or something similar?

It’s Officially Locked Into My Protocol

You can now find the Ultrahuman Ring listed in my completely public longevity database.

Go steal the whole protocol. Copy it line-for-line. Tweak it. Then try to beat my scores. I dare you.

Remember: I’m not a doctor—just a determined 70-year-old who refuses to age normally. Nothing here is medical advice. Always run big changes by your physician. Let’s Build the Future of Longevity Together.

Here’s to sleeping like we’re 30 and waking up ready to conquer the next century.

I love coffee and have been drinking three to four cups a day for years. I never knew about the problems with coffee until recently and want to share that information with you.

I never knew that my coffee was slowly poisoning me.

First problem: Plastic Pods.

If you’re still using those one-time-use pods, stop today. You’re shooting 185–195 °F water through plastic. That leaches microplastics and nano-plastics straight into your brew. We already can’t escape microplastics in 2025, but we sure as hell don’t need to mainline them at breakfast. Pods also sit in warehouses for 6–18 months → perfect mold factory. Double whammy.

Here is a rundown of my dead simple morning ritual that I knock out literally within minutes of opening my eyes.

Step 1: I kick things off with 2 tbsp raw apple cider vinegar (with the mother) mixed into chamomile tea that I sweeten with a packet of stevia, hit it with two shakes of cinnamon and a few grinds of fresh black pepper. This combo loads me with prebiotics for the gut, blood-sugar control, polyphenols that crush inflammation, memory-boosting compounds, fat-cell blockers, and piperine that makes everything absorb better — all while tasting way less nasty than straight apple cider vinegar.

At 70 years old, I've decided to set an audacious goal: I intend to be the first human to live to 200 years old. This isn't just wishful thinking—it's the foundation of my new venture, the 200 Year Life Project: The Ultimate Longevity Journey.

Inspired by pioneers like Bryan Johnson and his “Don't Die” philosophy, I'm documenting every step of this radical experiment in health, biohacking, and extreme longevity and I'm inviting you to join me.

Why Now? Why Me? For decades, I pushed my body to the limit. I smoked three packs a day from 1969 until I quit in 1989. Heavy drinking was part of my routine starting around the same time, though I've since cut it out entirely. At my heaviest, I tipped the scales at over 350 pounds and now I'm holding steady at around 184 pounds. Sleep? I used to average just five hours a night, leaving me foggy and drained. Something shifted when I dove into the latest advancements in AI and longevity science.

Predictions suggest we're on the cusp of massive leaps in human lifespan: from today's average of about 78 years to 100, then 120, and beyond. I don't want to miss out. My aim is to arrive there in sound mind and body—stronger at 200 than I am today.

Watching Bryan Johnson's documentary “Don't Die” was a turning point. His relentless pursuit of reversing aging lit a fire under me. If he's pushing boundaries with rigorous protocols, why can't a 70-year-old Boomer like me do the same?

My Starting Point: Radical Changes for Radical Results.
