The Underrated Biomarker That Predicts Stroke & Dementia Risk
It’s not HRV, glucose, or inflammation. But it predicts your risk of stroke, dementia, and kidney decline decades before symptoms.
When was the last time you checked your blood pressure—without being told to?
Most people only learn their numbers when they’re already high.
But here’s what often gets missed:
Blood pressure is one of the strongest, easiest-to-monitor predictors of long-term health.
And ~50% of all U.S. adults already fall above the “normal” range.
That’s not just a cardiovascular issue. It’s a brain, kidney, and aging issue.
Let’s unpack why—plus the simple protocol I’ve followed to keep mine at 101/66 for 20+ years.
No meds. No salt restriction.

I work, think, even exercise on 5–6 hours. How big a deal is my sleep?
A member recently asked me something that captures what so many health-conscious adults wonder but don’t always say out loud:

Do I just need less sleep as I get older?
Do I just need less sleep as I get older? Do you ever find yourself thinking: “I’m 52, I wake up around 3–4 a.m., and I function. Maybe I just need le
I’ve been taking Benadryl every night for years. Is it bad?
I’ve been taking Benadryl every night for ~3 years now. It’s the only thing that knocks me out. Is it bad?”
This question appeared in my inbox recently, and variations of it come up often. The person mentioned some lingering grogginess in the morning, but otherwise assumed everything was fine.
If some version of that lives in your head, you are not the only one.
Millions of adults use over-the-counter antihistamines as a nightly sleep aid.
The reasoning makes sense: it’s available without a prescription, it’s affordable, and it does produce sleepiness.
On the surface, it looks like a small trade: a familiar allergy ingredient, a predictable sedative effect, and side effects that look like “a little groggy” or “weird dreams.”
This article is about what sits underneath that trade:
The underappreciated risks that go beyond next-day drowsiness.
Why long-term use matters for brain health and dementia risk.
How these drugs disrupt your sleep architecture—even when they help you stay asleep
How to think about your next step in a way that matches the complexity of your midlife physiology, instead of just asking, “What else can I take?”
Let’s get started.

Kidney Stone Prevention (beyond hydration & avoiding spinach)
A lot of Longevity Vault members have asked me over the years: “If I just drink more water and avoid spinach, am I safe from kidney stones?”Or: “Kidney stones run in my family—does that mean I’m stuck with them?” Short answer: those things matter. Longer answer: they only touch a small part of the problem. Most kidney stones—70-80%—are calcium oxalate. So if you’re thinking about prevention, oxalate is the main variable. That sets up the more useful question: Is “water + avoiding high-oxalate…

The Cholesterol-Handling Strategy Many Healthy Individuals Haven’t Utilized: When clean eating isn’t enough for LDL-C
For many health-conscious adults, LDL-C and ApoB remain higher than expected despite clean eating and regular exercise. One less-utilized factor is microbiome-driven cholesterol handling—the way gut bacteria and bile acids determine how much cholesterol is cleared from circulation versus recycled over time. Key topics covered in this piece: How gut microbes regulate cholesterol clearance: Longevity-supporting
The LDL-C Risk Healthy Eaters Overlook: Longevity-Supporting Microbes vs. Inflammatory Microbes for Cardiovascular & Brain Health Protection
Adults with LDL-C or ApoB above their target often already exercise, eat whole minimally processed foods, and pay reasonable attention to saturated fat. One under-addressed reason LDL-C stays elevated is that a healthy lifestyle does not automatically create a longevity-leaning gut microbiome. The gut is not only a digestion site — it is an ecosystem
