Testing / May 8, 2026
Do I need a coronary calcium scan?
A coronary artery calcium scan can clarify risk when the statin decision is uncertain. It is not a universal screening trophy, and it does not see soft plaque well.
Nutrition / May 8, 2026
How much protein do women need after 40?
Protein needs are not magic after 40, but the stakes change. Preserving muscle becomes more important, and resistance training plus adequate protein is the center of the plan.
Labs / May 8, 2026
Is ApoB better than LDL?
LDL-C tells you how much cholesterol is carried inside LDL particles. ApoB estimates the number of atherogenic particles. When they disagree, ApoB often better captures risk.
Supplements / May 8, 2026
Should I take creatine?
Creatine is not an anti-aging miracle. It is one of the better-supported supplements for strength, power, and training capacity, which are relevant to healthspan.
Labs / May 8, 2026
What labs should I ask my doctor for?
The best lab request is not a giant menu. It is a short list tied to risk, symptoms, medications, and what you would do differently after results come back.
Supplements / May 7, 2026
Does magnesium help sleep?
Magnesium may help some people sleep, especially if intake is low or constipation/muscle tension is part of the picture. It is not a universal insomnia treatment.
Exercise / May 7, 2026
Does pickleball count as longevity exercise?
Pickleball counts if it raises your weekly activity, challenges coordination, and keeps you consistent. It does not fully replace strength training or dedicated aerobic conditioning.
Testing / May 7, 2026
Is biological age testing accurate?
Biological-age tests are interesting research tools. They are not yet clinical command centers for individual care decisions.
Testing / May 7, 2026
Is CGM useful if I don't have diabetes?
A CGM can teach some people how their glucose responds to meals, sleep, alcohol, and stress. That does not mean every healthy person needs one.
Labs / May 7, 2026
The Labs I Actually Care About
The useful lab panel is not the longest one. It is the one that changes decisions: cardiometabolic risk, inflammation in context, liver/kidney safety, nutrient deficiencies when plausible, and follow-up markers after an intervention.
Supplements / May 7, 2026
What supplements are actually worth taking?
Most supplement stacks are longer than the evidence. The best case for supplements is targeted replacement, training support, or a specific symptom—not a shopping cart of longevity vibes.
Exercise / May 7, 2026
Zone 2, VO2 Max, Strength, and Balance: The Exercise Stack
The exercise stack is not one thing. Zone 2 builds the metabolic base, VO2 max work protects the ceiling, strength preserves independence, and balance keeps the whole system usable.

Sleep and Longevity: A Doctor's 4 Sleep Fixes (That Actually Work on Your Nervous System)
Whether you sleep okay or you're chasing something better — this guide is about what the research actually says drives sleep quality, not just the basics you've already heard. Sleep is the highest-leverage longevity intervention we have, and most people are leaving significant biology on the table without knowing it.

GLP-1 Drugs Beyond Weight Loss: The Longevity Evidence
Something unexpected happened when researchers started tracking what else Ozempic was doing. Beyond blood sugar, beyond weight — heart attacks down 20%, kidney disease progression cut by 24%, the first medication ever approved for sleep apnea, alcohol cravings quietly disappearing. This is the honest clinical picture of what GLP-1 drugs actually do, what failed, what's coming, and who should genuinely consider them.

Is rapamycin safe for healthy adults?
Rapamycin has extended lifespan in every major mammalian study. The human evidence is early, genuinely surprising in some ways, and widely misrepresented. Here is a complete clinical guide — the mechanism, the actual trial data (including what didn't work), dosing protocols physicians use, what to monitor, who's a candidate, and where the real uncertainties are.
