Am I Normal?
Pick a metric. Submit your number. See exactly where you sit in the global distribution — filterable by age and sex.
Resting Heart Rate
Measure first thing in the morning, before standing up. Lower is generally better in the 40–70 bpm range.
Hours Slept Last Night
Time you were actually asleep, not in bed. Whoop/Oura totals work.
Morning Fasting Glucose
First reading of the morning, water only since waking. CGM-friendly.
Steps Yesterday
From your phone or watch. Yesterday's total, not a typical week.
Weekly Zone 2 Minutes
Total time at conversational pace (Zone 2 HR) over the last 7 days.
VO2 Max
From a treadmill test, watch estimate, or our VO2 Max Estimator.
ApoB
Apolipoprotein B from a lipid panel — the headcount of artery-clogging particles. Lower is better.
Fasting Insulin
Fasting insulin from a morning blood draw (8+ hours fasted). Rises years before glucose does.
Grip Strength
Best hand-dynamometer reading (either hand, max effort). Filter by age and sex for a fair comparison.
HRV (RMSSD)
Nightly RMSSD from Oura, WHOOP, Apple Watch, or Garmin. Falls with age — filter by age band.
Systolic Blood Pressure
The top number, measured seated and rested. Filter by age and sex for a fair comparison.
Body Fat
From a DEXA, calipers, or our Navy-method calculator. Healthy ranges differ by sex — filter below.
Waist-to-Height Ratio
Waist circumference divided by height (same units). The simplest predictor of metabolic risk.
HbA1c
Your 3-month average blood sugar from a lab test. Filter by age and sex below.
PhenoAge Gap (body age − calendar age)
Your phenotypic age minus your calendar age — negative means your body is younger. Get it from the Phenotypic Age Calculator.
What does "Am I Normal?" mean for these health metrics?+
For each metric (resting heart rate, HRV, blood pressure, sleep, glucose, HbA1c, fasting insulin, ApoB, body fat, waist-to-height, grip strength, steps, Zone 2 minutes, VO2 max), you submit your value and see two things: the published clinical reference range (AHA, ADA, ACSM, ESC/EAS), and the community distribution — percentile, mean, median — of readers who submitted theirs. The community comparison is anonymous and filterable by age band and sex.
Is the community distribution clinically meaningful?+
No — it's a peer comparison, not a clinical reference. Use it as a gut-check on where you sit relative to other health-focused readers. The clinical interpretation per metric is on each sub-page, sourced from AHA / ADA / ACSM / NIH.
Why filter by age and sex?+
Most of these metrics shift meaningfully with both. A VO2 max of 38 is average for a 45-year-old male and above-average for a 65-year-old female. A resting HR of 70 is borderline-high for a fit 25-year-old and normal for a sedentary 70-year-old. Age- and sex-filtered comparison is the only fair one.
Will my submission be visible to anyone?+
No. Only the aggregate distribution is exposed — the raw rows are RLS-locked and only the counted/percentile aggregates are returned by the API. Submissions carry a device hash (not an identity).
Which metric is the most important for longevity?+
VO2 max — by a wide margin. Mandsager 2018 (122k patients, Cleveland Clinic) found cardiorespiratory fitness was a stronger mortality predictor than smoking, hypertension, or diabetes. Resting heart rate and weekly Zone 2 minutes are downstream of the same trait.
Why a distribution beats a single 'normal' number
Reference ranges printed on a lab slip or a fitness watch are usually population-wide and ignore age, sex, and training status. A resting heart rate of 62 looks great in the abstract, average for a fit 35-year-old, and slightly high for an elite endurance athlete. The same with VO2 max, fasting glucose, daily steps, and weekly Zone 2 minutes — the right answer is always a distribution, not a number.
The polls in this section accumulate readers' real numbers (anonymously) and show you exactly where you fall — percentile, median, and mean — filterable by age band and sex. It's a community comparison, not a clinical reference range, but it's a much better gut-check than the textbook value.
