What is your biological sex assigned at birth?
Used to calibrate sex-specific screening thresholds and hormone baselines.
What is your date of birth?
We use it to calculate your exact age for screening thresholds and risk calibration. Together with your first name, it also lets us locate your report if you ever reach out to us.
What are your top 1–3 health goals right now?
Select up to 3. These prioritise which sections of your report get the most focus.
How would you rate your current health knowledge?
This calibrates how much detail and explanation the report provides.
Beginner — explain everything
Expert — keep it clinical
Are you currently under the regular care of a physician?
Step 1 of 6
Step 2 of 6
Family history.
Your family's health story is written into your biology. These questions unlock the risk factors most likely to be relevant to you specifically.
Do any of your parents or siblings have a history of heart attack, stroke, sudden cardiac death, or major coronary intervention (bypass or stents)?
Familial cardiovascular risk is graded — the earlier the onset, the stronger the genetic signal. Premature CVD (before age 60) is the strongest flag, but CVD in the 60s–70s in close relatives still meaningfully elevates risk.
Has anyone in your immediate family been diagnosed with high cholesterol or familial hypercholesterolaemia (FH)?
Any first-degree relatives with type 2 diabetes?
Any family history of Alzheimer's or dementia?
If yes, APOE genotype testing becomes a high-priority recommendation — it changes prevention intensity significantly.
Any family history of cancer? Select all that apply
Did either parent live past age 85?
Any family history of autoimmune disease? (e.g. lupus, rheumatoid arthritis, MS, thyroid disease)
Any family history of kidney disease or early kidney failure?
Step 2 of 6
Step 3 of 6
Your personal health history.
Existing diagnoses, medications, and history help us tailor recommendations — and flag any contraindications.
Have you been diagnosed with any of the following? Select all that apply
Are you currently taking any prescription medications?
Are you taking any supplements regularly? Select all that apply
Have you ever had a significant head injury or concussion?
How would you describe your current weight trend?
Have you had any major surgeries or significant hospitalisations?
Do you have a history of an eating disorder?
This modifies how the nutrition module is framed and flags bone density as a priority.
Have you ever been told you have sleep apnea, or do you snore heavily?
Untreated sleep apnea raises cardiovascular risk 2–4× and doubles dementia risk — it's one of our 8 automatic override flags.
Step 3 of 6
Step 4 of 6
Your lab results.
Enter what you have — skip what you don't. Every gap becomes part of your personalised lab priority list. Pull up your most recent results if you have them nearby.
Don't have results yet? That's completely fine — skip any fields you don't have. The assessment will generate a priority list of the specific tests you should order first.
When was your most recent full physical exam?
Standard lipid panel Optional
Enter values from your most recent bloodwork.
Enter a number or prefix with < (e.g. <70)
Blood sugar markers Optional
Enter a number or prefix with < (e.g. <5)
Advanced cardiovascular markers Optional — most impactful
ApoB and Lp(a) are the two tests most people have never had — and the two most likely to change your risk picture.
Nutrient markers Optional
Thyroid markers Optional
Blood pressure Optional
Most recent reading. Home readings are more accurate than a single clinic measurement.

Step 4 of 6
Step 5 of 6
Your lifestyle.
Six sub-domains: movement, nutrition, sleep, stress, exposures, and body composition. Answer as honestly as you can — the assessment is most useful when it sees the real picture.
Movement & Fitness
How many Zone 2 or above cardio sessions do you do per week?
Zone 2 = a pace where you can hold a full conversation comfortably (brisk walk, easy cycle, slow jog).
How many strength / resistance training sessions per week?
Approximate daily step count?
How many hours per day are you primarily sedentary (desk, car, sofa)?
Are you taking any medication that lowers your heart rate?
Beta-blockers (metoprolol, atenolol, propranolol) or calcium channel blockers (amlodipine, diltiazem, verapamil) can affect heart rate-based fitness measurements.
Nutrition
Which best describes your overall dietary pattern?
What percentage of your diet is ultra-processed food? (packaged snacks, fast food, ready meals)
How much protein do you roughly consume per day?
Target for longevity is ~1.6g per kg of bodyweight.
How many alcoholic drinks do you consume per week on average?
1 drink = 1 glass of wine (5oz), 1 beer (12oz), or 1 shot of spirits (1.5oz).
What is your typical eating window? (from first to last bite)
Sleep
How many hours of sleep do you typically get per night?
How would you rate the quality of your sleep overall?
Very poorExcellent
How long does it typically take you to fall asleep?
Is your sleep timing fairly consistent (bed and wake time within 30 minutes) most nights?
What time do you typically stop consuming caffeine?
Stress & Recovery
In the last month, how often have you felt unable to control the important things in your life?
PSS-1 (validated Perceived Stress Scale)
In the last month, how often have you felt confident about your ability to handle personal problems?
PSS-2 (reverse-scored)
In the last month, how often have you felt that things were going your way?
PSS-3 (reverse-scored)
In the last month, how often have you felt difficulties were piling up so high you couldn't overcome them?
PSS-4
Do you have a regular recovery practice? Select all that apply
Exposures & Environment
Smoking history
Have you had significant occupational or environmental exposures? Select all that apply
Body Composition
Height, weight & waist circumference Optional but recommended
Used to calculate waist-to-height ratio — a far better metabolic risk proxy than BMI.
📏 Measure around the top of your hip bones (about navel level) — not your pant size. Full guide below ↓
📏 How to measure your waist correctly — and why your pant size doesn't count ›
Your waist circumference is one of the five criteria for metabolic syndrome, so an accurate number matters. The most common mistake is using your pants / trouser size — trousers sit low on the hips and usually read several inches smaller than your true waist.
- Stand up straight, feet about hip-width apart, and breathe normally. Measure against bare skin or one thin layer — not over a sweater or belt.
- Find the top of your hip bone (the iliac crest) on each side. Run a flexible tape all the way around your middle at that level — for most people this is at about the height of the navel (belly button).
- Keep the tape horizontal (parallel to the floor) and snug against the skin without compressing it.
- Relax your abdomen — don't suck in or hold your breath. Take the reading at the end of a normal breath out.
- Record the number with its unit (e.g., "36 in" or "91 cm").
❌ Don't use your pant size. Trousers sit below the true waist, so that number runs low — often enough to change whether the metabolic-syndrome threshold is met.
Landmark follows the NCEP ATP III / NIH protocol used for the metabolic-syndrome waist criterion.
Step 5 of 6
Step 6 of 6 — Final Step
Mind, relationships & purpose.
The Harvard Study of Adult Development followed people for 85 years. The single strongest predictor of health at 80 wasn't cholesterol — it was the quality of close relationships. These questions matter as much as your bloodwork.
How satisfied are you with the depth of your closest relationships?
Harvard Study of Adult Development: relationship quality at midlife is the #1 predictor of physical health and cognitive function in later decades.
Very unsatisfiedDeeply fulfilled
How often do you feel that you lack companionship?
UCLA Loneliness Scale — Item 1 of 3. Loneliness raises all-cause mortality risk by ~26%, equivalent to smoking 15 cigarettes a day.
How often do you feel left out?
UCLA Loneliness Scale — Item 2 of 3
How often do you feel isolated from others?
UCLA Loneliness Scale — Item 3 of 3
How many people could you call in a genuine crisis — someone who would truly show up for you?
Research shows 1–2 deep connections are biologically protective. Quality over quantity.
Do you have a clear sense of why you get up in the morning?
A strong sense of purpose adds 2.4 years of life on average and reduces Alzheimer's risk by 30% (Rush Memory & Aging Project).
No — it's unclear to meYes — completely clear
Does your work feel meaningful to you?
Not at allDeeply meaningful
When something upsetting happens, how long do you typically take to return to baseline?
Slow emotional recovery is linked to elevated cortisol, reduced HRV, sleep disruption, and chronically elevated inflammation — and it is trainable.
Do you generally expect things to work out well for you in the end?
Dispositional optimism is associated with 11–15% lower all-cause mortality (NHS Cohort, 70,000+ women). The mechanism is partly behavioural and partly biological — optimists have lower inflammatory cytokines.
Rarely — I tend toward pessimismYes — strong optimist
Mood Screening (PHQ-2 & GAD-2 — Validated Instruments)
Over the last 2 weeks, how often have you felt little interest or pleasure in doing things?
Over the last 2 weeks, how often have you felt down, depressed, or hopeless?
Over the last 2 weeks, how often have you felt nervous, anxious, or on edge?
Over the last 2 weeks, how often have you been unable to stop or control worrying?
Adverse Childhood Experiences (ACE) — Optional but Important
Why we ask: ACE score (0–10) is one of our 8 automatic override flags. A score of 4 or higher is associated with significantly elevated cardiovascular, autoimmune, and metabolic risk — and changes the framing of all recommendations. These questions are completely optional. Answer only what you're comfortable sharing.
