Years You Can Add Back
10 questions. We'll score your healthspan 0–100 and show the 3 habits costing you the most years — each tied to a named expert with a citation.
No death-date prediction. Every factor traces to a named expert's position in our corpus of 3,500+ videos, with the report it came from.
How old are you?
Used to personalize your protocol — not for prediction.
Biological sex?
Affects baseline risk patterns experts cite.
Height + weight?
Used to compute BMI. Attia is famously skeptical of BMI on its own — we'll surface his nuance.
How many hours do you sleep on a typical night?
All the experts treat sleep as the single most important pillar.
How often do you exercise?
Attia: cardiorespiratory fitness is the strongest predictor of all-cause mortality.
How would you describe your diet?
Be honest — this is between you and the form.
How much alcohol do you drink?
Walker, Huberman, Attia, and Hyman all flag alcohol as a sleep-architecture wrecker.
Do you smoke or vape nicotine?
Hyman frames smoking as historically the global #1 killer — a stance shared across our experts.
Do you have any stress / heat / cold practice?
Sauna, cold plunge, breathwork, meditation — anything that hormetically stresses your system.
How would you rate your social connection?
US Surgeon General Vivek Murthy: chronic loneliness carries mortality risk comparable to smoking 15 cigarettes/day.
