What is the Health Age Predictor (HAP)? Overview & Research

Created by Reid Albright, Modified on Fri, Jun 26 at 10:13 AM by Reid Albright

The Health Age Predictor is a quick survey that helps you understand how your current habits and lifestyle may be affecting your overall health. Based on your answers, we calculate a health age, which may be higher or lower than your actual age. This number is based on science—we use evidence-backed research to estimate how your lifestyle choices impact long-term health and longevity.

If your health age is younger, it means your habits are supporting long-term wellbeing. If it’s older, it may be a sign that small changes could help you feel better and stay healthier over time. Note that the health age is not a medical diagnosis, it is just a potential indication of where you’re currently at with your health and lifestyle habits.
