The Health Score Calculator produces a single 0–100 score that summarizes key health and lifestyle factors — age, BMI, blood pressure, cholesterol, smoking status, activity level, diet quality, sleep, and stress — by applying modest penalties and bonuses for risk and healthy behaviors; the score gives a quick status (Excellent, Good, Fair, or At Risk) and offers targeted suggestions such as improving activity, diet, sleep, or seeing a clinician for high blood pressure, high cholesterol, or smoking cessation — use it as a general awareness tool and consult a healthcare professional for diagnosis or medical decisions.
