    How the Algorithm Works

    😴
    Sleep Quality
    7–9 hours optimal. Each hour under 6h adds ~1.5 years biologically.
    🏃
    Physical Activity
    150 min/week reduces mortality by 30%. 5+ days/week is optimal.
    🥗
    Diet Quality
    Mediterranean-style diet linked to 4–6 year biological age reduction.
    🧘
    Stress Level
    Chronic stress accelerates telomere shortening by up to 10 years.
