Calculation steps

  1. 1Body age = actual age 35 + lifestyle total +4 = 39
  2. 2Smoking: Quit → +1y
  3. 3Weight (BMI): Overweight 24-28 → +2y
  4. 4Alcohol: Occasional → +1y
This is an entertainment-grade estimate based on epidemiological risk-factor weights, NOT a medical diagnosis. Real "biological age" research uses biomarkers (telomere length, DNA methylation clocks like Horvath's, VO2max, grip strength). The good news: the biggest levers — quitting smoking, regular exercise, sleep, weight — are all actionable, and studies show lifestyle changes measurably improve biomarker age within months.
