Every part of the body begins aging at a different time. The brain starts losing neurons from age 20. Muscles decline from 30. Bones deteriorate from 35. Heart risk rises at 40-45. Kidneys decline from 50. The liver, remarkably, holds until 70.
Aging is inevitable — but the rate is not fixed.
Key practices for slowing decline:
Proper diet. Consistent exercise. Mental engagement. Stress management. Adequate sleep.
