• Similar to predictable stages like puberty and menopause

• Suggests aging is inevitable and biologically scheduled

🔹🧪 Biologic Mechanisms Involved

• Cells lose ability to divide and regenerate over time

• Immune system weakens due to genetic programming

• Hormonal secretion patterns gradually decline

• Organ systems age in a predictable sequence

🔹📘 Examples Seen in Older Adults
