Frailty
A clinical syndrome of reduced reserve and increased vulnerability — the downstream consequence of unchecked sarcopenia and age-related decline.
Definition
Frailty describes a clinical syndrome with reduced physiological reserve across multiple organ systems, marked by weakness, exhaustion, slow walking speed, low activity and unintentional weight loss. It predicts mortality and disability independently of specific disease states. Preserving muscle mass and function through the 40s, 50s and 60s is the main preventive lever.

Sarcopenia
Age-related loss of muscle mass and function — the silent metabolic disease that undermines most other longevity efforts.
