Older adults are more vulnerable to illness.

Musculoskeletal Changes

Bone density decreases.
Joint mobility reduces.
Osteoarthritis is more likely to develop.
Muscle function weakens.
Type II muscle fibers decline.

Reduced Stamina and Cardiovascular Respiratory Endurance

Heart, blood vessels, and lungs function decline.
