10.1 Physical and Cognitive Changes

Middle adulthood brings a mix of physical and cognitive changes. Vision and hearing may decline, metabolism slows, and hormonal shifts occur. However, problem-solving skills often improve, and accumulated knowledge increases.

Lifestyle choices greatly impact health during this stage. Regular exercise, a balanced diet, and stress management are crucial. Staying mentally active and socially engaged can help maintain cognitive function and overall well-being.
