Final answer:
Chronological age may differ from biological and psychological age due to factors like lifestyle choices and genetics. Physical activity is essential for promoting healthy aging by reducing mortality rates. Lifestyle habits play a significant role in determining one's biological and psychological age.
Explanation:
Chronological age is the number of years since someone was born, but there are other dimensions of aging such as biological aging and psychological aging. Factors like genetics, lifestyle choices, and environment can affect discrepancies between chronological age and biological or psychological age.
For example, someone who is 30 chronologically may have engaged in unhealthy habits that accelerated their biological aging, making them appear older physically. On the other hand, positive lifestyle choices like regular exercise and a healthy diet can help individuals maintain a youthful biological and psychological age.
Research has shown that physical activity plays a crucial role in longevity, with individuals engaging in moderate to high levels of activity exhibiting lower mortality rates compared to inactive individuals, emphasizing the importance of exercise in promoting healthy aging.
