Final answer:
Physical activity is beneficial to us physiologically, resulting in an increase in cardiovascular and other diseases.
Step-by-step explanation:
The reading by O'Keefe et al. provides evidence that physical activity is indeed very beneficial to us physiologically, leading to an increase in cardiovascular and other diseases.
Regular physical exercise has been shown to reduce risk factors for cardiovascular disease, such as hypertension and high cholesterol, while increasing factors like insulin sensitivity and exercise tolerance.
Increased physical activity has also been found to have positive effects on overall health, including improvements in cardiovascular and muscular fitness, bone density and strength, cognitive function, and weight loss and maintenance.
