A heart attack happens when one or more aorta or coronary arteries get blocked. With the passage of time, the coronary artery becomes narrow that is because of the deposition of various substances such as fat, cholesterol and other reserves.

Answer:
highly active individuals who sweat heavily
Explanation:
Dietary Reference Intake (DRI) for sodium is stated at 1,500 mg daily for sedentary individuals, men and women under the age of 50, and is adequate for normal functioning of the body, as too much intake for these categories of people might be unhealthy.
However, highly active individuals who sweat heavily, such as athletes, would need to consume a higher amount above the recommended 1,500 mg for others.Sodium is required for maintaining fluid balance as muscles and neurons need to be activated by Sodium, which is an electrolyte. Highly active people tend to lose more sodium as they sweat profusely, hence the need for a higher intake of sodium to avoid weakening of the muscles and cramps.
