As a middle-aged man, I am forced to be conscious of my heart health. And if I try to overlook the subject, I discover that both my doctor and my wife restore my focus.
A person cannot neglect the condition of his or her heart, for it is a matter of life and death. If I am careless with my eyes, my teeth, or my skin, I will pay a price, but it won't likely cost me my life. If, on the other hand, I am careless about my heart health, then all the rest will not long matter.
