These days, drug companies and health professionals alike are focusing their attention on cholesterol in the blood. The more cholesterol we have in our blood, the higher the risk that we shall die of a heart attack. The issue is pertinent since heart disease kills more North Americans every year than any other single cause. At least three factors—smoking, drinking, and exercise—can each influence levels of cholesterol in the blood.

Summary
The more cholesterol in our blood, the higher the risk of death from a heart attack. This is important, because heart disease kills more North Americans every year than any other single cause. Smoking, drinking, and exercise, including potentially other factors, can influence cholesterol levels in blood.

Very Strongly Supported Conclusions
We can reduce our chances of dying from heart attack by changing smoking, drinking, and exercise habits.

A
If a person has low blood cholesterol, then that person’s risk of fatal heart disease is low.
We know the lower the blood cholesterol, the lower the risk of fatal heart disease. But this doesn’t reveal anything about the absolute risk level. We don’t know that “low” blood cholesterol implies “low” risk. The risk could still be high, just not as high as it would be if the blood cholesterol were higher.
B
Smoking in moderation can entail as great a risk of fatal heart disease as does heavy smoking.
The stimulus doesn’t compare the impact of moderate smoking to heaving smoking.
C
A high-cholesterol diet is the principal cause of death in North America.
We know heart disease kills more North Americans than any other single cause. But we don’t know that this heart disease is primarily caused by a high-cholesterol diet.
D
The only way that smoking increases one’s risk of fatal heart disease is by influencing the levels of cholesterol in the blood.
We don’t know whether there are other ways that smoking can increase risk of fatal heart disease. Maybe smoking can increase such risk through other ways besides cholesterol.
E
The risk of fatal heart disease can be altered by certain changes in lifestyle.
We know smoking, drinking, and exercise can influence blood cholesterol, which is associated with one’s risk of fatal heart disease. This strongly supports the claim that certain changes in lifestyle (related to smoking, drinking, and exercise) can change our risk of fatal heart disease (through changing our blood cholesterol).
