I had slightly elevated cholesterol, Doc didnt seem worried, But I'm still worried about heart attacks, how likely is that I could have one? Or stroke

Time to address. You are not at immediate risk, do the following to help yourself. Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco in any form and do not drink.
