What is the greatest threat to having a heart attack, the nation’s number one killer? Ask this question and most people will answer it’s having high blood cholesterol. Or they respond, it’s due to hypertension, obesity, diabetes, or a stressful lifestyle.
But suppose you ask what things will improve the chance of surviving coronary attack? I’d predict that after some hesitation the answer will be having someone nearby to administer cardio-pulmonary respiration (CPR). But how many will know it depends on the floor you’re living on in a high rise building? And what should you know about the 26th floor?
