Are people under the false impression that they are staying healthy and fit, when they do jogging in spite drinking alcohol and smoking?

Impress Yourself.: Be careful when interpreting impressions, false or otherwise. A patient of mine, gave the impression of perfect health. He was lean, mean, exercise machine. He did not smoke or drink alcohol. He was self made, well off and loved by a lot of people. One morning he failed to show up for work. When his staff checked on him, he was found collapsed and unresponsive on his Stairmaster. Go figure.
