#WATCH# | Delhi: Dr Sriram Nene, Cardiovascular and Thoracic Surgeon and Founder of Pathfinder Health Sciences, says, "When we talk about being healthy, it often relates to how they look. The truth is, what's going on inside of you is something quite different... You have to look at all of the risk factors for disease: your family history, your social history, your eating habits, and what your anthropometric measurements are. If you have a strong family history of heart disease, meaning first-degree relatives- family members such as your mother, father, daughter, or sister- your risk of having heart disease is about 4 to 10-fold higher. Similarly, if you have other risk factors for heart disease, like high blood pressure, diabetes, morbid obesity, things like that, your risk is higher...

You should be looking at your exercise tolerance, what you're eating, and your overall healthcare..."
