That is total crap from Dr Tarehan. He himself is a smoker. Second, like all doctors he has the illusion of being a scientist, convienently forgetting that essentially a surgeon is no better than a car mechanic. Instead of car engine, he finds problems in human heart, and robotically fixes them - albeit human body is far more complex, hence requires 5 years training minimum. Thing is, we value our lives more than cars, therefore, give more value to doctors than car mechanic. Just like the stutus difference we preceive between a bus dirver and airline pilot. Second, all the latest medical research on average is already 5 years old before they become part of doctors day to day practice (recorded fact). Take for example the research on oils. It has been emprically proven now that cold pressed olive oil, unrefined mustard oil (the villagers use) are acutally good for heart - better than all the saffolas etc we city people consume after listening to TV ads! Even desi ghee and butter are good for your heart and general well being, if you are very active physically like a farmer! Thanks to the internet and swift communication, this 'consult your doctor before ' kind of doctor&pharma company nexus is on its way to disintegration.
