In this episode Dr. Bhatnagar  speaks with Professor Russell Grant Foster, a British professor of circadian neuroscience, the Director of the Nuffield Laboratory of Ophthalmology and the Head of the Sleep and Circadian Neuroscience Institute. "We have an internal biological clock, which is ticking away and essentially fine tuning every aspect of our physiology and behavior to the varied and indeed dynamic demands of the 24 hour rotation of the earth on its axis and the light/dark cycle."
