MRCOG revision is a long-haul endeavour. It is not a sprint; it is a marathon. Your diet and physical health will have a direct effect on your cognitive abilities. Don’t chance it. Eat healthy – lots of fruits and vegetables, nuts and lentils, and some lean meat and fish. Cut down on processed meat, fats, sugar and alcohol. Regular exercise, incorporating some key stretches (particularly of the neck and shoulders), is a must. Finally, you need to have regular stress management strategy, for example, yoga, listening to music, spending time with friend and family or watching comedy.
