Shakespeare once talked to us about the importance of sleep in our brain’s maintenance and health through a Macbeth’s speech:
Sleep that knits up the raveled sleeve of care, the death of each day’s life, sore labor’s bath, balm of hurt minds, great nature’s second course, chief nourisher in life’s feast.
Shakespeare was an enthusiast of neurology and knew the repairing effect of sleeping in learning and how insomnia can make your health and memories suffer quite a lot.
