Not only is sleep good for you. Lack of sleep is bad. It even causes measurable brain damage. They taught us in medical school that you don’t make new brain cells. Totally false. You need to make up to 10,000 new brain cells every night. So whatever you do, make sure you sleep well tonight and every night.
