Rules are for Guidance
After being told about the rules by experts we should try to follow them. However we are all individual and what works for one person may not work for someone else. Some people advocate television in their rooms, saying that when playing quietly it lulls them off to sleep. Others say that reading a book relaxes and settles them, yet some experts may point out that a book can stimulate the brain, just at a time when it should be settling. Size up what works for you.
