• Answer:

  It's generally known that teenagers get little sleep, which may cause substantial health problems. Not only do teenagers suffer from sleep deprivation, but adults also experience this. In fact, "most working adults don't get enough sleep" is not an overstatement. Though detrimental to their health, many adults ignore sleep so as to focus their efforts on their long work hours. Fortunately for teenagers, work is usually not an obstacle to their sleep therefore they should seek as much of it as possible. Once one gets enough sleep, one will likely realize how important it is. Society as a whole can benefit from it's members getting the proper rest.
