I think you get the picture. Wasting time means wasting your life. Most TV wastes your life. You'll get fat TV encourages you to just sit there and let your mind more or less go blank. You pick up pounds sitting there night after night, not getting any exercise.
Obesity can lead to diseases later on in life.
Sitting there in front of the tube is not good for your health. Your mind will go numb While TV shows make great topics of conversation amongst friends, future admissions officers at colleges and universities and employers, for instance, will not be impressed with your ability to recite, alphabetically, the cast of your favorite TV show. They will want to know that you are an individual who is aware of the world around him or her. You will also become lazy by depending on this box to entertain you instead of being creative and inventive and finding ways to spend your time more usefully. TV can make you a dull couch potato.
