Sleep deprivation is a prominent problem in the United States, and studies have proven that fatigued drivers can be just as dangerous as drunk drivers. I have not performed heavy academic studies on this, but from personal experience and logical reasoning I believe that a paraliminal tape designed to help people fall asleep would be very useful and effective.
Personally, my parents often have difficulty with falling asleep. I do not share in this problem; I can often fall asleep within five minutes of going to bed. I remember that when I was a little kid in elementary school, if I ever had difficulty with falling alseep I could think of a sequence of events and I would be able to fall asleep in approximately one minute. (Oddly enough, I thought of playing a fast-paced video game called "Sonic the Hedgehog".) I have also used "Memory Supercharger" as a technique for falling asleep by recalling the audio used to place people in a state of hypnosis. For me, it works effeciently.
What do you think?
