For example, I am listening to the Memory supercharger in Mp3 format on my computer using headphones. (Don't worry I have my own personal copy of the tape.) I am listening to it on repeat over and over again... while surfing the net and doing whatever else on my computer... is this good? that one person that listened to this for 3 months 24/7 must have done other things in his days than just lying down... After 3 months of lying down.... your muscles would probably feel very weak.
