other then the phrase "knowing something like the back of your hand" the back of your hand has little use in our daily lives. why remember something as useless as the back of your hand, when there is no purpose to it in my opinion. as for the front of your hand (the palm) it has many use's, its very sensitive (for touch) its flexible (for griping things) ect. ect. in our society we tend to learn/ take in information that is useful to us, and disregard the information not relevant to us. much like the back of our hand, we tend to disregard all aspects of it.
