   For memory refreshing it is okay for people who studied chemistry before. But video needs to go into
   more details. So, audio and picture help us remember and retain longer in memory what we studied at school.
   Also, it is not a subscription, once you buy it, it is yours for life. What could be better?
   Thomas A. Edison was charging 5 cent per view, more than a hundred years ago, when he invented
   the kinetoscope (so called first movie machine). This one is yours for life, when you buy it once.

   It is good to refresh memory, retain longer and recall quicker, looks like having the event in your
   mind’s (inner eye). But, it could be matter better if the elements interact with each other alive.
   I’ll keep watching and listening until they become a habit (automatic).
   When we want to drive our car, we never look at the key hole. We just insert the key. Why ? Because
   It has become a habit (automatic).
