Forums IMPORTANT: PLEASE READ PhotoReading, Memory Optimizer what can I do during the "break time"?

Thanks for all the replies, I really appreciated it.
However, for Alex, as you mentioned in your reply "the 5 minute break from activation" and the "15 minute break".
I am sorry, maybe because my book was the older version or some other reason, I was not aware there were such "breaks" besides the 20 minute break. Can you explain more about this. ThanK you very much!!!
