forgetting curve

1. Well if i relate the Forgetting Curve to my life, I would say that it doesnt characterize me. It also depends because I consider myself to be a very organizd and responsible person. I even taught myself how to review my notes before for example going to precalculus so I could have a better comprehension of the topic and eventually long-term retention. In Readak, a technique has also been taught to us and that is of r=r which menas repetition equals retention. The more a student repets, in any way, his notes will eventually retain the information in his long-term memory. However I dont dismiss the fact that sometimes the information may seem overwhelming and the studying too exhausting, still i support the fact that if every student was to at least review or skim and skan through his notes daily, the learning process will be easier.
2. One question I have is regarding the topic about logs. I dont understand how is log, lets say with anothr base besides 10 important, beneficial or useful in our lives, or even in math itself?
