exponential nature of forgetting

i have been informed by the passerby of a supermemo
http://en.wikipedia.org/wiki/SuperMemo
which lead me (inevitably) to the forgetting curve

the exponential nature of forgetting

if one have used the illustrator or photoshop, one is aware of their path curves, by adjusting the points on the curve, you adjust the curve itself if it is built by the bezier rules, it is organic, like us humans.

if the forgetting curve could somehow transcend into physical representation, the procedure of the current therapy would change.
the therapist could adjust your forgetting curve or the shape of your memory curve physically so it is aesthetically pleasant to your existence.
