I forget


19th century psychologist Hermann Ebbinghaus [1850-1909] developed  the "Ebbinghaus Curve of Forgetting." It revealed that the average person immediately forgets 56 percent of new material learned. Within one day, the percentage climbs to 66. Within one month, we've lost 80 percent of what we've learned.
