Sadly memory and recall are not my strong point. In fact I am surprised I even remember anything when I see how quickly it takes to forget things. How much of Hacker News do you remember?

The old adage of you remember 60% of what you read on day 1, 30% day 2 and 5% day 5. Within a day you are already suffering a painful decay rate.

Therefore any method to remember something (rather than nothing) is of importance.
