I don’t know why I started doing this as a kid, but it’s always worked for me as a simple way to remember something in the morning when I think of it in bed but don’t feel like getting up and hunting for some way to leave myself a note. It’s going to sound stupid but, like I’ve said, it does work.
All you need for it is your dominant hand and one part of your body — no, not what you’re thinking. In my case, I always used my right hand and my forehead, although I’ve tested it with my right hand and my left forearm and that works too.
All you do is this: Use your index finger to “write” out what you want to remember on your selected body part and after each phrase — i.e., as much as will fit — “wipe” the space with your hand and continue to write and wipe as necessary.
The important part is that your finger makes the shape of the letters and that your body feels it. It’s very similar to taking notes in class helping you remember what you were taught, whether you ever look at those notes again or not. The physical act of forming the words helps cement the memory in place for later. I always thought of the wiping part as pushing the words into my head rather than erasing them, by the way.
And sure enough, in the morning, the idea will pop back into your head all by itself. How do you think I reminded myself late last night to write this article in the first place?
