Ben Kenobi was right

So I just finished reading an article called Mind tricks: Six ways to explore your brain, originally posted on NewScientist back in 2007, which covers six different weird games you can play with your brain. Some of my favorite details are that:

1. You are blind about 3 times a second, due to the fact that your brain attempts to edit out jerky eye movements between images. You don't notice because (a) those moments of blindness are milliseconds long and (b) your brain will extrapolate from image to image and essentially "make up" what it thinks would have happened during the blindness. (Oh, and your sense of hearing does the same thing.)
2. You have a body-wide network of proprioceptive sensors that monitors your awareness of your own body. These sensors can be tricked, making you think parts of your body are stretching or even that things that obviously aren't part of your body really are.
3. Pendulum dowsing, no matter what you may think of dowsing as a magical art, is a functional way of interacting with your subconscious. And your subconscious is something of a racist jerk.
4. You most likely will not notice dramatic changes to your surroundings, as long as you are either distracted at the moment of change or the change happens quickly enough (or, oddly enough, slowly enough), or if you become focused on something else.
5. You can and will make up memories. And you will believe those memories are genuine.

The point? Does there really have to be one, beyond "hey, isn't this cool"?
