Speaking of eyes (the topic of my life's work for those of you new to this blog), let's start with....
Finding your blind spot.
Take a piece of paper and draw an X and a dot.
Close or cover your left eye and hold the paper at arm's length away while staring at the X. Slowly bring your arm closer.
*If you're having trouble, try drawing the symbols smaller and adjusting the distance of the paper to your face.
Wait, you've done that before? Hmph! Well, I betcha haven't figured out your dominant eye before (and no, it's not necessarily the same as your dominant hand).
Figuring out your dominant eye...
*If this doesn't work, make the same shape with your hands (extended fully) centered on someone's nose. Ask them to tell you which of your eyes they see through the hole in your hands. Whichever eye of yours they can see is your dominant eye.
Speaking of hands...
Growing a phantom digitTouch your forefinger to someone else's forefinger (or full palms) and run the thumb and forefinger of your other hand up and down the two touching fingers slowly.
(This was really hard to draw, sawwy).It should feel weird at least and at best, like their finger is yours!
If all else fails, at least you can pull out your knowledge of poodles or wombats or misquotations.
