Definition: Defensive reaction of the immune system against certain substances or irritants.
Q: my student asked if you were pointing to your eye or your nose. Her allergic reactions cause her itch red eyes so she assumed she should point to her eye. I have always pointed to my nose - but perhaps either one would be correct depending on where the reaction shows up (in your eyes) (in your nose)?
A: The video shows pointing to the nose. But, it does look like pointing to the eye in a blurry moment. Interesting about a potential of the other sign.
