For quite some time, I've been amused that my wife can only wink her right eye. If she attempts to wink her left eye, it just ends up as a blink. (Obviously, I can wink both.)
Now that he's old enough, we've determined that my son can only wink his right eye as well. Searching further, my wife's sister and mom can only wink their
left eye. The mystery continues.
So, I hit the web. Not much information there; I only found
this rather lame forum post, which didn't really go anywhere. Google isn't finding anything more useful that that for me. So, I turn now to TFP. Can you wink with both eyes? Anyone know the science behind this? Is it genetic, or just random?
