Can you wink one eye, both or neither?

I tried while reading this, as I don't pay much attention to this stuff. I can wink both! ;)

Nope, I can't wink to save my life, never have been able to. It's my dad's fault, I got his none winking gene, my mum can wink perfectly well. She gave that gene to my brother! :p

lol i am so crap when it comes to doing that! just looks like am squinting to see! :o

I can do both...same speed
