Emob78: There's lot of things you can't do at the same time. You also can't sneeze with your eyes open. If you could, you'd blow your eyes out and they'd go flying across the room. You don't want that sort of thing happening to your sale, do you?
Licurg: What if you hold your eye-lids with your hands ?
I suppose you could try it. I wouldn't dare those dark waters, though. You might try one, see how it goes. If it goes ill, at least you'd only be blind in one eye and could actually walk around with a cool eye patch. And if anyone asked you why you dressed like a pirate, you could tell them that some guy on the internet had challenged you to try sneezing with one eye open. Then they'd feel bad for you and offer you a treasure map for a very low price.
Emob78: You also can't sneeze with your eyes open.
JMich: False. It is possible to do so.
Emob78: If you could, you'd blow your eyes out and they'd go flying across the room.
JMich: Also false. Your eyes are secure in their sockets.
Not everyone. Some suffer from optical insecurity.
