To sneeze and burp or hiccup is possible to fart and burp at the same time is rare but to do all of them at the same time is anatomically impossible.
No it's not possible to the average person, but if you're daring to you can hold your eyes open but it is very hard.It would not be a good idea though. Trying to sneeze with your eyes open can break your rib cage or hurt a blood vessel. This also happens if you try to not sneeze.
No, I read somewhere that it is not possible to sneeze with your eyes open. :)
If you sneeze on a Tuesday, you will kiss a stranger. The whole rhyme goes: If you sneeze on Monday, you sneeze for danger; Sneeze on a Tuesday, kiss a stranger; Sneeze on a Wednesday, sneeze for a letter; Sneeze on a Thursday, something better; Sneeze on a Friday, sneeze for sorrow; Sneeze on a Saturday, see your sweetheart to-morrow.
No; it is not possible unless there are large amounts of blood that comes out of the persons mouth when they sneeze.
