there is a couple of ones that I'd like to call bullshit on... all body functions stop when you sneeze.. bull shit, total bullshit. half bullshit on Alfred Hitchcock.. cause that is how we survive in the womb, but I guess it could be possible, but I doubt it. and idk if babies are born with or without knee caps but I know I have a 4 and 5 year old that has had theirs for a while. and 7% of people are lefties... I think I know more left handed people then right handed.. not that there is more in general but I'm pretty sure lefties are more common then 7%.
If your heart stops for a few seconds during a sneeze you would not have a heart attack....other wise people with heart stutters and irregular heart beats where their heart skips a beat would be having heart attacks all the time.
first.. i can still drive when i sneeze so not all body functions.. and second i have some heart issues and even a second of my heart stopping i would at least notice it.. But those two is not the definite reason i know this is bull.. it is because my sister-in law is still alive. when she sneezes she does it over and over and over... and over and over and over.. you get the picture, and there is not much more then a half a second between each sneeze. she would be dead if her heart stopped every time she sneezed.
Was bored so i looked it up. I was wrong about the heart stopping (I can freely admit that.), BUT apparently the myth originates from the fact that when you sneeze, the pressure in your chest can change your blood flow. It can actually cause the heart to skip a beat. Not stop..but that's what people thought was happening back in the day.
