Common Misconceptions: How many do you believe?

Some of these were taught to me in school so WTF.
-The Chevrolet Nova sold very well in Latin American markets; General Motors did not need to rename the car. While no va does mean "it doesn't go" in Spanish, nova was easily understood to mean "new".

I was taught it was because it was called "no go."

-Hand size and foot size do not correlate with human penis size, but finger length ratio may.
-The menstrual cycles of women who live together do not tend to synchronize. A 1971 study made this claim, but subsequent research has not supported it.
