There's just one flaw in your statistics JD. PMS rarely lasts only one day and can even last up to a week, so on any given day it is quite possible that 7 out of 28 women have PMS. You should be a lot more scared than you think!!!
Cog (who has PMS, a lousy life, thinks men are her biggest problem, has seriously considered both suicide and homicide, but luckily for you, the sharpest weapon I carry is my tongue!)
