Sorry about article 4997 - I've never posted an article before, so I
screwed up.  I'll try not to waste your time anymore.

In _The_Straight_Dope_, Cecil Adams explains that the reason women's periods
fall into sync is because of chemicals from their sweat: it seems that some
women are "dominant" in that their sweat causes other women's cycles to fall
in with theirs, and other women are more susceptible to suggestion from the
chemicals around them (I think these chemicals are pheromones?).  So if
women live together or work together for extended periods (no pun intended)
of time, their menstrual cycles will go in sync.
The Straight Dope is a highly interesting collection of trivia - I
recommend it even if you're not (like me) someone who generally likes trivia.

Hopefully this will be my first -successful- posting to the net.  Apologies
again about my mistake (I'm very inept with vi).
