There’s one acronym that strikes fear into the hearts of all men: “PMS.” Now some savvy women have taken a biological condition and built a whole Web site around an effort to market their book, PMS: The Owner’s Manual. Why? They sum it up succinctly: “While PMS remains a subject most choose to avoid discussing openly, the reality is that the affliction affects nearly every person on Earth in one way or another. Even if one is not predisposed to PMS symptoms, chances are good that that person regularly interacts with someone who is, including sisters, relatives, friends and co-workers.” Amen to that sister. And the site is a compendium of observations and caveats for those stupid enough to ask, “Whatsa matta, you got your period?” Duck and cover, brother. Full details and wise guidance can be found at PMS Central.com.
