The average woman has a period 520 times in her lifetime. That assumes 13 cycles per year at 28 days per cycle, and bleeding from ages 12 to 52. If the average woman uses 25 tampons per cycle, that works out to about $8 per cycle, for a total cost of $4,200. Add in the cost of panties that had to be tossed out because of an accident or two for another $1,000. Plus, another $1,200 for Midol. Now we have something practical to rally around in the upcoming election season - a tax break for having to menstruate.
