According to the National Center for Health Statistics of the CDC in a report released on (ahem!) my birthday this year, the average life expectancy in the US is 77.4 years (men and women, black and white, everyone tossed in the pot together).

Thus, if Mother is averaging 200 posts per month (and we're past that already) there will be 185,760 posts during her lifetime. I'm certain that with a little effort we could run that up to 250,000 or more -- after all, she's just about now starting to take her first faltering steps!
