And just like the proverbial free lunch, the hair is temporary. I've estimated before the amount of extra hair. Figure a person loses ~100 hairs a day. In pregnancy, say you lose (conservatively) half that. Forty weeks of gestation and that's in the neighborhood of 14,000 extra hairs waiting to take the leap. When the kid is 3 mo old or so, BOING! Hairs everywhere. And now you've still got the normal 100 a day popping off. Over a few months' time, the house, the car interior, and the office become abstract hair sculpture.
SNG won't store his hairbrush in the same drawer with mine. Because the hairs leap onto his brush. I just thought someone might want to know that.
