What is the most common birth date in the U.S.? According to data from the U.S. National Center for Health Statistics, it’s Sept. 9. In fact, September as a whole is a very busy month in U.S. delivery rooms. And, for those of you doing the math, that makes December a very busy month for, uh, other reasons.
Is there something in particular that makes December special, though? Could that possibly be our so-called “mating season,” even though we don’t, say, roar, pump out citrus scents or bash antlers to cue desire like other species do?
