I wish I didn't know that tonight's full moon will be the biggest of 2009. It makes the whole year feel downhill!

The moon is moving away from us by about 1.6 inches (4 centimeters) a year. Eventually, this drift will result in  the moon taking 47 days to circle our world. Will women's periods lengthen to 47 days, too? Stay alive and see. It should only take, oh, a million or so years.
