Don't forget the generally gray skies, barren trees, cold weather keeping us indoors, and the lack of vitamin D.
Our taxes are not due until April 15, but because we expect a refund, I am doing ours this weekend.
I don't know about the full moon and insanity. I do notice that I have to shave several times a day and my teeth get sharper when over the full moon is out. I seem to really like my meat extra rare then too.
