It's easy to understand why older civilizations worshipped the sun, especially those who live in the far north. "Will the sun stop it's journey this year or keep going west and leave us to die?" Winters must have been hard and miserable, hoping that there was enough food and fuel to last until spring.
I just have mild SAD, but I carefully watch the length of daylight and today, there will be 12 seconds less of it. Counting down to solstice.
Happy Festivus, everyone! And now, my favorite holiday song, Blue Christmas
