I wake up before my Wife. I have never needed an alarm clock. It's dark when I get up winter or summer. "IF" she has to get up early and it's still dark it freaks her out to this day that I'm in my chair drinking coffee in the dark no lights. She has begged me to stop doing that when I retire (FRI 29MAY26)....but I don't think I will be able to. I'm just more comfortable in the dark. Sometimes I will sit out on the deck and watch the sun come up if I have time, and listen to the deer, fox and other critters wander through before the sun and the birds wake up the woods.
I'm not afraid of the light....the dark is just more relaxing and I think better in it.
