You might not notice unless you push the daylight as hard as I do. Because I get up so early, I can feel the shrinking days by early January.
It starts with me oversleeping. I don’t use an alarm, so as the days get shorter, I find myself sleeping longer. Just by a few minutes at first, but by now I don’t open my eyes until 5.15 am, and don’t bother getting up until 5.30—the animals tell time by the sun and won’t look for me until then anyway.
At some point, I’ll have to switch to getting up in the dark. At some point, the days won’t be long enough.
But for now, I’ll enjoy the extra sleep.
