It snowed for a few minutes just now. The sky is dark and it may snow again. It would be funny (haha) if the snow came down and blanketed the earth so late in the winter.
I was just thinking to myself yesterday or the day before that the tide has turned and now the temperatures are rising. I think it was 11°C when I was thinking that. For those on the Fahrenheit scale, that is 52°F.
Here in Edinburgh, 56° north of the equator, every beam of sunlight is welcome. The authorities are so worried about the lack of sunlight that they are thinking about adding Vitamin D to food. Rates of some diseases that are thought to be exacerbated by a lack of vitamin D are higher in Scotland than in England.
Vitamin D – Prohormone
Vitamin D is a group of fat-soluble secosteroids. In humans, vitamin D is unique both because it functions as a prohormone and because the body can synthesize it (as vitamin D3) when sun exposure is adequate (hence its nickname, the “sunshine vitamin”).
When we look at what a prohormone is, we can get a better idea of why vitamin D is important in the body.
A prohormone is a substance that is a precursor to a hormone, usually having minimal hormonal effect by itself. The primary function of a prohormone is to enhance the strength of the hormone that already occurs in the body.

On Being A Nomad
Having lived and traveled in various places, I sometimes think that by moving I am keeping one step ahead of whatever the prevalent problem is in the region in which I am located.
It might be radon radiation escaping from the ground rock. It might be insect-borne diseases. It might be lack of selenium in the earth. It might be lack of sunlight.
It is a powerful argument for being a nomad, don’t you think?
