Fair skin is a lot better than skin cancer!

People who work outside don’t get skin cancer. People who cook themselves for fun do. If they did, we would know, because workers compensation would be paying for it.

Yes, they do.

While state workers comp laws vary in ways which make this different from state to state, workers comp is paying for it for some subset of people who work outside.

Don't they?

"However, compared with the general population, the rates for certain diseases, including some types of cancer, appear to be higher among agricultural workers, which may be related to exposures that are common in their work environments. For example, farming communities have higher rates of leukemia, non-Hodgkin lymphoma, multiple myeloma, and soft tissue sarcoma, as well as cancers of the skin, lip, stomach, brain, and prostate."

Is it standard for medical papers to write values with four significant figures when they appear to have less than one significant figure worth of precision? This is an actual question.

Are you talking about the abstract or is there something in the actual paper you're talking about? Because I can't personally see anything in the abstract to suggest that the values quoted to 4 s.f. only have 1 s.f. of precision.

This article recommends around 100 nmol/L. Most people are between 20-30, because they don't get enough Sun and do not take supplements. It gets really really bad when the number gets below 10 and it takes months to recover. Another Vitamin whose deficiency cause irreversible damage is B12. Folks, get both of these checked.

Yet taking too much B12 increases risk for lung cancer. [1] [2] [1]: http://ascopubs.org/doi/abs/10.1200/JCO.2017.72.7735 [2]: http://edition.cnn.com/2017/08/22/health/vitamin-b6-b12-lung...

It's really hard to be confident in a study that finds an effect in men and not women, with no plausible explanation for the difference.

Related to this topic, if you have IBS/IBD, some interesting research been coming out in the last couple of years indicating that low vitamin D may play a role in this issue as well. This [1] 2015 study found 82% of people with IBS had low vitamin D levels relative to 31% in the control group. This [2] 2016 one proved causation of vitamin D supplementation improving symptoms, by randomly splitting into two groups and…

Thanks for this. I have IBS and began taking a 2000 IU supplement of Vitamin D awhile back for unrelated reasons. Maybe I'll bump it up to 3000 to see if it helps.

People who work outside generally do not do it in bare skin unless they are idiots (of which we have many, many, many examples). You don't typically see military folks wearing shorts and t-shirts even in the hottest weather unless they are out doing PT because the work they do can be harmful and so they use clothing to protect themselves. This used to be common sense. Why do bedouins wear long, flowing robes in the desert? Same reason.

My father, who worked outdoors most of his life, always wore long pants and long sleeves even on the hottest summer days. I did not understand why when I was younger. I now get it.

It seems dishonest to hide content that may be relevant to the discussion, especially after teasing it that way. Maybe if it warrants mentioning in your original comment it also warrants explaining why you think it's irrelevant?

There's no dishonesty. They are easily found for anyone interested. As I said the horse been has beaten to death so I didn't want to do what I was discouraging others from doing. They are mostly uneducated, lazy, decade-old, hand-wavy, and baseless personal attacks on him. The man has been a geek, engineer, programmer and a techie for multiple decades.

Jesus man, I think you overestimate the amount of people with an axe to grind against Steve Gibson and you're letting whatever negativity, real or imagined, majorly distract from your original comment.

Has anyone had experience ordering blood work (e.g. the vitamin d 25 hydroxy test) without visiting a doctor? I've seen very few references to the set of sites that pop up first online [0, 1, 2, 3] when I've gone looking for reviews in the past. Any suggestions? I'm in CA. [0]: https://www.privatemdlabs.com [1]: http://www.directlabs.com/ [2]: https://www.walkinlab.com/ [3]: https://www.health-tests-direct.com/

In case you have a health insurance - many plans provide a free yearly preventive care doctor visit, which include basic blood lab work. I took advantage of it many times with different insurance companies.

When I asked my doctor (in the US) for a vitamin D test earlier this year, he told me he would be happy to write the prescription but my insurance would most likely not cover it. He said so many people are getting it that insurance companies have started denying the claim unless there was a genuine medical need. I went elsewhere for it, see my other comment: https://news.ycombinator.com/item?id=15869485

No worries at all! I'm in the same boat. FYI some patience is needed as it apparently takes 3-6 months for changes in vitamin D input to make its way into the bloodstream and show effects [1]. I've just started supplementing 5000 IU as I get very low levels of sunlight. Fingers crossed that this helps the both of us.
