I got a good amount of sun and vitamin D3 until at age 31 moved to Canada in 1969.
In Toronto we can not get enough sun and D from October to March.
Years latter found gums receding and 13 cavities, solved with large doses of vitamin C.
Latter found enamel erosion, cosmetic fixed with bonding...
Year 2000 had painful osteoartrithis bone and cartilage erosion, fixed with hip replacement.
Latter chest pain and shoulder pains was treated as stomach reflux and muscle pulled...
Year 2005 doctor finally and too late found lung cancer, lobe removed and chemo, cancer returns, radiation, returns, more chemo, returns, no cure available. I am 71 now and new research tells me that the problems were mainly caused by lack of Vitamin D!
Hispanics moving to USA from sunny countries get 40% more cancers.

Many common cancers, such as cancers of the colon and prostate, display fascinating north–south gradients, with rates that increase systematically with increasing geographic latitude, and show an increased risk among African Americans (3). The increased risk with residence at northern latitudes and greater incidence and mortality in persons with dark pigmentation recall the descriptive epidemiology of rickets, the classic disease of vitamin D deficiency. These considerations led several epidemiologists, including Garland and Garland (4) for the colon in 1980, and Schwartz and Hulka (5) for the prostate in 1990, to propose that vitamin D deficiency increased the risk for these cancers. Similar claims later were made for cancers at other sites, e.g., breast, ovary, and pancreas, so that vitamin D has become a prime candidate for cancer prevention Vitamin D casts cancer prevention in new light
Those trying to brand contaminants as the key factor behind cancer in the West are "looking for a bogeyman that doesn't exist," argues Reinhold Vieth, professor at the Department of Nutritional Sciences at the University of Toronto and one of the world's top vitamin D experts. Instead, he says, the critical factor "is more likely a lack of vitamin D."
