  1. About a decade ago after seeing a graph in Scientific American showing UV intensity bands across the USA from Florida to Montana and corresponding sever disease rates, auto immune to cancers, sometimes 25 to 45% difference between the highest to lowest intensity solar influx (not counting skin cancer, more radiation yielded dramatically lower rates) AND considering the obvious fact that old cultures near the equator vs farther from it determined UV blocking effectiveness of our skin types, from dark to blond or even redhead (blocking UV to admitting UV, with the exception of Eskimos who get their D from seafood). I made D3 a part of my routine.

  2. About 1/10 of one percent. You can get D from diet too without skin aging and cancer.
