I believe that the public health problem for vitamin D deficiency is quite significant. I would estimate minimum 25% of adults in the United States, Europe and probably even in Australia are vitamin D deficient.

I mean if you think about it, over 250,000 women in the United States will develop breast cancer this year. Something like 50,000 will die. If 25% of those breast cancers could have been averted, prevented in some way, just by having a little exposure to sunlight, would have been really tremendous.
