    Thanks for pointing that out.

    In the winter, only 10 percent of the body is exposed, and nearly 2 hours of sun exposure at noon is needed to produce a sufficient amount of vitamin D.

    I thought less time was required.

      So I’m supposed to be outside for two hours in -20 degree weather to get my Vitamin D just so I can survive?
