My daughter's doctor says almost no one in the northern hemisphere gets
enough vit D in winter. The rays are too low and the days too short. In
summer 20 minutes every few days will do you.

She had to be treated for severe VitD deficiency this year due to her
dermatologist's insistance that she wear sun block at all times. Doc still
insists, but kid now leaves the back of her neck unprotected.
