   * % deficient globally is probably higher. - Appears that the population size was ignored - see reference #2 below
   ** Middle East: has dark skin and air conditioning - staying out ot extreme summer heat ==> colds in the sunner
It appears that Asia has far lower average vitamin D levels than Africa ( as well 3.7X more population)

Vitamin D Life
  1. Some groups in Europe believe that Vitamin D levels as low as 20 ng are OK
  2. Varous groups around the world believe that vitamin D levels should be much higher:
    30 ng, 40 ng or perhaps 50 ng see Vitamin D Life Is 50 ng of vitamin D too high, just right, or not enough

Vitamin D Levels continue going down in most places
