Some Sun each day just going about, but no sun bathing.

Texas has lost its vitamin D sun - the sun's altitude has to be 50 degrees altitude or over [midday], otherwise the D rays bounce off the atmosphere.

You need 15 minutes in the sun when its altitude is over 50 degrees to generate your D for the day.

Australia is getting stomped because it's winter down there, and they ain't getting no sun D.
