Be sure to know that you make no vitamin D when the sun is lower than 40 degrees angle. So.. when your shadow is longer than you, no UV-B reaches the earth, so no vitamin D from your skin.
@jakeacton72 derp, reading comprehension.. :P I saw sunsets and dawn, plus the mention of vitamin D. so I thought you had the misguided idea that long evening beach walks are a good way to get D.
