[QUOTE]Originally posted by rasol: [QB] [QUOTE]Block Block (bl[o^]k), v. t. [imp. & p. p. Blocked (bl[o^]kt); p. pr. & vb. n. Blocking.] [Cf. F. bloquer, fr. bloc block. See Block, n.] 1.

This is how it protects against cancer from UV radiation, and how it limits the synthesis of vitamin D from said radiation. A perfect coating of melanin on the skin [absolute black] would -BLOCK- all UV from reaching the skin, and prevent ANY synthesis of vitamin D. This is why there is a trade-off involved, and this is why skin color varies in the 1st place. Too bad you don't like this fact and so refuse to grasp it. [/QB][/QUOTE]
