my family has a history of vitiligo (sp?) and my cousin who just visited has no skin pigmentation left. She doesn't hide it and went to my aquatics class with me. one lady remarked, "oh look how pale she is she must never get out in the sun." My grandmother had it too. Does this factor in with melanin being in the substantia nigra too? '

Admittedly I haven't read the articles in depth yet, but my other cousin, who is a nurse once told me about cancer pathways and how it spreads within a pathway.

So it sounds like they've got something going here. Another paradox.
