The medical benefits when one knows their ancestry can be life saving. To assume ancestry based on skin color is a danger to one's health while laying in a hospital bed. An illness can be the result of an inherited trait that is unidentified because of a hidden ancestry. This is a problem faced by Diasporans in particular who tend to have many mixtures unknown to them as well as those who are adopted or abandoned by parents unknown. Spread the word and possibly we can save lives!
