Knowing your ancestry may save your life.
Tracing the Tribe just posted "New Mexico: Secret ancestry, hidden health risks" which covers the ramifications of knowing one's ancestry. While it covers the search for Jewish ancestry by individuals, it also focuses on breast (and other forms of) cancer resulting from the so-called Ashkenazi breast cancer gene mutation. This identification is wrong, as the gene is Jewish, dating from 2,000 years ago, long before there were Ashkenazim or Sephardim.
There are links to some interesting video interviews, to the New Mexico DNA Project at FamilyTreeDNA.com and to additional genetic information.

The bottom line: Knowing your ancestry can save your life.
