Genetic Testing / Ancestry DNA

Genetic testing has become more popular over the past 5+ years and I'd like to get everyone's take on it. Is it used for nefarious purposes as part of the NWO agenda? Are there spiritual implications? From a health perspective I had some genetic testing done years ago which focused on genes related to lifestyle choices - cardiovascular system, energy/metabolism, etc. Considering your diet and type of exercise (or lack thereof) can determine which genes are expressed or "turned on" & "off", this information can help you focus on the lifestyle choices that help you stay healthy. Variations in your genes from what's considered "normal" might mean your body can't handle certain food/drink, e.g., some people aren't genetically able to metabolize alcohol very well; or that your body isn't able to extract optimal nutrition from food without taking extra B vitamins, etc. Long way to my point - I ordered Ancestry DNA's test kit over Thanksgiving (it was on sale!) because the last test I took didn't include some of the genes in the panel they now test. I haven't used it yet because I vaguely remember a comment someone made about the genetic information being used as part of the NWO plot. Anyone have any input on this? Any reason I shouldn't use it?
