DNA Factoids are merely a conversational piece, or a "cocktail party" test, as we like to call it.

These tests are based on studies - some of which may be controversial - and results are not intended to diagnose disease or medical conditions, therefore not serving the purpose of medical advice. They are offered exclusively for curiosity purposes, i.e. to see how your result compare with what the scientific papers say. Other genetic and environmental variables may also impact these same physiological characteristics.
