This fascinating interplay between genealogical study and health – and the benefits and potential pitfalls involved – is the topic of this week’s episode of my "Newt’s World" podcast.

While not every disease or chronic condition has a genetic link, many do. Knowing what illnesses to which you may be genetically predisposed can potentially help doctors get ahead of your condition and lessen its impact with preventative treatment.
