Some experts say that DNA testing through biotech firms like 23andME does little more than collect personal trivia, that if you're really concerned about inheriting or passing on a genetic disease or condition, you should consult a professional genetic counselor.
I know several people who would rather not know if they are predisposed to genetic conditions (the "ignorance is bliss" defense) and there are others who are afraid that such information could be used against them (by, for example, a prospective employer).
And there are all sorts of questions of ethics and privacy that factor into all of this.
