Knowing nothing more than what I've read in articles elsewhere, to someone who's not going to have a child immediately, these kits provide information that is of limited use. For example, they might tell you that you have a 10% higher chance of developing a type of cancer which has an incidence of 1 in 10 (10%). Implying you're now told that you have an 11% chance of getting the cancer than the general population. Mostly, this is just going to get you stressed and not "prepare" you to face the slightly-more-likely cancer.
I suppose this might be useful to figure out potential genetic defects, but as adults, wouldn't most defects have manifested already (I'm speculating here, correct me if I'm wrong).
