When we visit the medical profession (doctors, nurses, hospitals etc) we are usually asked a range of questions such as - does diabetes, heart disease, cancer, hypertension .... run in the family? To which we can usually answer back maybe one or two generations (siblings, parents and grandparents), but can you imagine being able to give the medics a complete family history - and I mean complete - actually no me neither. But it does raise some interesting concepts and questions.

Would you want to know whether a great aunt on your mother's side had died of some obscure disease and you were genetically pre-disposed to it?

More interestingly though perhaps - would you want to know if your children were genetically pre-disposed to some major risk? No, I'm not sure I would either.

But DNA sampling can answer some rather interesting and tricky questions. Namely who are you really related to? And do you really really want to know?

Are you willing to open the closets to find how many skeletons you have lurking? Then perhaps DNA can fill in the gaps for you.
