I'm not sure I do, but it seems lots of people want to know what the future holds for them.

A personal DNA testing kit that could detect whether you are at risk of breast cancer or heart disease is now available in the UK. It analyses DNA in spit to identify genes linked to certain diseases.

The kit is controversial. Experts are concerned over the accuracy of its results.

I think people should be able to use the kits if they want, but they should go and see their doctor first if they have any serious health concerns. Personally, I don't want to use it.

Concerns have also been raised about whether the makers of the kits will sell people's test results.
