Would you want to know?

Genetic analysis of your saliva or blood can now reveal more about you than ever before - including your past, present and future health.

But it is a sensitive issue. Would you really want to know if a killer disease lurks, unavoidably, in your future? Or is it better to be prepared?

Now researchers are launching what they hope will be the biggest ever survey of public attitudes towards the issue, to find out what people think.

So what do you think? Know everything written in your genes, just some things ie conditions you may have without knowing but which are treatable, or just take things as they come.

It's a tricky one.
