A new smartphone app has been developed in Iceland that can be used to alert each of the country's 320,000 inhabitants as to whether they share a common ancestor with potential sexual partners. The "anti-incest" function allows users to bump their phones together to check their heritage against a central database and make sure they're not breaking any laws before knocking boots. All of which raises the question: was there anything about your former partners that you wish an app could have warned you about beforehand? Which nasty surprises could you have done without? It could be anything from bad breath to a secret lovechild.

2. “Bump in the app before you bump in the bed.”

That could solve all kinds of problems.

7. Just so.

Not a likely scenario for me either.

Charity begins at home.
Not anymore.
We've decided that I've become rather high maintenance in some areas.
