Katherine Grainger 'finishes PhD studying psychopaths'

Olympic rower Katherine Grainger has reportedly finished a PhD focusing on psychopaths.

The 37-year-old has completed the doctorate on 'the whole life order', which is the sentence given to psychopaths considered to be too dangerous to be released from prison.

Grainger did her PhD at London's King College, where she was given a Fellowship, according to the Daily Star.

Grainger, who won a gold medal at the London 2012 Games, also has three Olympic silver medals to her name.
