Which is more dangerous - boxing or river fishing?

In 1991, there was a boxing match that would change the sport forever. Chris Eubank was fighting Michael Watson; Watson was left with brain damage.

Peter Hamlyn is a consultant neurosurgeon, who helped save Michael Watson's life after he collapsed in that fight 25 years ago.

He told The World Tonight, which sports he considered to be more dangerous than boxing...and you might be surprised by his answers.
