Bell ringing is a 'contact sport'

A 51-year-old man was winched down 80ft to the floor of Worcester Cathedral after being pulled upside down when his foot was caught by a bell rope.

He fractured a bone in his back but is still able to walk.

Mark Regan is the ringing master at the cathedral and tells BBC Radio 4's Today bell ringing can be like a "contact sport" and is all based on maths.
