After a doctor told him to get more exercise, this man unearthed a treasure trove that's been called the 'find of the century'

• Erlend Bore needed to get more exercise, so he bought a metal detector and started walking more. 
• He found what he thought were chocolate coins, but they were gold jewelry from about 500 AD.
• Bore's discovery has been dubbed the "find of the century," but he can't keep the treasure.

A Norwegian man who was just trying to get some exercise has unearthed gold jewelry that's about 1,500 years old.

Earlier this year, 51-year-old Erlend Bore bought a metal detector after he was advised by his doctor to get off the sofa and find a new hobby. He started walking around his home in Rennesoey near Stavanger in southern Norway, mostly finding scraps of metals and the occasional modern coin.
