I tested a 600 ear-zapping device that claims to rewire your nervous system - and it boosted my memory skills by 80%

From the hunt for the philosopher's stone to the snake oil salesmen of the Wild West, the history of medicine has had more than its fair share of fraudulent'cure-alls'. So, when I first heard of a device that claimed to cure everything from depression to my rapidly deteriorating attention span, I was understandably sceptical. To make things even stranger, this potential wonder-cure isn't a pill, powder, or trendy new supplement. Instead, the Nurosym is a 599 gadget that claims to rewire your nervous system - by zapping your ear. MailOnline's Wiliam Hunter bravely tested it out - and, as strange as it all might sound, he's almost ready to believe the hype.
