Inventor creates tail for humans

A Japanese man has invented a tail for humans which wags when the wearer is in a good mood.

The 'Tailly' is attached to a belt with sensors which take the wearer's pulse. When their heart beats faster, it wags faster.

Inventor Shota Ishiwatari is convinced it will be a hit and hopes it will soon be on sale in Britain.

"Tailly is fun to wear to parties, while out with friends or playing with kids," he said.

"You could even wear Tailly on a date and express your true feelings through the wagging tail.

"Even better, your partner could also wear one, to add a level of subconscious communication between the two of you."
