For anyone who has ever gazed enviously at a dog or a cat wishing that they might have a tail of their own to wag as they please, well believe it or not we have found the answer to your prayers.
A Japanese inventor has created the Tailly - a strap on tail for humans that wags when the wearer becomes excited.
The Tailly is fitted with sensors that monitor the wearer's pulse rate, so the faster the heart beat, the more it wags. When you calm down it swings more slowly.
‘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.’
