Giving and receiving a hug is 9/10 (don't try hugging a hedgehog, it won't end well) a lovely feeling. We all need a good hug from time to time, but distance can sometimes be an issue.
Let someone know that you're thinking of them by sending them a virtual hug! Although it's not quite the same as a big cosy hug, it will still bring a smile to their face, because they'll know that you're thinking of them.
Sending a virtual hug is easy if you have Facebook, for example, log on and type "Hugs" in the search bar and you'll see some apps that will allow you to send your very own virtual hugs to someone you think needs one.
It only takes a few minutes, but it's the little things that get us through the day.
This cost benefit is calculated based on information about how much people are willing to pay for a hug per minute, multiplied to give an overall value for a virtual hug for a few minutes as the equivalent of a real hug.
