People who are keeping a tab on calories are often worried about how much they consume everything something is eaten.

But did you know that licking a stamp can even give you calories?

Though it might not be much compared to the other fast food that we consume on a day to day basis, but licking a stamp can make you consume around 1/10 of a calorie. So next time you decide to send a post card to someone remember that licking a stamp is similar to eating a very tiny snack.
