Can You Roll Your Tongue?

We’ve all seen dogs with their tongues hanging out of their mouths, but the reason why may surprise you.

This is because during periods of exertion or high temperatures a dog’s tongue increases in size as it exercises due to greater blood flow, and the moisture on the tongue works to cool this blood flow, thus cooling down the dog.

Our tongue is the primary organ of the human body responsible for our sense of taste; there are five elements of how humans perceive taste:

Salty
Sour
Bitter
Sweet
Umami (or Savory)

This is due to variations in size, width, and the amount of taste buds, making each of our tongues as different as a snowflake. The human tongue has on average 3,000 – 10,000 taste buds.

Although sticking our tongue out at someone could certainly be considered childish and offensive, in Tibet sticking out your tongue is a considered a greeting.
