Samoa is moving in time

I'm off doing stuff tomorrow, so tomorrows interesting fact is coming today.

The country of Samoa, will be going to bed on the 28th of December and waking on the 30th of December.

They will not be sleeping a whole 24 hours, instead the country is changing time zones, moving itself officially from one side of the international date line to the other.

The idea is to help with trading with other countries, where they feel they are at a disadvantage.

Today’s interesting fact has to do with the Dogs and their sense of smell.

A dog's primary method of viewing the world is its sense of smell.

Dogs have 300 million olfactory receptors whereas a human only has 6 million.

A dog’s olfactory cortex uses about 12.5% of a dog’s brain, whereas that of a human is less than one percent.

Dogs can tell if a how long a scent has been on the ground and can easily work out which way a scent trail goes.

In effect scents give dogs a sense of time.

When I was young, I read Tarzan novels.

Tarzan, because he was raised by an unidentified species of great ape (can't be gorillas because they had a language) he was supposed to be able to use and process scents as well as a dog could.

But to do that, he would have had to have a massive restructuring of his brain and nose.
