An easy way of determining intelligence is to measure how quickly one becomes bored and in need of mental stimulation. Travellers become bored with their surroundings and crave new sights, sounds, smells, tastes and ways of doing things.

You’re right about smart people becoming bored quickly, you can tell what people are like quite quickly by how long it is before they want to move on.

And I guess that feeling of wanting to know what is over the next hill comes into it too.
