If you don't mind, I'd like to add a question: I've noticed some Swedish people often say 'ya, ya' on the inhale. Is this something common across Scandanavia, excepting maybe Finland where the language roots are quite different? Is there some additional meaning I should take away from the fact that it's on an inhale? Just being casual? Something less than a definite 'yes'? Similar to the Japanese 'hai' that often just means "I've heard you"?

At least one enquiring mind would like to know.

Oh, aa someone from the US, I've never seen a grizzly bear. I've hiked in grizzly territory (Yellowstone) and made a point of wearing "bear bells" so as not to see one.
