Salmon are born with the instinct to return to their freshwater birthplace to mate and die. Dogs are born with instincts - like my German Shepherd that needs to know where his humans are at all times. Sea turtles that hatch on the beach follow their natural urge to run towards the water. Humans, now there's a different lot.
I am not well read on the subject of human instinct but it seems we know very little of it. The only studies I've heard of, which doesn't surprise me, involve human sexual attraction. I do think there is one non-sexual human trait worthy of study. It appears in many of the human species born in snow country and is one I've found myself taking note of and checking in on frequently. It was happening this past weekend with the threat of snow storms and sub zero weather. What is this urge you ask? It is to stock up on bread, milk, eggs and toilet paper with impending bad weather approaching. Is this desire to make, consume and digest French toast during snow storms instinct or learned behavior? I'm going with instinct, pure as the driven snow instinct. That's my story and I'm stickin' to it.
