George Schaller: Actually, you know, I’m more worried about studying a bear than a tiger because a bear, its facial expressions are not as clear-cut as a tiger.  You know what a tiger is thinking, but a bear, more difficult.  So you have to decide what is best to do with these animals.  And, for example, the tigers, where I worked in Central India — I was out all the time walking around.  I’d meet the same tiger again and again.  I’m sure they recognized me.  I wore the same dirty clothes all the time.  So again, the animals learn, “Hey, this guy’s no problem.”  So they don’t make it a problem.  In fact, they don’t necessarily run away.  I’ve had them crouch ten feet away while I walked past and purposely not look at them.
