While on a visit to China a few weeks ago, I saw part of a TV program about a tribe (Chinese or Mongolian looking) that lived in the mountains. They would hunt on donkeys and have a eagle on their arm. When they spotted a wolf in the distance, they would dispatch the eagle. The eagle would land on the wolf's head and they rolled together on the ground. The next scene was of a dead wolf. Could the eagle have killed the wolf? (sounds unlikely) or maybe they just blinded it making it easy for the hunters to kill?

docs, did you go to med school because you like science (like human anatomy and such) or because you like helping people and being with them?
the same question for vets, did you study veterinary medicine because you like science or because you like helping animals and being with them?

one last question for both, could you give a percentage, like for example( I inetered med school because I like sciense 30% and because I like helping others 40%).

thanks in advance!!!
