Why do I Choose gorilla out of many kind of animals?

 When I was a kid, I watched a movie, which I forgot its title but it doesn’t seem so important. The movie displayed a doctor which discarded the limbs of a man’s body a replace it with mechanical limbs. So, I thought, why should replace it with mechanical things? Why don’t replace it with other man’s limbs or take animals part? I started to think, if one’s are to replace his or her hand with animal’s limbs, which animal should he or she choose. And I started to think. What kind of species which have both hands like human? Then my mind said it is primate. Then to think of it I choose gorillas as gorillas are the strongest primate in the face of the earth. Starting from that, I love to know more about gorilla, or rather, gorillas’ strength.
