If you have ever known anyone who seriously works with chimps, you would know how easily this could happen. I used to work with a guy whose wife worked with the chimps in Downtown ATL. They made great breakthroughs in communication that helped people use electronics to communicate. The downside was that his wife was disfigured in the face due to an attack. Teh lady that ran the place was missing fingers due to the dominate chimp biting them off. These animals are very strong and have the mentality of a 2 year old. Imagine a pissed off 2 year old with that kind of strength. Very dangerous at times.
