Fascinating

I just read this article and thought that this is interesting.   Researchers have done a study and concluded that eating chicken legs or drumsticks make children more aggressive.  They think that we should feed them food cut up so they are not necessarily biting the food.

How do they come up with studies?  What will happen when no one is around to cut up there food?  Will they grow up not eating food unless it is cut up? Will they hold up all of their pent up aggression ?
