How Many Five Year Olds Could You Take in a Fight? How Many 90 Year Olds Could You Take in a Fight? How many little kids are you capable of K.Oing in a fight? How many elderlies can you dispatch in a battle?! Take the quizzes and find out! Apparently I can take on 25 five year olds and 20 ninety year olds. Lols that seems kinda pathetic.
