Can i guess your age?

all the time I walk past people and wonder how old they are. I have developed a theory of guessing the age of many people by their behaviour. I walked around town guessing the ages of many people then asking them. most predictions were either correct or very close.

However, one girl I passed by looked very responsible and grown up. my EAG (Estimated Age Guess) was 15. I asked her and she replied " I am 11!". I was very interested in the fact that most females I passed by behaved in an older and more responsible way. Whereas, most males I passed by appeared younger than their proper ages. Thus shows us that most childhood females behave much more responsible than most adolescent and adult males.
