Very well thought out..
I'm only 16, and a female gamer to be honest. and I know exactly what you are talking about.
I have made many mistakes when I was 10, even more today. I have more experience than when I was 10, and I am probably still not mature now. I will have to say society DOES tend to choose the oldest person for a job or server staff position, And I will keep that in mind when I apply for a job hopefully this year.
Age does matter, so does maturity. and in the perspective of math and science... Age is the Independent variable here.
