On average how old is a 13-year-old?

Mathematics was never really my thing. I failed a couple of math exams here and there. So when I see a stumper like this one, I just have to sit down and take a deep breath:

On average how old is a 13-year-old?

Ok, so let’s see: If I add three and ten, divide it by fifteen, carry the one, shake my left hand three times, add the totals and then divide by zero, I’m fairly sure the answer is – wait for it:

Thirteen.
