I'm just asking out of curiosity, partly because I'm 11 years old and I'm wondering how many people of different ages there are. 

hmm, i want to answer, without making it clear what age i am, so lets just say im not not 3 + 1  years ahead of 3+4 years.

I'm -1 years old(I'm inverted).

im 13 (almost 14)

15. I'm also surprised at how many younger people there are
