Key word - "approximate." People ain't no statistics there, darlin'. Kids start to for basic abstract concepts around age 11, why not use that?
Um because it's not the largest sum of the population, dipstick. You clearly DO NOT EVEN UNDERSTAND STATISTICS, OTHERWISE YOU WOULD NOT MAKE SUCH STUPID CLAIMS.
Lemme explain it to you why, 16 is a good number...
1. It COVERS YOUR 12 y/o. And why? Because a 12 y/o is less than 2 (order of magnitudes) positions away from 16.
2. It also covers the 18 y/o. Same reason as 1.
3. BECAUSE DUE TO THE NATURE OF THE BRAIN 16 IS THE MOST COMMON SAMPLE AGE OF A MATURED BRAIN IN THE TOTAL SUM OF THE POPULATION IN REGARDS TO HEALTHY HUMANS. I typed that all in caps to just throw you off.
Either way, you lose. Because you're a fuckstick moron. gb2/sk00l and get edumakation.
