your ignorance once again shines with your reply completely ignoring what was said. Everyone develops differently regardless of age compared to someone else the same age. hence why you see a lot of different extremes in both age groups. why do you think "jailbait" is a common term in our society? you must be extremely sheltered if you haven't met, or even seen a girl who is extremely overdeveloped "for her age" whilst being under 18, or even under 16. same goes for flat chested women over 18 -- a body type like Chloe Moretz -- who even get made fun of for not being as developed as other women around their age, body types identical to pretty much any model out there... and even they have different ranges.
different body types exist, deal with it.
and no one's referring to anime kid. maybe you should try getting outside once in a while and meet actual people rather than watching a screen all day.
