Recently I went to Image -> Metadata -> Edit Metadata -> IPTC Extension in GIMP, and when I scrolled down I found 'Model Age', but with a 'Minor Model Age Disclosure' option underneath it. It's a drop down list with options from 'Age Unknown' to 'Age 14 Or Under' to 'Age 25 And over'. Why would I need to enter ages like that when I can just enter it in the textbox above?
