The original chart release was by Pfizer (http://equineresources.com/pdf/pf_agechartrelease.pdf) and uses reproductive maturity as key points. Human spinal growth plate closure seems to continue at least into the late teens (http://www.spinejournal.com/pt/re/spine/abstract.00007632-200401010 -00010.htm; jsessionid=Hx4Nqx8TP1b3cbGdwQ4RShx6nf5GnRDq11rgZQFFXl2lrRSf8VSw! 1390229169!181195629!8091!-1), not too far off the horse schedule by the chart.
