Weber's law applies to perceptions. You can't really perceive time on a span of years. I'm pretty certain that human's can't intuitively distinguish 18 years from 20. My post asserted that people should use rough concepts of age categories but that those categories shouldn't involve representing age. Those categories should also not correspond precisely to our categories due to improvements in nutrition and disease burden, e.g. we go through puberty earlier, grow taller, etc.
