&gt; “Chronological age is not a particularly good indicator [of maturity], but it’s something we need to do for practical purposes,”<p>This may be anecdotal, but I&#x27;ve found a very strong association between age and maturity in my life, especially under 25. If you were to do a blind chat with a 10, 15, 20 and 25 year old do you really believe you wouldn&#x27;t be able to place them accordingly?<p>But maybe this is just my own biases deluding me. I&#x27;d like to think I&#x27;m a better man than I was 5 years ago, and will continue to be a better one 5 years in the future. Then again, is maturity really defined as being &quot;a better (wo)man&quot;, because according to dictionary.com it&#x27;s defined by age.<p>Either way I&#x27;d be curious for that professor&#x27;s full quote. Maybe if we could replace &quot;[maturity]&quot; with what she actually said it would shed some insight on what exactly we&#x27;re talking about.
