&gt; Age is unrelated to wisdom and I&#x27;m talking about the full experience.<p>That&#x27;s not true; age and wisdom are quite related, just not directly causal.  They are correlated. Older people are generally wiser, it&#x27;s just not a guarantee, nor is it impossible for young people to be wise, but it&#x27;s certainly far less common.  With age comes experience and with experience, wisdom has fertile ground to grow, though it doesn&#x27;t always.
