What do you think gets better with age?
Absolutely nothing improves with time, things change because of choice and experience and light of new knowledge. Movement of clock alone cannot make any significant changes if you don’t involve your mind, heart and learning to improve yourself.
I have seen old people doing foolishly, so I negated the believe that wisdom growths with knowledge. I have seen old men that are very restless, so age does not bring calmness or sombrreness.
Everything is a matter of choice and leaning.
