How do Everyman's ideas about good times change as he gets older?

Sins play a great role when a person gets older.

Explanation:

According to Everyman's idea during childhood age people don't pay much importance to sins because at childhood stage people don't understand the sins. But on the other hand when people grow up things become much more critical. People start understanding the things, they understand sins play an important role when they grow up. They need to understand all decisions should be taken efficiently otherwise we can suffer later.
