Looking back at the people I went to Highschool with and became teachers ... it's quite disheartening. It's only the people who did not grow up. The people who care about being "cool" and only thinking about clothing brands and gossip about teenagers as if they still were one of them. People who never did something more challenging than 12th class math. People who were too afraid of doing something in their lives.
I think this is an inherent bias. How could we possibly circumvent this?
