How Relavent to your lives are the events of 9/11

 I don't remember the events of 9/11, so they aren't too relevant to me. I know some people might remember being in there classrooms or huddled around the TV, but I don't remember anything from 9/11. Though I don't remember anything from that day, the events are still relevant because they impact many things that we do differently now. Like  getting on an air plane, there is lots more security and processes that you have to go threw. Or like at school, they have security guards at the front door and the  doors outside are always locked. So, event thought I don't remember the events if 9/11, they are still relevant to me.
