What help do you have to provide if you are seated in the emergency row and there is a situation?
When sitting at the exit you need to be the first one out of the plane. Basically when the emergency is declared and the captain says, Evacuate, Evacuate, you go to your door, check the outside for fires. Then you open the door en be the first one out of the door. You then put as much distant between you and the plane as fast as possible. Or you assist on the outside of the plane by making sure people create enough distance between themselves and the plane.

What could with hold them from sitting there is the responsibility to get the door open. Or the fact that they enter a shock and will be unable to move during an emergency.
