Typical day of a HITMAN

You decide that taking the elevator can be quite risky as it is rather contained. And you think that jumping out the window is a ludicrous idea. You open your hotel room with your brief case in hand and your coffee in your other hand, you made sure that you left the 2 key cards in the room, seeing you are checking out. You glance at your clock and see the time is now 7:34. You walk down the hallway and open the stair way door, and begin to walk down. As you walk down, you being to notice you are short breathed. This is unlike yourself you are active Hit man and only 25 years old. You are on the 4th floor, and you begin to notice that you are unable to retain your breathe at all. You gasp for breathe and you are forced to stop. You sit and take some deep breathes, what to do now
