Alice and Ashley came across a locked door and a little pit padded at the bottom. Next to the pit was some sort of rope and a sign. It read "One stays behind and another jumps. A key to the door is found in the pit. The daring will be rejuvenated while the one who stays behind will stagnate."
Ashley said "what do you want to do? I mean who should jump?"
Alice said "You should. I'm bigger so if I were to jump you would be pulled into the pit with me most likely."
Ashley said "...but what if rejuvenate meant that I would get younger? this body is already pretty young and I don't want to be unborn because I jumped..."
Alice thought "what should we do?"
