Some argue that death gives meaning to life, and that life without death would be duller...

Well, I've often thought of how my life would be easier if I could think of it with the same feelings I'd regard a video game with. Being too involved, can make things stressful, unpleasant, and prevent action, while being relaxed and knowing that the consequences of my actions won't mean the difference between life and death, would that add meaning to my life ? What amount of challenge and responsibility do we need ?
