This is my understanding of entropy using oxygen particles as an example. You're impervious to aging, disease, hunger etc. But you still require oxygen to survive. You're sitting in a room with a constant supply of air - just as you are now - given enough time, say trillions of years, you'll suffocate to death because at some point the oxygen particles in the room will accumulate in such a way (say, in the corner of the room), that you will not be able to breathe. This seems utterly illogical to me. Or have I misunderstood the concept?
