Like fear stress is the fear of something that hasn't yet happened. One could add "And probably never will". Please note the word probably, that means it is unlikely to happen but it may happen. We could further define stress as time rushing up on us at a pace that is too fast for us to handle. There are three dimensions of time in most cultures; the past, the present and the future. Stress is suffered in the present but concerns the possibility of something happening in the future.
