That's life really. I mean, this is everybody. I mean, once I am at a point where I can no longer be productive or essentially better then the next guy, business will show me the door. That's coming for all of us, which is why any job that provides a retirement or long term care is so valued by so many. It's also why jobs like that force people to accept lots of things they shouldn't. People are deathly afraid of losing those jobs, for the most part, so they do anything. Its a vicious cycle but that's life right?
The difference is that for the average person, it happens over a longer period of time. For Athletes, it happens quicker because the window is shorter and the money is bigger.
