again, we're arguing in circles because we are conceptualizing the analogies differently. our definitions of "career" are different.
oh well.
ca·reer
kəˈrir/
noun
1.
an occupation undertaken for a significant period of a person's life and with opportunities for progress.
There really aren't different definitions. It's a "work life", it doesn't include retirement.
Retirement, on the other hand, is the equivalent of the time between games (or after you quit playing games) when you have a static ranking from your previous play (maybe you're a retired world champion, say), that other people treat as a milestone in their own development—something to reach or to pass.
Now, if you said life, then sure, the endgame phase of that is retirement. But the early-game phase of that is when your parents are providing for you, and only extreme incompetence (or genetic bad luck) can cause you to "lose."
