By now, you’ve heard the news that former Giants first baseman/outfielder (?) Aubrey Huff has announced a new career as an actor. Plenty of professional athletes have attempted this sort of post-career move and I applaud them for it. Being a professional actor and being a professional athlete have many similarities, and the former in some ways prepares one for the latter.
They are single-focus occupations that lavish attention on the individual for the purposes of make them look as good as they possibly can for the larger benefit of some group goal (winning in the case of sports, making a thing in the case of acting).
