Is Levine's career finished?

Now resorts to sitting...

This just in from the Metropolitan Opera.  After continued health problems that prompted his resignation from the Boston Symphony, one has to wonder if Mr. Levine's days as a conductor are numbered.  It is unfortunate that such a storied career may have to end this way: almost akin to an aging athlete (are you reading this, Brett Favre?) who insists on coming back for one more season.  I can only recall the shock to the music world when Beverly Sills announced her retirement from singing, seemingly still at the top of her game.  Of course, she put her magical skills to work on the other side of the proscenium, guiding the New York City Opera, Lincoln Center itself and then the Met (assuming its chairmanship at age 73).  But such a fate is usually not seen in the conductor's craft; one usually simply fades away from the limelight....

May your recovery be a quick one, Maestro.
