Slow, dull, and G-rated
One can easily be unwell enough to train at a Worlds level (it was abscessed molars and a glandular infection, not tonsillitis) and still go to the Oscars. Going to the Oscars doesn't require hard physical labor.Part of the complaint issue with Tara was that the reasons she gave for her retirement, etc. often didn’t hold up. She didn’t got to Worlds because she was too sick with tonsillitis or something but shows up at the Oscar’s and celebrity appearances.
But it seems to have become a cherished tradition to question the motives and the truthfulness of every Olympic champion who pulls out of Worlds, as Nathan Chen could tell us. The truth is that skaters work for the Olympics harder than for anything else in their careers, and it's not surprising if the aftermath of that peak competition leaves them feeling unwell physically and/or mentally and not fit to train. And that ought to be enough for all of us. We may feel disappointed if they don't show up when and where we expect them to, especially if they had originally planned to. And it's okay to feel disappointed. But their first duty is to themselves and their health, not to us. And they're the ones who experience the symptoms and need to make the judgment calls.
