Remember my cousin who worked at a shoe store. He said people would come in with totally flat feet after years of jobs like that. Makes you realize how much our jobs can really wear us down.

What did you end up doing? I swapped my hard floor wheels for rollerblade style ones after reading a thread like that. They roll over carpet way better and don't leave marks on my hardwood.

That's a cool example with the NOAA data. Makes me wonder about other fields where the training data is everything. Like, have you seen cases where someone used a model trained on legal documents versus general web text for contract review? Or maybe medical journals for diagnosis help versus a base model. The gap must be huge for stuff that needs exact wording or specific facts.
