What happened to the bones of the child workers because they stood for long periods of time?

The bones of the child workers likely suffered from strain and stress due to standing for long periods of time, leading to potential problems such as bone deformities, growth disturbances, and chronic pain. Over time, they may have developed conditions like osteoporosis or arthritis due to the constant pressure and lack of movement. Additionally, their growth plates may have been affected, potentially stunting their growth or causing misalignments in their bones. Overall, the physical toll of standing for extended periods likely had serious long-term consequences on the skeletal health of the child workers.
