The advice to listen to your body assumes the body reports in real time. In some conditions, it does not.
The warning that would normally say stop can arrive hours or days after the limit was crossed. By then the activity felt manageable and the cost is already due.
This is why pushing through can feel fine in the moment and expensive afterwards — the signal lagged.
The delay is worth reading for, because a late warning system changes how capacity has to be understood: planned for, rather than felt for.
