1. Before another reminder
The reminder arrives while Mara is finishing a message. She dismisses it, promising to move after the next reply. The next reply leads to a spreadsheet, then a call. By lunch she has obeyed the software many times in one limited sense: she has clicked its button. Her working day has scarcely changed.
Mara is an invented example, not a patient, research participant or account of the author's experience. Her problem introduces the purpose of this book. A useful desk day needs somewhere for a change to fit. A reminder cannot create permission, suitable equipment, an accessible route or time between tasks on its own.
The UK's Health and Safety Executive makes a related distinction in its display-screen guidance: reminder software does not remove the employer's responsibility to plan suitable work and breaks [1]. The guidance belongs to its UK context; this book does not turn it into a statement of law everywhere.
We will build a small, usable plan around the actual work: what holds someone in one activity, what can vary appropriately, what needs support and what should be reported rather than endured. This is general information for adults, not a rehabilitation routine, clinical assessment or personal exercise prescription.
The aim is not to perform an ideal posture all day. It is to leave the day with more appropriate options and a clear next action. No expensive desk, fitness score or pain-free promise is required for that work to begin.
