A thought-provoking report from the Royal Society for Public Health (RSPH), titled *Playground Rules*, warns that if current trends continue, 41% of children aged 10 and over could be overweight by the year 2035. The report advocates for a comprehensive 'whole school' approach to physical activity, calling for reforms in Ofsted inspections and physical education funding to enhance youth engagement in exercise. This strategic shift aims to involve schools and broader public sector collaborations to foster healthier habits among children.
