Health news today spans both urgent human drama and longer-term public health insight. British boxer Raven Chapman remains in intensive care after collapsing during sparring in Denmark and suffering a brain bleed that required emergency surgery and a medically induced coma, with her family and the boxing world now focused on rehabilitation and a return home. In football, Celtic say Martin O’Neill is still in hospital after what the club describes only as a minor procedure, though an early discharge is expected. Boxing also saw Joseph Parker cleared to fight again after a cocaine-related suspension was lifted. Beyond the headlines, new research offers a quieter but striking message: avoiding smoking, diabetes and high blood pressure in midlife may add around 13 dementia-free years. And outside sport, the officer who shot Chris Kaba will face no disciplinary proceedings, with any further scrutiny likely to move to the coroner.
