The team explores things that could be threatening people on a daily basis. Liz Bonnin finds out why pedestrians of a certain age may never be safe crossing the road, Maggie Philbin remembers former footballer Fabrice Muamba's miraculous survival a year after he had a cardiac arrest on the pitch - and asks how many other young people are in danger of suffering a similar attack. Jem Stansfield reports on European legislation to make rear-facing seats compulsory for more toddlers, and there's a report on a revolutionary new burns dressing that could drastically reduce the risk of scarring.
