Every new car model type-approved in the European Union since 31 March 2018 comes with eCall. In a serious crash, for instance when the airbags deploy, the system automatically dials 112, sends the vehicle's location and opens a voice line to the emergency services, even if the occupants are unconscious. An SOS button lets you trigger it manually too. The Commission estimates it can cut response times by 40% in towns and 50% in the countryside.
Chlorine on its own is fairly gentle. But when it combines with urine, sweat and other grime from swimmers, it forms chloramines, which cause stinging eyes and that classic 'chlorine smell'. A well-kept pool barely smells at all. Shower before you swim and never pee in the water.
Muscle mass slowly shrinks with age, putting independence at risk. But in 1990, a study had nursing home residents aged 86 to 96 train their legs for eight weeks: their strength more than doubled. Muscle responds to training at any age. Getting up from a chair without using your hands is already an exercise.
