Anywhere in the European Union, 112 connects you to emergency services free of charge, from a landline or a mobile, even with no credit and from a locked phone. Introduced in 1991, it works alongside national numbers such as France's 15, 17 and 18. If your own carrier has no signal, your phone can borrow a rival network for an emergency call. One number to remember for 27 countries.
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.
