The 14-day right to change your mind under EU law covers distance purchases, such as online shopping, and doorstep sales. In a shop, no law forces the retailer to take back an item you've gone off: if they do, it's a goodwill gesture on their own terms. In France, the same goes for trade fairs, where there's no cooling-off period either, unless the purchase is financed by a loan. Check the returns policy before you buy.
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.
