By law, ingredients must be listed in descending order of weight. If sugar comes first, it's the product's main ingredient. Watch out for sugars split across several names, such as glucose syrup, dextrose or maltodextrin, so each one sits further down the list. Three seconds of reading in the aisle tells you more than the packaging.
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.
