The WHO recommends keeping saturated fats, found in butter, fatty meat and palm oil, under 10% of your energy intake. Replacing them with unsaturated fats, such as olive or rapeseed oil, nuts and oily fish, lowers the risk of heart disease. The goal isn't less fat, it's better fat.
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.
