When the power goes out, the golden rule is to keep the door shut. According to the USDA, a full freezer holds food at a safe temperature for about 48 hours, versus 24 hours if it's half empty: the frozen mass acts as a cold reserve. A refrigerator only lasts about four hours. After that, meat, fish and leftovers should be thrown out.
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.
