Every part of true lilies, genus Lilium, and of daylilies is dangerous to cats. A cat only has to lick fallen pollen off its fur or drink from the vase to risk acute kidney failure within days. The toxin responsible still hasn't been identified. If you have a cat, leave these flowers out of your bouquets, and if you suspect exposure, see a vet immediately.
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.
