Rinsing raw poultry doesn't remove bacteria such as Campylobacter or Salmonella; only cooking kills them. What it does do is splash them around the kitchen. In a 2019 study by the US Department of Agriculture, 60% of participants who washed their chicken then had bacteria in the sink, and 26% transferred bacteria onto the salad they made next.
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.
