In 2015, the International Agency for Research on Cancer placed processed meat in Group 1: it is established that it causes bowel cancer. Each daily 50 g portion raises that risk by about 18%. Note that the group reflects how strong the evidence is, not a danger equal to smoking. Keep bacon and ham as occasional treats.
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.
