These categories are generally known as life course stages. A life course is the sequence of events, roles and age categories that people experience from birth until death. Life course stages are culturally defined, meaning we recognize which stage a person is in and have certain expectations based on that stage. The life course stages are often divided into three main levels of socialization:
Working out in warm water could be a radical new cure for high blood pressure, research shows. So-called hot aquarobics could even be a remedy for thousands of patients who do not respond to medication, scientists claim. The findings come from a study where patients whose blood pressure remained high despite trying at least three different drugs exercised three times a week in water heated to 32C (90F).
Swimming is beneficial in this regard not only because it can provide an aerobic workout, but also because the resistance provided by the water builds muscle, which helps with blood sugar control. Some other research has shown that swimming and water exercise programs can help people lower blood pressure.
