Middle aged adults have more intense concentration for rapid judgements like driving a car. Hard to find direct relationship between age-related brain differences and cross variation in behaviour. Cessation of period due to decline in sex hormones. Periods irregular due to progesterone loss: perimenopausal phase. Estrogen and other hormones change and decrease. Estrogen loss effects genitals and other tissue (breasts less firm, genitals and uterus shrink, vagina wall thinner) Alternative lifestyle encouraged (exercise, diet, stop smoking) Prevent by calcium intake, weight bearing exercise and tests.
