Document Summary

Physical development - physical decline, lifespan and death, sensory changes. These differences make up 3 stages of adulthood: early adulthood (roughly twenties and thirties, middle adulthood (to age 65, late adulthood (years after 65) In our peak mid 20s we reach a peak in the natural physical abilities which come with biological maturation: muscular strength, cardiac output, reaction time, sensory sensitivity. Middle adulthood - between ages 40 and 60, physical vitality (such as endurance and strength) may still be more of a function of lifestyle than of biological decline. Some changes are still driven by genetic maturation, especially, the end of our reproductive years. There is a gradual decline in sexual activity in adulthood, although sexuality can continue throughout life. Around age 50, women enter menopause(the end of being able to get pregnant) The aging body - the rise in life expectancy with declining birth rates means a higher percentage of the world population is old.
