Early and middle adulthood involve significant physical, cognitive, social, and emotional changes. In early adulthood, individuals focus on developing relationships, careers, and identity. Physical health is usually at its peak. In middle adulthood, priorities shift to parenting and career goals while physical decline begins. Health risks increase so preventative care is important. Successfully navigating developmental tasks such as intimacy vs isolation and generativity vs stagnation is key to well-being. Late adulthood involves further physical and cognitive changes along with socioemotional adjustments. The aging process, death of loved ones, and changes in roles present challenges but can be positively addressed.
