Transitions can be confusing times but they are nothing to fear. Nothing can stay the same forever. What are the transitions in adult life?  Sell offers three main categories: young adulthood: choosing a vocation, the need for intimacy, courtship, romance, marriage, parenthood, being single; moral and faith development; middle adulthood:  midlife crises, vocational issues; physical changes, marital matters, grief; widowhood, dependent parents, and rebellious children; and older adulthood: attitudes towards aging, becoming a senior citizen; retirement, grandparenting, death of a spouse and institutionlisation. This is the whole spectrum of adult life.
