There are several theories about the aging adult and what successful aging embodies. A common theme for successful aging is well-being. Well-being in relation to health is represented and understood by the balance between one's emotional, social, spiritual, physical and cultural spheres. As demographics begin to change in our country, new and changing definitions of what successful aging means in our society are being developed through the research and practice of caring for those in the aging population. According to ("Healthy People 2020") "Older adults are among the fastest growing age groups and the first “baby boomers” will turn 65 in 2011. Over 37 million people in this group (60%) will manage more than a chronic condition by 2030.” Such a staggering number of aging adults comes with a great deal of responsibility in managing their aging process theories listed in our text regarding the health of psychosocial aging, the theory most in line with my idea of ​​successful aging is "Life Course/Lifespan Development", a theory developed by Back's theory suggests that as we age the roles in our life are altered in one way or another and our relationships also change As we age, their role may change: from a mother who raised the children for most of his life of having an empty nest and only caring for her significant other, of being a grandmother. Responsibilities are not necessarily removed, just slightly different. Moving again from the psychosocial to the biological there are several theories that try to conceptualize how and why the age of our body I am led to side with the programmed theory of Hayflick and Moorehead which suggests... half of the document... adult population according to a report funded by the Bureau of Health Professionals' National Center for Health Workforce Analysis, found that the older adult generation will be more racially and ethnically diverse, more educated, have greater access to information and these demographic changes may require more demanding health services than in past generations. This will require healthcare providers to identify key changes and adjust accordingly. In conclusion, I have discussed the psychosocial, biological, and nursing theories of aging that most align with and best explain my personal views on successful aging. I have also identified the changing demographics of the elderly population who will now and soon require healthcare, and the influences and demands this will have on healthcare workers in the future.
