In this study, the raw data were first coded through basic coding. Then, eight organizing themes emerged from the existing codes. Finally, the global theme of dynamic aging was extracted by integrating the organizing themes.
4.1. Marital Satisfaction with Life
In this study, the elderly were found to have experienced satisfaction with their marital life during their life with their spouse as one of the organizing themes related to healthy aging, causing a feeling of pleasure and satisfaction with life. This organizing theme included some basic themes such as a good-natured husband, a responsible spouse, and companionship in life. Although some of the participants’ spouses were not alive, one of the reasons they were satisfied with their current life was the spouse and his/her memories. The participants talked about the spouse who has kept up for years, respected him/her both in public and in private, been good-natured, strived to make money legally, and tried to make his/her family happy. For instance, a 68-year-old woman said, "I was satisfied with him since the first day because, God bless my husband, he was very good-natured, calm, and did not hit me. Every moment of my marital life was good. He did everything for the family. I was respected in public and satisfied at home with this life".
4.2. Satisfaction with Moral Issues
The role of children in Iranian culture is crucial, and the elderly seek support, especially from their children. In this study, the elderly expressed satisfaction with their children and support. They referred to issues such as children's respect for the elderly, consultant for children, physical and mental health, moral and social health, loyalty, education, and parental appreciation. For example, a 65-year-old woman stated, "All of my children are educated, and I am satisfied with them. I have six children, all of them have master's degrees, and they are all healthy and non-addicted. They live their own lives". Another 71-year-old man said, "I have ten children, and they are all fine. They are not addicted; they have respected me and their mother. Well, it makes me satisfied with life".
4.3. Healthy Lifestyle
The elderly should have a good lifestyle, consisting of a set of appropriate behaviors and habits observed in all interviews to achieve healthy aging. Nutrition, exercise, non-smoking, regular medical checks, and weight loss are some of the basic themes incorporated into this organizing theme. These habits and behaviors seem to help the elderly prevent diseases such as heart attack and pneumonia. A 65-year-old woman stated, "Every two or three months, I visit a doctor, and the doctor prescribes some tests. I go to Isfahan to do the tests. I do this so that if I have a problem with aging, I can stop it quickly". In addition, a 68-year-old man advocated that "I exercise from Saturday to Wednesday, I go to a club to exercise. Then, I do the same exercises at home on Thursdays and Fridays. At 7 o'clock, I go for a walk. Then, I come here to the daycare center. I generally go to the park for a long walk".
4.4. Spiritual Orientation
Old age is a critical time when religion fills the voids in life and even makes it meaningful. A religion can be an essential source of hope, comfort, and peace during every stage of old age in a complex economic, social, and psychological environment. Interviewees discussed concepts such as praying for health, trusting in God to solve problems, creating calm, receiving healing from God, coping with stress, reducing negative thoughts, and reducing loneliness. People with chronic illnesses, especially the elderly, seem more inclined to turn to a higher power for help. For example, a 66-year-old woman whose husband had cancer for many years said, "Doctors operated on seven or eight parts of my husband's body. We went to Isfahan for a few years and did chemotherapy. My children were all upset every time they came home. I said this was God's will. Trust in God; he would be fine. I asked my children to pray for him. I asked God to help me".
4.5. Elderly’s Independence and Financial Self-sufficiency
A second organizing theme identified in this study was financial independence and self-sufficiency in the elderly. The elderly are independent in the sense that they still manage their own lives, and do not feel that they have no authority or role in making decisions as they age. In addition, the participants used the term independence to show that they can perform tasks such as daily activities, dressing, shopping, and visiting the doctor's office. In fact, the elderly wanted to point out that they do not like to be a burden on their children and family by referring to the term independence and feel pleasant and positive. In the interview sessions, a 71-year-old man stated, "I thank God that I am physically healthy. Although I have diabetes, I walk and do my activities. I'm satisfied. I'm not paralyzed. I make my food; I help my wife in the house choirs. I'm very pleased that I'm behaving in a way that everybody respects me".
Similarly, a 72-year-old woman advocated that "I am old now. I am satisfied that I am healthy. I can do my daily chores. I do not need my children and do not want to ask them for help". Moreover, the elderly highlighted financial self-sufficiency, meaning that they did not want to be financially dependent on their children and desired to meet their own needs independently. One of the fears the elderly mentioned was financial dependence, so they preferred to have financial independence rather than expensive equipment and food. There was a possibility that their children would not financially support them in these specific economic conditions. For instance, a 73-year-old man mentioned, "Financial issues are important for the elderly because if they ask their children for help, they may not accept and may tell we have our own life".
4.6. Intra-generational Dynamism
Dynamism within generations was another organizing theme, referring to the notion that older people do not have a close or distant relationship with their peers and have very dynamic and active relationships. These dynamic relationships within the generation are important during this period when work and family responsibilities are reduced. Many participants stated that they enjoyed spending time with their friends more than with family members because they shared enjoyable activities and leisure time together. When the participants were asked to describe their friendships and intimacy, they referred to shared tendencies, feelings of belonging, opportunities to share secrets and talk about their memories, and group walks. The participants believed these relationships would be strengthened that over time and seem to protect the elderly from the negative judgments of others about their abilities and values as human beings. For example, a 63-year-old woman said, "Another thing that comes to my mind is the fact that we are delighted when we are together. When we go to a class and gather, bad thoughts disappear. It's better to be together than to be at home because we feel lonely there".
4.7. Intergenerational Dynamism
The participants named their relationship with their children and grandchildren as another issue, which affected their health. Relationships between grandparents and grandchildren can make grandparents feel efficient and appreciated the value they receive from their grandchildren. In addition, this relationship creates a sense of self-worth and efficiency and eliminates loneliness. The basic themes related to this organizing theme include visiting grandchildren and children, inviting family, spending time with families, sightseeing with grandchildren, taking grandchildren to the park, telling stories, and calling grandchildren and children. A 68-year-old woman stated, "I'm pleased to see my granddaughter. She comes to my house two days a week. She blows me a kiss. I take her hand; I take her to the park. We go for a walk, and I do not understand how time passes at all. I am happy when I see we have a good relationship".
4.8. Social Satisfaction
The theme relates to social conditions, economic conditions, access to health services, and satisfaction with various institutional support for the elderly. The basic themes, which led to this organizing theme include providing the elderly with free and supplementary insurance, free travel tours, suitable parks, and free medical services on holidays. Mentioning this theme of social satisfaction does not mean that the participants were satisfied with the current situation. However, it means that creating this mechanism by the government will significantly affect the healthy aging of the elderly. A total of 66-year-old women asked for free welfare services and said that "Those who do not have money, the government should help them, should provide them with free tours to visit holy shrines, and should make a good park with some equipment for the elderly to help them relieve their muscle pains".
4.9. Global Theme: Dynamic Aging
According to the themes and categories obtained from the current study, healthy aging can lead to dynamic aging for the elderly. The findings are essential because they are based on the lived experiences of the elderly to describe their healthy and successful aging according to their experiences. Themes such as satisfaction with marital life, healthy lifestyle, satisfaction with moral issues, spiritual orientation, independence and financial self-sufficiency, intra-generational dynamism, intergenerational dynamism, and social satisfaction reflect the fact that older people have shifted from a static world to a dynamic system to reflects the actual conditions of an interactive and changing context. This dynamic aging would have many consequences for the elderly. For example, the elderly increase their activities, accept changes, communicate with friends and acquaintances, and pursue purposeful activities instead of reducing their activities due to their age.
