Older Americans' life

According to my survey, the older Americans want to live alone after they retire. They do not want to rely on their grown children. They want to spend their life independently and happily on their own. I also asked my roommate her grandparents. She told me that her grandfather still working three days a week for a couple of hours in the museum. He feels bored and lonely if he does not do anything with his free time. He also enjoys travelling and walking. In my point of view, all the Americans are hardworking whatever their age will be. Americans do not want to spend their time without doing anything. For my country, the grandparents live with thier son or daughter's family. If one has a lot of childern, his/her children take turn to take care of them.
